The manufacturer shall implement adequate arrangements and documented control plans and carry-out at specified intervals as given in this regulation the necessary emission and OBFCM tests to verify continued conformity with the approved type. The approval authority shall verify and agree with these arrangements and control plans of the manufacturer and perform audits and conduct emission and OBFCM tests at specific intervals, as given in this regulation, at the premises of the manufacturer, including production and test facilities as part of the product conformity and continued verification arrangements as described in Annex IV of Regulation (EU) 2018/858.

4.1.2.

The manufacturer shall check the conformity of production by testing the emissions of pollutants (given in Table 1 of Annex I to Regulation (EU) 2024/1257), the emission of CO2 (along with the measurement of electric energy consumption and, where applicable, the monitoring of the OBFCM device accuracy), the crankcase emissions and evaporative emissions in accordance with the test procedures described in Annexes V, VI, XXI and XXII. The verification shall therefore include the tests of types 1, 3, 4 and the tests for OBFCM, as described in Section 2.2. The approval authority shall keep record for a period of at least 5 years of all the documentation related to the conformity of production test results and shall make it available to the Commission upon request. The specific procedures for conformity of production are set out in paragraphs 8 and 9 and Appendices 1 to 5 of UN Regulation No 154. The calculation of values required for checking the Conformity of Production of electric energy consumption of PEVs and OVC-HEVs is set out in Appendix 8 of Annex B8 to UN Regulation No 154.

4.1.3.

In case of non-conformity Article 51 of Regulation (EU) 2018/858 shall apply.

4.2.

Vehicles fitted with eco-innovations

4.2.1.

In the case of a vehicle type with regard to emissions fitted with one or more eco-innovations, within the meaning of Article 11 of Regulation (EU) 2019/631 (10) for M1 or for N1 vehicles, the conformity of production shall be demonstrated with respect to the eco-innovations, by checking the presence of the correct eco-innovation(s) in question.

4.3.

Checking the conformity of the vehicle for a Type 3 test

If a verification of the Type 3 test is to be carried out, it shall be conducted in accordance with the following requirements:

4.3.1.

When the approval authority determines that the quality of production seems unsatisfactory, a vehicle shall be randomly taken from the family and subjected to the tests described in Annex V.

4.3.2.

The production shall be deemed to conform if this vehicle meets the requirements of the tests described in Annex V.

4.3.3.

If the vehicle tested does not satisfy the requirements of the tests described in Annex V, a further random sample of four vehicles shall be taken from the same family and subjected to the tests described in Annex V. The tests may be carried out on vehicles which have completed a maximum of 15 000 km with no modifications.

IN-SERVICE CONFORMITY METHODOLOGY

1.   INTRODUCTION

This Annex sets out the in-service conformity (ISC) methodology for checking compliance against the emission limits for tailpipe (including low temperature) and evaporative emissions throughout the additional lifetime of the vehicle, as set out in Table 1 of Annex IV to Regulation (EU) 2024/1257.

2.   GENERAL REQUIREMENTS

The general requirements for conducting in-service conformity testing set out in Article 10 apply.

3.   TECHNICAL REQUIREMENTS

The technical requirements for conducting in-service conformity testing shall be those set out in Annex 4 of UN Regulation No 83 (1) with the exceptions described in the points below.

3.1.

The Process Description in section 2 shall read as follows:

2   PROCESS DESCRIPTION:

Figure 1

Illustration of the in-service conformity process

(where GTAA refers to the granting type-approval authority, OEM refers to the manufacturer, and Other Actors are defined as: TAA refers to approval authorities other than the one granting the relevant type-approval, TS refer to technical services, EC to the Commission, and recognised third parties that meet the requirements laid down in Regulation (EU) 2022/163  (2))

3.2.

The first 3 paragraphs of section 5 shall read as follows: ‘5.   ISC TESTING The manufacturer shall perform ISC testing for tailpipe emissions comprising at least the Type 1 test for all ISC families. The manufacturer may also perform RDE, ATCT, Type 4 and Type 6 tests for all or part of the ISC families. The manufacturer shall report to the granting type-approval authority all results of the ISC testing using the Electronic Platform for in-service conformity described in point 5.9, or other appropriate means where this is not possible. The granting type-approval authority shall check an appropriate number of ISC families each year, as set out in point 5.4. The manufacturer shall include all results of the ISC testing in the Electronic Platform for in-service conformity described in point 5.9. Recognised third parties may perform checks on any number of ISC families each year. They shall report to the granting type-approval authority all results of the ISC testing using the Electronic Platform for in-service conformity described in point 5.9, or other appropriate means where this is not possible.’

3.3.

The first paragraph of section 5.7.1 shall read as follows: ‘5.7.1.   General requirements The vehicle shall belong to an ISC family as described in point 3 and shall comply with the checks set out in the table in Appendix 1. It shall be registered in the Union and have been driven in the Union for at least 90 % of its driving time. The emissions testing may be done in a different geographical region from that where the vehicles have been selected. In case of ISC testing conducted by the manufacturer, with the agreement of the granting type-approval authority, vehicles registered in a non-EU country or vehicles which have been registered in the EU but are temporarily de-registered may be tested, if they belong to the same ISC family and are accompanied by a certificate of conformity.’

3.4.

The final paragraph of section 5.7.1 shall read as follows: ‘A vehicle shall be excluded from ISC testing if the fuel from the vehicle tank does not meet the applicable standards laid down in Directive 98/70/EC of the European Parliament and of the Council (*1) or if there is evidence or record of fuