DIRECTIVE 98/69/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 13 October 1998 relating to measures to be taken against air pollution by emissions from motor vehicles and amending Council Directive 70/220/EEC
THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,
Having regard to the Treaty establishing the European Community, and in particular Article 100a thereof,
Having regard to the proposals from the Commission (1),
Having regard to the Opinion of the Economic and Social Committee (2),
Acting in accordance with the procedure laid down in Article 189 b of the Treaty (3), in the light of the joint text approved on 29 June 1998 by the Conciliation Committee,
(1) Whereas measures should be adopted within the framework of the internal market;
(2) Whereas the first programme of action of the European Community on protection of the environment (4), approved by the Council on 22 November 1973, called for account to be taken of the latest scientific advances in combating atmospheric pollution caused by gases emitted from motor vehicles and for Directives adopted previously to be amended accordingly; whereas the fifth programme of action, which in its general approach was approved by the Council in its Resolution of 1 February 1993 (5), provided for additional efforts to be made for a considerable reduction in the present level of emissions of pollutants from motor vehicles; whereas this fifth programme also set targets in terms of emission reductions for various pollutants on the understanding that emissions from both mobile and stationary sources would have to be reduced;
(3) Whereas Council Directive 70/220/EEC (6) lays down the limit values for carbon monoxide and unburnt hydrocarbon emissions from the engines of such vehicles; whereas these limit values were first reduced by Council Directive 74/290/EEC (7) and supplemented, in accordance with Commission Directive 77/102/EEC (8), by limit values for permissible emissions of nitrogen oxides; whereas the limit values for these three types of pollution were successively reduced by Commission Directive 78/665/EEC (9) and Council Directives 83/351/EEC (10) and 88/76/EEC (11); whereas limit values for particulate pollutant emissions from diesel engines were introduced by Council Directive 88/436/EEC (12); whereas more stringent European standards for the emissions of gaseous pollutants from motor vehicles below 1 400 cm3 were introduced by Council Directive 89/458/EEC (13); whereas these standards have been extended to all passenger cars independently of their engine capacity on the basis of an improved European test procedure comprising an extra-urban driving cycle; whereas requirements relating to evaporative emissions and to the durability of emission-related vehicle components as well as more stringent particulate pollutant standards for motor vehicles equipped with diesel engines were introduced by Council Directive 91/441/EEC (14); whereas Directive 94/12/EC of the European Parliament and of the Council (15) introduced more stringent limit values for all pollutants and a new method for checking on the conformity of production; whereas passenger cars designed to carry more than six occupants and having a maximum mass of more than 2 500 kg, light commercial vehicles, and off-road vehicles, covered by Directive 70/220/EEC, which previously benefited from less stringent standards, have since been subject, pursuant to Council Directive 93/59/EEC (16) and Directive 96/69/EC of the European Parliament and of the Council (17), to standards as stringent as the respective standards for passenger cars, taking into account the specific conditions of these vehicles;
(4) Whereas an additional effort should be undertaken in order to commercialise more environmentally friendly vehicles; whereas, in the sectors of public and collective passenger transport and urban freight distribution, an increased share of more environmentally friendly vehicles should be aimed at;
(5) Whereas Article 4 of Directive 94/12/EC requires that the Commission propose standards which will be enforced after the year 2000, according to a new multi-faceted approach, based on a comprehensive assessment of costs and efficiency of all measures aimed at reducing road transport pollution; whereas the proposal should, besides the tightening of car emission standards, include complementary measures such as an improvement in fuel quality and a strengthening of the motor-vehicle inspection and maintenance programme; whereas the proposal should be based on the establishment of air quality criteria and associated emission reduction objectives and an evaluation of the cost-effectiveness of each package of measures, taking into account the potential contribution of other measures such as traffic management, enhancement of urban public transport, new propulsion technologies or the use of alternative fuels; whereas, given the urgency of community action on the limitation of pollutant emissions by motor vehicles, the present proposals are also based on present or anticipated best available anti-pollution technologies which are liable to speed up the replacement of polluting motor vehicles;
(6) Whereas an adequate framework should be created as soon as possible to accelerate the introduction on to the market of vehicles with innovative propulsion technologies and vehicles which use alternative fuels with a low environmental impact; whereas the introduction of vehicles with alternative fuels can produce a significant improvement in the quality of city air;
(7) Whereas, in order to help resolve the problem of atmospheric pollution, it is necessary to step in with a global strategy, encompassing the technological, management and tax aspects, for the development of sustainable mobility, taking into account the specific characteristics of the various European urban areas;
(8) Whereas the Commission has implemented a European programme on air quality, road traffic emissions, fuels and engines technologies (the Auto/Oil Programme) with a view to fulfilling the requirements of Article 4 of Directive 94/12/EC; whereas the Commission has implemented the APHEA Project which estimates the external costs of air pollution by motor vehicles at 0,4 % of EU GNP, and further assessments conclude that the external costs amount to 3 % of EU GNP, whereas the Commission has implemented the 'Car of Tomorrow` Action Plan which strives to contribute to the promotion of the 'Car of Tomorrow` which will be clean, safe, energy efficient and 'intelligent`; whereas this action plan enforces Community action promoting R & D leading to clean cars and whereas neither the R & D efforts undertaken in the framework of the 'Car of Tomorrow` Action Plan nor EU competitiveness in automobile R & D should be jeopardised; whereas the European motor vehicle and oil industries have carried out the European Programme on Emissions, fuels and Engine Technologies (EPEFE) to determine the contribution which can be made both by future vehicles and the fuels which propel them; whereas the Auto/Oil and EPEFE programmes strive to ensure that proposals for Directives on polluting emissions seek the best solutions for both the citizen and for the economy; whereas the need for Community action for the forthcoming Steps 2000 and 2005 has become urgent; whereas it has become apparent that a further improvement of car emission technology is necessary with a view to achieving air quality in the year 2010 as described in the Commission communication on the Auto/Oil Programme;
(9) Whereas it is important to give weight to factors such as fluctuations as a result of competitive developments, the real distribution of costs between the industries taking part with a view to the annual reduction of emissions, costs avoided elsewhere by investment in a given area and reductions in the burden on the economy;
(10) Whereas the improvement of requirements for new passenger cars and light commercial vehicles in Directive 70/220/EEC constitutes part of a consistent global Community strategy which will also include a revision of standards for light commercial vehicles and heavy duty vehicles from the year 2000, an improvement of motor fuels and more accurate assessment of in-service vehicle emission performance; whereas alongside these measures, additional cost-effective local measures will nevertheless be needed to achieve the air-quality criteria in the most polluting areas;
(11) Whereas Directive 70/220/EEC is one of the separate Directives under the type-approval procedure laid down by Council Directive 70/156/EEC of 6 February 1970 on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers (18); whereas the objective of reducing the level of pollutant emissions from motor vehicles cannot be sufficiently achieved by individual Member States and can therefore be better achieved by the approximation of the laws of the Member States relating to measures to be taken against air pollution by motor vehicles;
(12) Whereas reductions of the Type I test limits applicable from the year 2000 (corresponding to a drop of 40 % in nitrogen oxides, 40 % in total hydrocarbons, 30 % in carbon monoxide for petrol-driven passenger cars, 20 % in nitrogen oxides, 20 % in the combined value for hydrocarbons plus nitrogen oxides, 40 % in carbon monoxide, 35 % in particulates for indirect injection diesel passenger cars and 40 % in nitrogen oxides, 40 % in the combined value for hydrocarbons plus nitrogen oxides, 40 % in carbon monoxide and 50 % in particulates for direct-injection diesel passenger cars and a reduction of 20 % in nitrogen oxides, 65 % in hydrocarbons, 40 % in carbon monoxide and 35 % in particulates for diesel light commercial vehicles) have been identified as key measures to achieve sufficient medium-term air quality; whereas these reductions have been applied to hydrocarbons and nitrogen oxides on the assumption that nitrogen oxides represent respectively 45 % and 80 % of the weight of the combined value measured for petrol/diesel passenger cars complying with Directive 94/12/EC and Directive 96/69/EC respectively; whereas separate limit values are now normally fixed for petrol-driven vehicles in order to monitor the emissions of both pollutants; whereas a combined limit value is maintained for diesel vehicles for which the Stage 2000 standards are the most demanding, with a view to facilitating engineering of future engines; whereas these reductions will take into account the effect on real emissions of a modification also adopted for the test cycle with a view to better representing emissions after a cold start ('deletion of 40 s`);
(13) Whereas Commission Directive 96/44/EC (19) brought the test conditions of Directive 70/220/EEC into line with those of Council Directive 80/1268/EEC of 16 December 1980 relating to the carbon dioxide emissions and the fuel consumption of motor vehicles (20), in particular as far as the relationship between the reference mass of the vehicle and the equivalent inertia which is to be used is concerned; whereas it is now appropriate to align the reference mass definitions of vehicles of Category N1 Classes I, II and III with those of Directive 96/44/EC;
(14) Whereas new provisions for on-board diagnostics (OBD) should be introduced with a view to permitting an immediate detection of failure of anti-pollution vehicle equipment and thus allowing a significant upgrading of the maintenance of initial emissions performance on in-service vehicles through periodic or kerbside control; whereas, however, OBD are at a less developed stage for diesel vehicles and cannot be fitted on all such vehicles before 2005; whereas installing an on-board measurement system (OBM) or other systems to detect any faults by measuring individual pollutants emitted shall be permissible provided that the OBD system integrity is maintained; whereas in order for the Member States to ensure that vehicle owners meet their obligation to repair faults once they have been indicated, the distance travelled since the fault is indicated shall be recorded; whereas on-board diagnostics systems must offer unrestricted and standardised access; whereas motor vehicle manufacturers must provide the information required for the diagnosis, servicing or repair of the vehicle; whereas such access and such information are required to ensure that vehicles may be inspected, serviced and repaired without hindrance throughout the European Union, and that competition in the market for vehicle parts and repairs is not distorted to the disadvantage of part manufacturers, independent vehicle-part wholesalers, independent repair garages and consumers; whereas manufacturers of spare or retrofit parts will be obliged to make the parts they manufacture compatible with the on-board diagnostic system concerned with a view to fault-free operation assuring the user against malfunctions;
(15) Whereas the Type IV test which makes it possible to determine the evaporative emissions from vehicles with positive-ignition engines can be improved better to represent real evaporative emissions as well as the status of measuring techniques;
(16) Whereas to adapt the behaviour of the exhaust-emission control systems of vehicles with positive-ignition engines to the actual requirements of practice, a new test should be introduced to measure emissions at low temperatures;
(17) Whereas the characteristics of the reference fuels used for emission testing should reflect the evolution of the market fuel specifications to be available following legislation on the quality of petrol and diesel fuels;
(18) Whereas a new method for checking conformity of production on in-service vehicles has been identified as a cost-effective accompanying measure, and is included in the emissions Directive with the objective of implementation in the year 2001;
(19) Whereas the circulation of obsolete vehicles, which causes many times more pollution than vehicles now being marketed, is an important source of road transport pollution; whereas measures to promote the faster replacement of existing vehicles with vehicles having a lower environmental impact should be investigated;
(20) Whereas Member States should be allowed, by means of tax incentives, to expedite the placing on the market of vehicles which satisfy the requirements adopted at Community level, such incentives having to comply with the provisions of the Treaty and satisfy certain conditions intended to avoid distortions of the internal market; whereas this Directive does not affect the Member States' right to include emissions of pollutants and other substances in the basis for calculating road traffic taxes on motor vehicles;
(21) Whereas with a view to the harmonious development of the internal market and the protection of consumer interests, a binding long-term approach is required; whereas it is therefore necessary to establish a two-stage approach with mandatory limit values to be applied from the years 2000 and 2005 which can be used for the purpose of granting tax incentives to encourage the early introduction of vehicles containing the most advanced anti-pollution equipment;
(22) Whereas the Commission will closely monitor technological developments in emission control and, where appropriate, will propose the adaptation of this Directive; whereas the Commission is carrying out research projects to deal with outstanding questions, the findings of which will be incorporated in a proposal for future legislation after the year 2005;
(23) Whereas Member States may take measures to encourage the retrofitting of older vehicles with emission control devices and components;
(24) Whereas Member States may take measures to encourage faster progress towards replacing existing vehicles with low-emission vehicles;
(25) Whereas Article 5 of Directive 70/220/EEC lays down that the amendments which are necessary to adapt the requirements of the Annexes to technical progress shall be adopted in accordance with the procedure laid down in Article 13 of Directive 70/156/EEC; whereas in the meantime several other Annexes have been added to the Directive and it is essential that all Annexes to Directive 70/220/EEC can be adapted to technical progress in accordance with the said procedure;
(26) Whereas is modus vivendi between the European Parliament, the Council and the Commission concerning the implementing measures for acts adopted in accordance with the procedure laid down in Article 189b of the Treaty was concluded on 20 December 1994 (21); whereas this modus vivendi applies inter alia to measures taken in accordance with Article 13 of Directive 70/156/EEC;
(27) Whereas Directive 70/220/EEC should be amended accordingly,
HAVE ADOPTED THIS DIRECTIVE:

- Category N1, Classes II and III limit values for cold start in low temperature ambient air (266 K) (- 7° C),
- Community provisions for improved roadworthiness testing,
- the threshold limit values for OBD for 2005/6 for M1 and N1 vehicles,
- examination of Type V testing, including the possibility of abolishing it.
2. After 31 December 1999 the Commission shall submit further proposals for legislation to come into force after 2005 which consider:
- modification to the durability requirements, including extending the durability test,
- fuel quality standards including in particular in the light of vehicle technology,
- the contribution of possible measures, including those relating to fuels and vehicles, to the attainment of longer term Community objectives on air quality, taking into account technological developments and the results of new air pollution related research including effects of particulate matter on human health,
- the potential and feasibility of local measures to reduce vehicle emissions; in this context the contribution of transport and other policy measures such as traffic management, urban public transport, enhanced inspection and maintenance and vehicle scrappage schemes should be evaluated,
- the particular situation of captive fleets and the potential for emission reductions related to the use by such fleets of fuels with very stringent environmental specifications,
- the potential emission reductions to be gained from fixing the environmental specifications of fuels to be used in agricultural tractors as covered by Directive 74/150/EEC and in internal combustion engines to be installed in non-road mobile machinery as covered by Directive 97/68/EC,
- requirements for the operation of an on-board measurement system (OBM).
3. All proposals shall take into account the following background considerations:
- evaluation of the impact of the provisions of this Directive in terms of their contribution to air quality, examination of technical feasibility and cost-effectiveness including an evaluation of the benefits and availability of enhanced technology,
- compatibility with the attainment of other Community objectives, such as regarding the attainment of air quality objectives and other related objectives such as acidification and eutrophication and the reduction of greenhouse gas emissions,
- noxious pollutant emissions in the Community from transport and non-transport sources and an estimate of the contribution that existing and pending and potential emission reduction measures from all sources could make towards improving air quality,
- emissions from direct-injection petrol engines including particulate emissions,
- developments in exhaust purification at full load,
- development of alternative fuels and new propulsion technologies,
- progress towards the industrial availability of key after-treatment systems such as DeNOx catalysts and traps and the technical feasibility of achieving the implementation date for diesel engines,
- improvements in the test procedures for small particulates,
- refinery technologies and the supply situation and qualities of crude oil available to the Community,
- the contribution that selective and differentiated fiscal measures could make to reducing vehicle emissions without any negative impact on the functioning of the internal market, taking into account the effects of revenue losses on neighbouring countries.
1. By 1 January 2000, the Commission shall submit a report to the European Parliament and the Council on the drawing up of a standard electronic format for repair information taking account of relevant international standards.
By 30 June 2002 the Commission shall submit a report to the European Parliament and the Council on the development of on-board diagnostics (OBD) giving its opinion on the need for an extension of the OBD procedure and on requirements for the operation of an on-board measurement system (OBM). On the basis of the report, the Commission will submit a proposal for measures to enter into force no later than 1 January 2005 to include the technical specifications and corresponding annexes in order to provide for the type approval of OBM systems ensuring at least equivalent levels of monitoring to the OBD system and which shall be compatible with these systems.
The Commission shall submit a report to the European Parliament and the Council on the extension of OBD to cover other electronic vehicle control systems relating to active and passive safety, inter alia in a manner which is compatible with emission control systems.
2. By 1 January 2001 the Commission shall take appropriate measures to ensure that replacement or retro-fitted components can be brought to the market. Such measures shall include suitable approval procedures for replacement parts to be defined as soon as possible for those emission control components that are critical to the correct functioning of OBD systems.
3. By 30 June 2000 the Commission shall take appropriate measures to ensue that the development of replacement or retro-fit components which are critical to the correct functioning of the OBD system is not restricted by the unavailability of pertinent information, unless that information is covered by intellectual property rights or constitutes specific know-how of the manufacturers or the OEM (Original Equipment Manufacturers) suppliers: in this case the necessary technical information shall not be improperly withheld.
4. In addition the Commission shall submit, by 30 June 2000, appropriate proposals to ensure that spare and retrofit parts are compatible inter alia with the specifications of the appropriate on-board diagnostic system, so that repair, replacement and fault-free operation are possible. The type-approval procedure laid down in the Annex to this Directive shall serve as a basis for this.
Member States may make provision for tax incentives only in respect of motor vehicles in series production which comply with Directive 70/220/EEC, as amended by this Directive. Such incentives shall comply with the provisions of the Treaty and satisfy the following conditions:
- they shall apply to all new series-production vehicles offered for sale on the market of a Member State which comply in advance with the mandatory limit values set out in row A of the table in section 18.104.22.168 of Annex I to Directive 70/220/EEC, as amended by this Directive, and thereafter as from 1 January 2000 for vehicles in Category M1 and Category N1, Class I, and, with effect from 1 January 2001, for vehicles in Category N1, Classes II and III, which comply with the limit values set out in row B of the same table,
- they shall be terminated with effect from the application of the emission limit values laid down in Article 2(3) for new motor vehicles, or with effect from the dates laid down in Article 2(4),
- for each type of motor vehicle, they shall not exceed the additional cost of the technical solutions introduced to ensure compliance with the values set in Article 2(3) or Article 2(5) and of their installation on the vehicle.
The Commission shall be informed in sufficient time of plans to institute or change the incentives referred to in the first subparagraph, so that it can submit its observations.
Member States may inter alia introduce tax or financial incentives for the re-equipment of in-use vehicles to meet the values laid down in this Directive or previous amendments to Directive 70/220/EEC, and for laying up vehicles which do not comply.
Rules for a type-approval for vehicles with alternative propulsion systems and vehicles using alternative fuels shall be further defined as appropriate.
This Directive shall be brought into effect at the same time as, and in accordance with the same timetable for, the introduction of measures specified in Directive 98/70/EC (22).
1. Member States shall adopt and publish the laws, regulations and administrative provisions necessary to comply with this Directive with effect as from nine months after this Directive enters into force. They shall forthwith inform the Commission thereof.
When Member States adopt these measures, they shall contain a reference to this Directive or shall be accompanied by such reference on the occasion of their official publication. The methods of making such a reference shall be laid down by Member States.
2. Member States shall communicate to the Commission the texts of the main provisions of national law which they adopt in the field covered by this Directive.
This Directive shall enter into force on the day of its publication in the Official Journal of the European Communities.
This Directive is addressed to the Member States.

'7.1.7. On the basis of the audit referred to in 7.1.1, the type-approval authority must either:
- decide that conformity in use is satisfactory and not take any further action, or
- decide that the information is insufficient or the conformity of vehicles in use is unsatisfactory, and proceed to have vehicles tested in accordance with Appendix 3 to this Annex.
18.104.22.168. Where type I tests are considered necessary to check the conformity of emission control devices with the requirements for their performance while in service, such tests must be carried out using a test procedure meeting the statistical criteria defined in Appendix 4 to this Annex.
22.214.171.124. The type-approval authority, in cooperation with the manufacturer, must select a sample of vehicles with sufficient mileage whose use under normal conditions can be reasonably assured. The manufacturer must be consulted on the choice of the vehicles in the sample and be allowed to attend the confirmatory checks of the vehicles.
126.96.36.199. The manufacturer is authorized, under the supervision of the type-approval authority, to carry out checks, even of a destructive nature, on those vehicles with emission levels in excess of the limit values with a view to establishing possible causes of deterioration which cannot be attributed to the manufacturer himself (e. g. use of leaded petrol before the test date). Where the results of the checks confirm such causes, those test results are excluded from the conformity check.
188.8.131.52. Where the type-approval authority is not satisfied with the results of the tests in accordance with the criteria defined in Appendix 4, the remedial measures referred to in Article 11 (2) and in Annex X to Directive 70/156/EEC are extended to vehicles in service belonging to the same vehicle type which are likely to be affected with the same defects in accordance with section 6 of Appendix 3.
The plan of remedial measures presented by the manufacturer must be approved by the type-approval authority. The manufacturer is responsible for the execution of the remedial plan as approved.
The type-approval authority must notify its decision to all Member States within 30 days. The Member States may require the same plan of remedial measures be applied to all vehicles of the same type registered in their territory.
184.108.40.206. If a Member State has established that a vehicle type does not conform to the applicable requirements of Appendix 3 to this Annex, it must notify without delay the Member State which granted the original type-approval in accordance with the requirements of Article 11 (3) of Directive 70/156/EEC.
Then, subject to the provision of Article 11(6) of Directive 70/156/EEC, the competent authority of the Member State which granted the original type-approval shall inform the manufacturer that a vehicle type fails to satisfy the requirements of these provisions and that certain measures are expected of the manufacturer. The manufacturer shall submit to the authority, within two months after this notification, a plan of measures to overcome the defects, the substance of which should correspond to the requirements of sections 6.1 to 6.8 of Appendix 3. The competent authority which granted the original type-approval shall, within two months, consult the manufacturer in order to secure agreement on a plan of measures and on carrying out the plan. If the competent authority which granted the original type-approval establishes that no agreement can be reached, the procedure pursuant to Article 11(3) and (4) of Directive 70/156/EEC shall be initiated.`

IN-SERVICE CONFORMITY CHECK
This Appendix sets out the criteria referred to in section 7.1.7 of this Annex regarding the selection of vehicles for testing and the procedures for the in-service conformity control.
2. SELECTION CRITERIA
The criteria for acceptance of a selected vehicle are defined in sections 2.1 to 2.8 of this Appendix. Information is collected by vehicle examination and an interview with the owner/driver.
2.1. The vehicle must belong to a vehicle type that is type-approved under this Directive and covered by a certificate of conformity in accordance with Directive 70/156/EEC. It must be registered and used in the European Community.

2.7. There must be no indication of any problem that might jeopardize the safety of laboratory personnel.
2.8. All anti-pollution system components on the vehicle must be in conformity with the applicable type-approval.
3. DIAGNOSIS AND MAINTENANCE
Diagnosis and any normal maintenance necessary must be performed on vehicles accepted for testing, prior to measuring exhaust emissions, in accordance with the procedure laid down in section 3.1 to 3.7.
3.1. The following checks must be carried out: checks on air filter, all drive belts, all fluid levels, radiator cap, all vacuum hoses and electrical wiring related to the antipollution system for integrity; checks on ignition, fuel metering and anti-pollution device components for maladjustments and/or tampering. All discrepancies must be recorded.

Appendix 4 (1)
(1) The provisions laid down in Appendix 4 must be re-examined and completed without delay in accordance with the procedure laid down in Article 13 of Directive 70/156/EEC.
STATISTICAL PROCEDURE FOR IN-SERVICE CONFORMITY TESTING
1. This Appendix describes the procedure to be used to verify the in-service conformity requirements for the type I test.
2. Two different procedures are to be followed:
1. One dealing with vehicles identified in the sample, due to an emission-related defect, causing outliers in the results (section 3).
2. The other dealing with the total sample (section 4).
3. PROCEDURE TO BE FOLLOWED WITH OUTLYING EMITTERS IN THE SAMPLE.
3.1. A vehicle is said to be an outlying emitter, when for any regulated component the limit value as shown in section 126.96.36.199 of Annex I is exceeded significantly.
3.2. With a minimum sample size of 3, and a maximum sample size as determined by the procedure of paragraph 4, the sample is scanned for the occurrence of outlying emitters.
3.3. When an outlying emitter is found, the cause of the excess emission must be determined.
3.4. When more than one vehicle is found to be an outlying emitter, due to the same cause, the sample is regarded as having failed.
3.5. When only one outlying emitter has been found, or when more than one outlying emitter is found, but due to different causes, the sample is increased by one vehicle, unless the maximum sample size has already been reached.
3.5.1. When in the increased sample more than one vehicle is found to be an outlying emitter, due to the same cause, the sample is regarded as having failed.
3.5.2. When in the maximum sample size not more than one outlying emitter is found, where the excess emission is due to the same cause, the sample is regarded as having passed with regard to the requirements of section 3 of this Appendix.
3.6. Whenever a sample is increased due to the requirements of 3.5, the statistical procedure of paragraph 4 is applied to the increased sample.
4. PROCEDURE TO BE FOLLOWED WITHOUT SEPARATE EVALUATION OF OUTLYING EMITTERS IN THE SAMPLE.
4.1. With a minimum sample size of three the sampling procedure is set so that the probability of a batch passing a test with 40 % of the production defective is 0,95 (producer's risk = 5 %) while the probability of a batch being accepted with 75 % of the production defective is 0,15 (consumer's risk = 15 %).
4.2. For each of the pollutants given in section 6.2.1 of Annex I, the following procedure is used (see Figure I/7).
L = the limit value for the pollutant,
Xi = the value of the measurement for the i-th vehicle of the sample,
n = the current sample number.
4.3. The test statistic quantifying the number of non-conforming vehicles, i. e. xi > L, is computed for the sample.
- if the test statistic does not exceed the pass decision number for the sample size given in the following table, a pass decision is reached for the pollutant,
- if the test statistic equals or exceeds the fail decision number for the sample size given in the following table, a fail decision is reached for the pollutant,
- otherwise, an additional vehicle is tested and the procedure is applied to the sample with one extra unit.
In the following table the pass and fail decision numbers are computed in accordance with the International Standard ISO 8422:1991.
5. A sample is regarded as having passed the test when it has passed both the requirements of sections 3 and 4 of this Appendix.

This Annex describes the procedure for the Type IV test in accordance with section 5.3.4 of Annex I.
This procedure describes a method for a determination of the loss of hydrocarbons by evaporation from the fuel systems of vehicles with positive-ignition engines.
2. DESCRIPTION OF TEST
The evaporative emission test (Figure VI.1) is designed to determine hydrocarbon evaporative emissions as a consequence of diurnal temperatures fluctuation, hot soaks during parking, and urban driving. The test consists of these phases:
- test preparation including an urban (Part One) and extra-urban (Part Two) driving cycle,
- hot soak loss determination,
- diurnal loss determination.
Mass emissions of hydrocarbons from the hot soak and the diurnal loss phases are added up to provide an overall result for the test.
3. VEHICLE AND FUEL
3.1.1. The vehicle must be in good mechanical condition and have been run in and driven at least 3 000 km before the test. The evaporative emission control system must be connected and have been functioning correctly over this period and the carbon canister(s) must have been subject to normal use, neither undergoing abnormal purging nor abnormal loading.
3.2.1. The appropriate reference fuel must be used, as defined in Annex IX to this Directive.
4. TEST EQUIPMENT FOR EVAPORATIVE TEST
4.1. Chassis dynamometer
The chassis dynamometer must meet the requirements of Annex III.
4.2. Evaporative emission measurement enclosure
The evaporative emission measurement enclosure must be a gas-tight rectangular measuring chamber able to contain the vehicle under test. The vehicle must be accessible from all sides and the enclosure when sealed must be gas tight in accordance with Appendix 1. The inner surface of the enclosure must be impermeable and non-reactive to hydrocarbons. The temperature conditioning system must be capable of controlling the internal enclosure air temperature to follow the prescribed temperature versus time profile throughout the test, and an average tolerance of ± 1 K over the duration of the test.
The control system must be tuned to provide a smooth temperature pattern that has a minimum of overshoot, hunting, and instability about the desired long-term ambient temperature profile. Interior surface temperatures must not be less than 278 °K (5 °C) nor more than 320 °K (55 °C) at any time during the diurnal emission test. Wall design must be such as to promote good dissipation of heat. Interior surface temperatures must not be below 293 °K (20 °C), nor above 325 °K (52 °C) for the duration of the hot soak test.
To accommodate the volume changes due to enclosure temperature changes, either a variable-volume or fixed-volume enclosure may be used.
4.2.1. Variable-volume enclosure
The variable-volume enclosure expands and contracts in response to the temperature change of the air mass in the enclosure. Two potential means of accommodating the internal volume changes are movable panel(s), or a bellows design, in which an impermeable bag or bags inside the enclosure expand(s) and contracts(s) in response to internal pressure changes by exchanging air from outside the enclosure. Any design for volume accommodation must maintain the integrity of the enclosure as specified in Appendix 1 over the specified temperature range.
Any method of volume accommodation must limit the differential between the enclosure internal pressure and the barometric pressure to a maximum value of ± 5 hPa.
The enclosure must be capable of latching to a fixed volume. A variable volume enclosure must be capable of accommodating a ± 7 % change from its 'nominal volume` (see Appendix 1 section 2.1.1), taking into account temperature and barometric pressure variation during testing.
4.2.2. Fixed-volume enclosure
The fixed-volume enclosure must be constructed with rigid panels that maintain a fixed enclosure volume, and meet the requirements below.
22.214.171.124. The enclosure must be equipped with an outlet flow stream that withdrawns air at a low, constant rate from the enclosure throughout the test. An inlet flow stream may provide make-up air to balance the outgoing flow with incoming ambient air. Inlet air must be filtered with activated carbon to provide a relatively constant hydrocarbon level. Any method of volume accommodation must maintain the differential between the enclosure internal pressure and the barometric pressure between 0 and -5 hPa.
126.96.36.199. The equipment must be capable of measuring the mass of hydrocarbon in the inlet and outlet flow streams with a resolution of 0,01 gram. A bag sampling system may be used to collect a proportional sample of the air withdrawn from and admitted to the enclosure. Alternatively, the inlet and outlet flow streams may be continuously analysed using an on-line FID analyser and integrated with the flow measurements to provide a continuous record of the mass hydrocarbon removal.
4.3. Analytical systems
4.3.1. Hydrocarbon analyser
188.8.131.52. The atmosphere within the chamber is monitored using a hydrocarbon detector of the flame ionization detector (FID) type. Sample gas must be drawn from the mid-point of one side wall or roof of the chamber and any bypass flow must be returned to the enclosure, preferably to a point immediately downstream of the mixing fan.
184.108.40.206. The hydrocarbon analyser must have a response time to 90 % of final reading of less than 1,5 seconds. Its stability must be better than 2 % of full scale at zero and at 80 % ± 20 % of full scale over a 15-minute period for all operational ranges.
220.127.116.11. The repeatability of the analyser expressed as one standard deviation must be better than 1 % of full scale deflection at zero and at 80 % ± 20 % of full scale on all ranges used.
18.104.22.168. The operational ranges of the analyser must be chosen to give best resolution over the measurement, calibration and leak checking procedures.
4.3.2. Hydrocarbon analyser data recording system
22.214.171.124. The hydrocarbon analyser must be fitted with a device to record electrical signal output either by strip chart recorder or other data processing system at a frequency of at least once per minute. The recording system must have operating characteristics at least equivalent to the signal being recorded and must provide a permanent record of results. The record must show a positive indication of the beginning and end of the hot soak or diurnal emission test (including beginning and end of sampling periods along with the time elapsed between start and completion of each test).
>REFERENCE TO A GRAPHIC>
4.4. Fuel tank heating (only applicable for gasoline canister load option)
4.4.1. The fuel in the vehicle tank(s) must be heated by a controllable source of heat; for example a heating pad of 2 000 W capacity is suitable. The heating system must apply heat evenly to the tank walls beneath the level of the fuel so as not to cause local overheating of the fuel. Heat must not be applied to the vapour in the tank above the fuel.
4.4.2. The tank heating device must make it possible to heat the fuel in the tank evenly by 14 °K from 289 °K (16 °C) within 60 minutes, with the temperature sensor position as in 5.1.1. The heating system must be capable of controlling the fuel temperature to ± 1,5 °K of the required temperature during the tank heating process.
4.5. Temperature recording
4.5.1. The temperature in the chamber is recorded at two points by temperature sensors which are connected so as to show a mean value. The measuring points are extended approximately 0,1 m into the enclosure from the vertical centre line of each side wall at a height of 0,9 ± 0,2 m.
4.5.2. The temperatures of the fuel tank(s) are recorded by means of the sensor positioned in the fuel tank as in 5.1.1 in the case of use of the gasoline canister load option (5.1.5).
4.5.3. Temperatures must, throughout the evaporative emission measurements, be recorded or entered into a data processing system at a frequency of at least once per minute.
4.5.4. The accuracy of the temperature recording system must be within ± 1,0 °K and the temperature must be capable of being resolved to ± 04, °K.
4.5.5. The recording or data processing system must be capable of resolving time to ± 15 seconds.
4.6. Pressure recording

4.6.2. The accuracy of the pressure recording system must be within ± 2 hPa and the pressure must be capable of being resolved to ± 0,2 hPa.
4.6.3. The recording or data processing system must be capable of resolving time to ± 15 seconds.
4.7.1. By the use of one or more fans or blowers with the SHED door(s) open it must be possible to reduce the hydrocarbon concentration in the chamber to the ambient hydrocarbon level.
4.7.2. The chamber must have one or more fans or blowers of likely capacity 0,1 to 0,5 m3s-1 with which to thoroughly mix the atmosphere in the enclosure. It must be possible to attain an even temperature and hydrocarbon concentration in the chamber during measurements. The vehicle in the enclosure must not be subjected to a direct stream of air from the fans or blowers.
4.8.1. The following pure gases must be available for calibration and operation:
- purified synthetic air (purity: NUM>CHC, f 7 Pf
- >NUM>CHC, i 7 Pi >DEN>Ti
) + MHC, out - MHC, i
MHC = hydrocarbon mass in grams
MHC,out = mass of hydrocarbon exiting the enclosure, in the case of fixed-volume enclosures for diurnal emission testing (grams).
MHC,i = mass of hydrocarbon entering the enclosure, in the case of fixed-volume enclosures for diurnal emission testing (grams).
CHC = measured hydrocarbon concentration in the enclosure (ppm (volume) C1 equivalent),
V = net enclosure volume in cubic metres corrected for the volume of the vehicle, with the windows and the luggage compartment open. If the volume of the vehicle is not determined a volume of 1,42 m³ is subtracted.
T = ambient chamber temperature, in °K,
P = barometric pressure in kPA,
= hydrogen to carbon ration,
k = 1,2 7 (12 + >NUM>H/
i is the initial reading,
f is the final reading,
is taken to be 2,33 for diurnal test losses,
is taken to be 2,20 for hot soak losses.
6.2. Overall results of test
The overall hydrocarbon mass emission for the vehicle is taken to be:
Mtotal = MDI + MHS
Mtotal = overall mass emissions of the vehicle (grams),
MDI = hydrocarbon mass emission for diurnal test (grams),
MHS = hydrocarbon mass emission for the hot soak (grams).`
35. Sections 1 and 2 read as follows:
'1. CALIBRATION FREQUENCY AND METHODS
1.1. All equipment must be calibrated before its initial use and then calibrated as often as necessary and in any case in the month before type-approval testing. The calibration methods to besued are described in this Appendix.
1.2. Normally the series of temperatures which are mentioned firstly must be used. The series of temperatures within square brackets may alternatively be used.
2. CALIBRATION OF THE ENCLOSURE
2.1. Initial determination of enclosure internal volume
2.1.1. Before its initial use, the internal volume of the chamber must be determined as follows. The internal dimensions of the chamber are carefully measured, allowing for any irregularities such as bracing struts. The internal volume of the chamber is determined from these measurements.
For variable-volume enclosures, the enclosure must be latched to a fixed volume when the enclosure is held at an ambient temperature of 303 °K (30 °C) [(302 °K (29 °C)]. This nominal volume must be repeatable within ± 0,5 % of the reported value.
2.1.2. The net internal volume is determined by subtracting 1,42 m3 from the internal volume of the chamber. Alternatively the volume of the test vehicle with the luggage compartment and windows open may be used instead of the 1,42 m3.
2.1.3. The chamber must be checked as in 2.3. If the propane mass does not agree with the injected mass to within ± 2 % then corrective action is required.
2.2. Determination of chamber background emissions
This operation determines that the chamber does not contain any materials that emit significant amounts of hydrocarbons. The check must be carried out at the enclosure's introduction to service, after any operations in the enclosure which may affect background emissions and at a frequency of at least once per year.
2.2.1. Variable-volume enclosures may be operated in either latched or unlatched volume configuration, as described in 2.1.1 Ambient temperatures must be maintained at 308 °K ± 2 °K (35° ± 2 °C) [309 °K ± 2 °K (36° ± 2 °C)], throughout the 4-hour period mentioned below.
2.2.2. Fixed volume enclosures must be operated with inlet and outlet flow streams closed. Ambient temperatures must be maintained at 308 °K ± 2 °K (35° ± 2 °C) [309 °K ± 2 °K (36° ± 2 °C)] throughout the four-hour period mentioned below.
2.2.3. The enclosure may be sealed and the mixing fan operated for a period of up to 12 hours before the four-hour background sampling period begins.
2.2.4. The analyser (if required) must be calibrated, then zeroed and spanned.
2.2.5. The enclosure must be purged until a stable hydrocarbon reading is obtained, and the mixing fan turned on if not already on.
2.2.6. The chamber is then sealed and the background hydrocarbon concentration, temperature and barometric pressure are measured. These are the initial readings CHC,i, Pi and Ti used in the enclosure background calculation.
2.2.7. The enclosure is allowed to stand undisturbed with the mixing fan on for a period of four hours.
2.2.8. At the end of this time the same analyser is used to measure the hydrocarbon concentration in the chamber. The temperature and the barometric pressure are also measured. These are the final readings CHC,f, Pf and Tf.
2.2.9. The change in mass of hydrocarbons in the enclosure must be calculated over the time of the test in accordance with 2.4 and must not exceed 0,05 g.
2.3. Calibration and hydrocarbon retention test of the chamber
The calibration and hydrocarbon retention test in the chamber provides a check on the calculated volume in 2.1 and also measures any leak rate. The enclosure leak rate must be determined at the enclosure's introduction to service, after any operations in the enclosure which may affect the integrity of the enclosure, and at least monthly thereafter. If six consecutive monthly retention checks are successfully completed without corrective action, the enclosure leak rate may be determined quarterly thereafter as long as no corrective action is required.
2.3.1. The enclosure must be purged until a stable hydrocarbon concentration is reached. The mixing fan is turned on, if not already switched on. The hydrocarbon analyser is zeroed, calibrated if required, and spanned.
2.3.2. On variable-volume enclosures the enclosure must be latched to the nominal volume position. On fixed-volume enclosures the outlet and inlet flow streams must be closed.
2.3.3. The ambient temperature control system is then turned on (if not already on) and adjusted for an initial temperature of 308 °K (35 °C) [309 °K (36 °C)].
2.3.4. When the enclosure stabilizes at 308 °K ± 2 °K (35° ± 2 °C) [309 °K ± 2 °K (36° ± 2 °C)], the enclosure is sealed and the background concentration, temperature and barometric pressure measured. These are the initial readings CHC,i, Pi and Ti used in the enclosure calibration.
2.3.5. A quantity of approximately 4 grams of propane is injected into the enclosure. The mass of propane must be measured to an accuracy and precision of ± 02, % of the measured value.
2.3.6. The contents of the chamber must be allowed to mix for five minutes and then the hydrocarbon concentration, temperature and barometric pressure are measured. These are the final readings CHC,f, Pf and Tf for the calibration of the enclosure as well as the initial readings CHC,i, Pi and Ti for the retention check.
2.3.7. On the basis of the readings taken in 2.3.4 and 2.3.6 and the formula in 2.4, the mass of propane in the enclosure is calculated. This must be within ± 2 % of the mass of propane measured in 2.3.5..
2.3.8. For variable-volume enclosures the enclosure must be unlatched from the nominal volume configuration. For fixed-volume enclosures, the outlet and inlet flow streams must be opened.
2.3.9. The process is then begun of cycling the ambient temperature from 308 °K (35 °C) to 293 °K (20 °C) and back to 308 °K (35 °C) [308,6 °K (35,6 °C) to 295,2 °K (22,2 °C) and back to 308,6 °K (35,6 °C)] over a 24-hour period according to the profile [alternative profile] specified in Appendix 2 within 15 minutes of sealing the enclosure. (Tolerances as specified in section 5.7.1 of Annex VI).
2.3.10. At the completion of the 24-hour cycling period, the final hydrocarbon concentration, temperature and barometric pressure are measured and recorded. These are the final readings CHC,f, Tf and Pf for the hydrocarbon retention check.
2.3.11. Using the formula in 2.4, the hydrocarbon mass is then calculated from the readings taken in 2.3.10 and 2.3.6. The mass may not differ by more than 3 % from the hydrocarbon mass given by 2.3.7.
The calculation of net hydrocarbon mass change within the enclosure is used to determine the chamber's hydrocarbon background and leak rate. Initial and final readings of hydrocarbon concentration, temperature and barometric pressure are used in the following formula to calculate the mass change.
MHC = k 7 V 710-4 7 (
>NUM>CHC, f 7 Pf
- >NUM>CHC, i 7 Pi >DEN>Ti
) + MHC, out - MHC, i
MHC = hydrocarbon mass in grams
MHC,out = mass of hydrocarbon exiting the enclosure, in the case of fixed-volume enclosures for diurnal emission testing (grams)
MHC,i = mass of hydrocarbon entering the enclosure, in the case of fixed volume enclosures for diurnal emission testing (grams)
CHC = hydrocarbon concentration in the enclosure (ppm carbon (NB: ppm carbon = ppm propane x 3))
V = enclosure volume in cubic metres as measured in section 2.1.1.
T = ambient temperature in the enclosure in K,
P = barometric pressure in kPa,
k = 17,6;
i is the initial reading.
f is the final reading`

188.8.131.52. Vehicle cooling may be accomplished by force-cooling the vehicle to the test temperature. If cooling is augmented by fans, the fans must be placed in a vertical position so that the maximum cooling of the drive train and engine is achieved and not primarily the sump. Fans must not be placed under the vehicle.
184.108.40.206. The ambient temperature need only be stringently controlled after the vehicle has been cooled to:
266 °K (-7 °C) ± 2 °K,
as determined by a representative bulk oil temperature. A representative bulk oil temperature is the temperature of the oil measured near the middle of the oil, not at the surface or at the bottom of the oil sump. If tow or more diverse locations in the oil are monitored, they must all meet the temperature requirements.
220.127.116.11. The vehicle must be stored for at least one hour after is has been cooled to 266 °K (-7 °C) ± 2 °K, prior to the low ambient temperature tailpipe emission test. The ambient temperature (dry bulb) during this period must average 266 °K (-7 °C) ± 3 °K, and must:

not fall below 263 °K (-10 °C) or exceed 269 °K (-4 °C), for more than three consecutive minutes.
5. DYNAMOMETER PROCEDURE
5.1.1. The emission sampling is performed over a test procedure consisting of the part one cycle (Annex III - Appendix 1 Figure III.1.1). Engine start-up, immediate sampling, operation over the part one cycle and engine shut-down make a complete low ambient temperature test, with a total test time of 780 seconds. The tailpipe emissions are diluted with ambient air and a continuously proportional sample is collected for analysis. The exhaust gases collected in the bag are analysed for hydrocarbons, carbon monoxide, and carbon dioxide. A parallel sample of the dilution air is similarly analysed for carbon monoxide, hydrocarbons and carbon dioxide.
5.2. Dynamometer operation
5.2.1. Cooling fan
18.104.22.168. A cooling fan is positioned so that cooling air is appropriately directed to the radiator (water cooling) or to the air intake (air-cooling) and to the vehicle.
22.214.171.124. For front-engined vehicles, the fan must be positioned in front of the vehicle, within 300 mm of it. In the case of rear-engined vehicles or if the above arrangement is impractical, the cooling fan must be positioned so that sufficient air is supplied to cool the vehicle.
126.96.36.199. The fan speed must be such that, within the operating range of 10 km/h to at least 50 km/h, the linear velocity of the air at the blower outlet is within ± 5 km/h of the corresponding roller speed. The final selection of the blower must have the following characteristics:
- area: at least 0,2 m2,
- height of the lower edge above ground: approximately 20 cm.
As an alternative the blower speed must be at least 6 m/s (21,6 km/h). At the request of the manufacturer, for special vehicles (e. g. vans, off-road) the height of the cooling fan may be modified.
188.8.131.52. The vehicle speed as measured from the dynamometer roll(s) must be used (section 184.108.40.206 of Annex III).
5.2.3. Preliminary testing cycles may be carried out if necessary, to determine how best to actuate the accelerator and brake controls so as to achieve a cycle approximating to the theoretical cycle within the prescribed limits, or to permit sampling system adjustment. Such driving must be carried out before "START" according to Figure VII.1.
5.2.4. Humidity in the air must be kept low enough to prevent condensation on the dynamometer roll(s).
5.2.5. The dynamometer must be thoroughly warmed as recommended by the dynamometer manufacturer, and using procedures or control methods that assure stability of the residual frictional horsepower.
5.2.6. The time between dynamometer warming and the start of the emission test must be no longer than 10 minutes if the dynamometer bearings are not independently heated. If the dynamometer bearings are independently heated, the emission test must begin no longer than 20 minutes after dynamometer warming.
5.2.7. If the dynamometer horsepower must be adjusted manually, it must be set within one hour prior to the tailpipe emission test phase. The test vehicle may not be used to make the adjustment. The dynamometer, using automatic control of preselectable power settings, may be set at any time prior to the beginning of the emission test.
5.2.8. Before the emission test driving schedule may begin, the test cell temperature must be 266 °K (-7 °C) ± 2 °K, as measured in the air stream of the cooling fan with a maximum distance of 1 m-1,5 m from the vehicle.
5.2.9. During operation of the vehicle the heating and defrosting devices must be shut off.
5.2.10. The total driving distance or roller revolutions measured are recorded.
5.2.11. A four-wheel drive vehicle must be tested in a two-wheel drive mode of operation. The determination of the total road force for dynamometer setting is performed while operating the vehicle in its primary designed driving mode.
5.3. Performing the test
5.3.1. The provisions of sections 6.2 to 6.6, excluding 6.2.2, of Annex III apply in respect of starting the engine, carrying out the test and taking the emission samples. The sampling begins before or at the initiation of the engine start-up procedure and ends on conclusion of the final idling period of the last elementary cycle of the part one (urban driving cycle), after 780 seconds.
The first driving cycle starts with a period of 11 seconds idling as soon as the engine has started.
5.3.2. For the analysis of the sampled emissions the provisions of section 7.2 of Annex III apply. In performing the exhaust sample analysis the technical service must exercise care to prevent condensation of water vapour in the exhaust gas sampling bags.
5.3.3. For the calculations of the mass emissions the provisions of section 8 of Annex III apply.
6. OTHER REQUIREMENTS
6.1. Irrational emission control strategy
6.1.1. Any irrational emission control strategy which results in a reduction in effectiveness of the emission control system under normal operating conditions at low temperature driving, so far as not covered by the standardized emission tests, may be considered a defeat device."
Annexes VII, VIII and IX become Annexes VIII, IX and X.
38. The first subparagraph of section 6 reads as follows:
"At the start of the test (0 km), and every 10 000 km (± 400 km) or more frequently, at regular intervals until having covered 80 000 km, tailpipe emissions are measured in accordance with the type I test as defined in section 5.3.1 of Annex I. The limit values to be complied with are those laid down in section 220.127.116.11 of Annex I."

ON-BOARD DIAGNOSTICS (OBD) FOR MOTOR VEHICLES
This Annex applies to the functional aspects of on-board diagnostic (OBD) system for the emission control of motor vehicles.
For the purposes of this Annex:
2.1. 'OBD` means an on-board diagnostic system for emission control which must have the capability of identifying the likely area of malfunction by means of fault codes stored in computer memory.
2.2. 'Vehicle type` means a category of power-driven vehicles which do not differ in such essential engine and OBD system characteristics as defined in Appendix 2.
2.3. 'Vehicle family` means a manufacturer's grouping of vehicles which, through their design, are expected to have similar exhaust emission and OBD system characteristics. Each engine of this family must have complied with the requirements of this Directive.
2.4. 'Emission control system` means the electronic engine management controller and any emission-related component in the exhaust or evaporative system which supplies an input to or receives an output from this controller.
2.5. 'Malfunction indicator (MI)` means a visible or audible indicator that clearly informs the driver of the vehicle in the event of a malfunction of any emission-related component connected to the OBD system, or the OBD system itself.
2.6. 'Malfunction` means the failure of an emission-related component or system that would result in emissions exceeding the limits in section 3.3.2.
2.7. 'Secondary air` refers to air introduced into the exhaust system by means of a pump or aspirator valve or other means that is intended to aid in the oxidation of HC and CO contained in the exhaust gas stream.
2.8. 'Engine misfire` means lack of combustion in the cylinder of a positive-ignition engine due to absence of spark, poor fuel metering, poor compression or any other cause. In terms of OBD monitoring it is that percentage of misfires out of a total number of firing events (as declared by the manufacturer) that would result in emissions exceeding the limits given in section 3.3.2 or that percentage that could lead to an exhaust catalyst, or catalysts, overheating causing irreversible damage.
2.9. 'Type I test` means the driving cycle (Parts One and Two) used for emission approvals, as detailed in Annex III, Appendix 1.
2.10. 'A driving cycle` consists of engine start-up, driving mode where a malfunction would be detected if present, and engine shut-off.
2.11. 'A warm-up cycle` means sufficient vehicle operation such that the coolant temperature has risen by a least 22 °K from engine starting and reaches a minimum temperature of 343 °K (70 °C).
2.12. 'Fuel trim` refers to feedback adjustments to the base fuel schedule. Short-term fuel trim refers to dynamic or instantaneous adjustments. Long-term fuel trim refers to much more gradual adjustments to the fuel calibration schedule than short-term trim adjustments. These long-term adjustments compensate for vehicle differences and gradual changes that occur over time.
2.13. 'Calculated load value` refers to an indication of the current airflow divided by peak airflow, where peak airflow is corrected for altitude, if available. This definition provides a dimensionless number that is not engine specific and provides the service technician with an indication of the proportion of engine capacity that is being used (with wide open throttle as 100 %);
CLV = >NUM>Current airflow
>DEN>Peak airflow (at sea level)
× >NUM>Atmospheric pressure (at sea level)
2.14. 'Permanent emission default mode` refers to a case where the engine management controller permanently switches to a setting that does not require an input from a failed component or system where such a failed component or system would result in an increase in emissions from the vehicle to a level above the limits given in section 3.3.2.
2.15. 'Power take-off unit` means an engine-driven output provision for the purposes of powering auxiliary, vehicle mounted, equipment.
2.16. 'Access` means the availability of all emission-related OBD data including all fault codes required for the inspection, diagnosis, servicing or repair of emissions-related parts of the vehicle, via the serial interface for the standard diagnostic connection (pursuant to Appendix 1, section 126.96.36.199 of this Annex).
2.17. 'Unrestricted` means
- access not dependent on an access code obtainable only from the manufacturer, or a similar device, or
- access allowing evaluation of the data produced without the need for any unique decoding information, unless that information itself is standardised.
2.18. 'Standardised` means that all data stream information, including all fault codes used, shall be produced only in accordance with industry standards which, by virtue of the fact that their format and their permitted options are clearly defined, provide for a maximum level of harmonisation in the motor vehicle industry, and whose use is expressly permitted in this Directive.
3. REQUIREMENTS AND TESTS

18.104.22.168. Any other emission-related powertrain component connected to a computer must be monitored for circuit continuity.
3.3.5. Manufacturers may demonstrate to the approval authority that certain components or systems need not be monitored if, in the event of their total failure or removal, emissions do not exceed the emission limits given in 3.3.2.
3.4. A sequence of diagnostic checks must be initiated at each engine start and completed at least once provided that the correct test conditions are met. The test conditions must be selected in such a way that they all occur under normal driving as represented by the Type I test.
3.5. Activation of malfunction indicator (MI)
3.5.1. The OBD system must incorporate a malfunction indicator readily perceivable to the vehicle operator. The MI must not be used for any other purpose except to indicate emergency start-up or limp-home routines to the driver. The MI must be visible in all reasonable lighting conditions. When activated, it must display a symbol in conformity with ISO 2575 (1). A vehicle must not be equipped with more than one general purpose MI for emission-related problems. Separate specific purpose telltales (e. g. brake system, fasten seat belt, oil pressure, etc.) are permitted. The use of red for an MI is prohibited.
(1) International Standard ISO 2575-1982 (E), entitled 'Road vehicles - Symbols for controls indicators and tell-tales`, Symbol Number 4.36.
3.5.2. For strategies requiring more than two preconditioning cycles for MI activation, the manufacturer must provide data and/or an engineering evaluation which adequately demonstrates that the monitoring system is equally effective and timely in detecting component deterioration. Strategies requiring on average more than 10 driving cycles for MI activation are not accepted. The MI must also activate whenever the engine control enters a permanent emission default mode of operation if the emission limits given in 3.3.2 are exceeded. The MI must operate in a distinct warning mode, e. g. a flashing light, under any period during which engine misfire occurs at a level likely to cause catalyst damage, as specified by the manufacturer. The MI must also activate when the vehicle's ignition is in the 'key-on` position before engine starting or cranking and de-activate after engine starting if no malfunction has previously been detected.
3.6. Fault code storage
The OBD system must record code(s) indicating the status of the emission-control system. Separate status codes must be used to identify correctly functioning emission control systems and those emission control systems which need further vehicle operation to be fully evaluated. Fault codes that cause MI activation due to deterioration or malfunction or permanent emission default modes of operation must be stored and that fault code must identify the type of malfunction.
3.6.1. The distance travelled by the vehicle since the MI was activated must be available at any instant through the serial port on the standard link connector (2).
(2) This requirement is only applicable to vehicles with an electronic speed input to the engine management provided the ISO standards are completed within a lead time compatible with the application of the technology. It applies to all vehicles entering into service from 1 January 2005.`
3.6.2. In the case of vehicles equipped with positive-ignition engines, misfiring cylinders need not be uniquely identified if a distinct single or multiple cylinder misfire fault code is stored.
3.7. Extinguishing the MI
3.7.1. For misfire malfunctions at levels likely to cause catalyst damage (as specified by the manufacturer), the MI may be switched to the normal mode of activation if the misfire is not present any more, or if the engine is operated after changes to speed and load conditions where the level of misfire will not cause catalyst damage.
3.7.2. For all other malfunctions, the MI may be de-activated after three subsequent sequential driving cycles during which the monitoring system responsible for activating the MI ceases to detect the malfunction and if no other malfunction has been identified that would independently activate the MI.
3.8. Erasing a fault code
3.8.1. The OBD system may erase a fault code and the distance travelled and freeze-frame information if the same fault is not re-registered in at least 40 engine warm-up cycles.
FUNCTIONAL ASPECTS OF ON-BOARD DIAGNOSTIC (OBD) SYSTEMS
This Appendix describes the procedure of the test according to section 5 of this Annex. The procedure describes a method for checking the function of the on-board diagnostic (OBD) system installed on the vehicle by failure simulation of relevant systems in the engine management or emission control system. It also sets procedures for determining the durability of OBD systems.
The manufacturer must make available the defective components and/or electrical devices which would be used to simulate failures. When measured over the Type I test cycle, such defective components or devices must not cause the vehicle emissions to exceed the limits of section 3.3.2 by more than 20 %.
When the vehicle is tested with the defective component or device fitted, the OBD system is approved if the MI is activated.
2. DESCRIPTION OF TEST
2.1. The testing of OBD systems consists of the following phases:
- simulation of malfunction of a component of the engine management or emission control system,
- preconditioning of the vehicle with a simulated malfunction over preconditioning specified in section 6.2.1,
- driving the vehicle with a simulated malfunction over the Type I test cycle and measuring the emissions of the vehicle,
- determining whether the OBD system reacts to the simulated malfunction and indicates malfunction in an appropriate manner to the vehicle driver.
2.2. Alternatively, at the request of the manufacturer, malfunction of one or more components may be electronically simulated according to the requirements of section 6.
2.3. Manufacturers may request that monitoring take place outside the Type I test cycle if it can be demonstrated to the authority that monitoring during conditions encountered during the Type I test cycle would impose restrictive monitoring conditions when the vehicle is used in service.

6.5. Diagnostic signals
220.127.116.11. Upon determination of the first malfunction of any component or system, 'freeze-frame` engine conditions present at the time must be stored in computer memory. Should a subsequent fuel system or misfire malfunction occur, any previously stored freeze-frame conditions must be replaced by the fuel system or misfire conditions (whichever occurs first). Stored engine conditions must include, but are not limited to calculated load value, engine speed, fuel trim value(s) (if available), fuel pressure (if available), vehicle speed (if available), coolant temperature, intake manifold pressure (if available), closed- or open-loop operation (if available) and the fault code which caused the data to be stored. The manufacturer must choose the most appropriate set of conditions facilitating effective repairs for freeze-frame storage. Only one frame of data is required. Manufacturers may choose to store additional frames provided that at least the required frame can be read by a generic scan tool meeting the specifications of 18.104.22.168 and 22.214.171.124. If the fault code causing the conditions to be stored is erased in accordance with section 3.7 of this Annex, the stored engine conditions may also be erased.
126.96.36.199. If available, the following signals in addition to the required freeze-frame information must be made available on demand through the serial port on the standardized data link connector, if the information is available to the on-board computer or can be determined using information available to the on-board computer: diagnostic trouble codes, engine coolant temperature, fuel control system status (closed-loop, open-loop, other), fuel trim, ignition timing advance, intake air temperature, manifold air pressure, air flow rate, engine speed, throttle position sensor output value, secondary air status (upstream, downstream or atmosphere), calculated load value, vehicle speed and fuel pressure.
The signals must be provided in standard units based on the specifications given in 6.5.3. Actual signals must be clearly identified separately from default value or limp-home signals. In addition, the capability to perform bi-directional diagnostic control based on the specifications given in 6.5.3 must be made available on demand through the serial port on the standardized data link connector according to the specifications given in 6.5.3.
188.8.131.52. For all emission control systems for which specific on-board evaluation tests are conducted (catalyst, oxygen sensor, etc.), except misfire detection, fuel system monitoring and comprehensive component monitoring, the results of the most recent test performed by the vehicle and the limits to which the system is compared must be made available through the serial data port on the standardized data link connector according to the specifications given in 6.5.3. For the monitored components and systems excepted above, a pass/fail indication for the most recent test results must be available through the data link connector.
184.108.40.206. The OBD requirements to which the vehicle is certified (i. e. this Annex or the alternative requirements specified in section 5 of Annex I) and the major emission control systems monitored by the OBD system consistent with 220.127.116.11 must be available through the serial data port on the standardized data link connector according to the specifications given in 6.5.3.
6.5.2. The emission control diagnostic system is not required to evaluate components during malfunction if such evaluation would result in a risk to safety or component failure.
6.5.3. The emission control diagnostic system must provide for standardised and unrestricted access and conform with the following ISO and/or SAE standards. Some of the ISO standards have been derived from Society of Automotive Engineers Standards and Recommended Practices. Where this is the case, the appropriate SAE reference appears in parentheses.
18.104.22.168. One of the following standards with the restrictions as described must be used as the on-board to off-board communications link:
ISO 9141-2 'Road Vehicles - Diagnostic Systems - CARB Requirements for the Interchange of Digital Information`;
ISO 11519-4 'Road Vehicles - Low Speed Serial Data Communication - Part 4: Class B Data Communication Interface (SAE J1850)`. Emission-related messages must use the cyclic redundancy check and the three-byte header and not use inter-byte separation or checksums.
ISO DIS 14230 - Part 4 'Road Vehicles - Diagnostic Systems - Keyword Protocol 2000`.
22.214.171.124. Test equipment and diagnostic tools needed to communicate with OBD systems must meet or exceed the functional specification given in ISO DIS 15031-4.
126.96.36.199. Basic diagnostic data, (as specified in 6.5.1) and bi-directional control information must be provided using the format and units described in ISO DIS 15031-5 and must be available using a diagnostic tool meeting the requirements of ISO DIS 15031-4.
188.8.131.52. When a fault is registered, the manufacturer must identify the fault using the most appropriate fault code consistent with those given in section 6.3 of ISO DIS 15031-6 (SAE J2012 - dated July 1996), relating to '. . . Powertrain system diagnostic trouble codes`. The fault codes must be fully accessible by standardized diagnostic equipment complying with the provisions of 184.108.40.206.
The note in section 6.3 of ISO DIS 15031-6 (SAE J2012 - dated July 1996) immediately preceding the list of fault codes in the same section does not apply.
220.127.116.11. The connection interface between the vehicle and the diagnostic tester must meet all the requirements of ISO DIS 15031-3. The installation position must be subject to agreement of the approval authority such that it is readily accessible by service personnel but protected from tampering by non-qualified personnel.
18.104.22.168. The manufacturer must also make accessible, where appropriate upon payment, to repairers who are not undertakings within the distribution system, the technical information required for the repair or maintenance of motor vehicles unless that information is covered by an intellectual property right or constitutes essential, secret know-how which is identified in an appropriate form; in such case, the necessary technical information must not be withheld improperly.
ESSENTIAL CHARACTERISTICS OF THE VEHICLE FAMILY
1. PARAMETERS DEFINING THE OBD FAMILY
The OBD family may be defined by basic design parameters which must be common to vehicles within the family. In some cases there may be interaction of parameters. These effects must also be taken into consideration to ensure that only vehicles with similar exhaust emission characteristics are included within an OBD family.
2. To this end, those vehicle types whose parameters described below are identical are considered to belong to the same engine-emission control/OBD system combination.
- combustion process (i. e. positive-ignition, compression-ignition, two-stroke, four-stroke),
- method of engine fuelling (i. e. carburettor or fuel injection).
Emission control system:
- type of catalytic converter (i. e. oxidation, three-way, heated catalyst, other),
- type of particulate trap,
- secondary air injection (i. e. with or without),
- exhaust gas recirculation (i. e. with or without)
OBD parts and functioning:
- the methods of OBD functional monitoring, malfunction detection and malfunction indication to the vehicle driver.

Statement by the European Parliament and the Council
Re Article 5a (new)
The European Parliament and the Council take note of the ongoing discussions between the Commission and the European Automobile Manufacturers Association (ACEA) regarding a voluntary undertaking by the industry to reduce the average CO2 emissions from passenger vehicles. The European Parliament and the Council express the hope that the discussions produce an early and acceptable result. They welcome improvements to ACEA's draft commitment since March 1998, but stress the need to resolve ambiguities and outstanding issues at the earliest possible opportunity and in the light of the aim of reducing average passenger car fuel consumption to 120 g of CO2/km.
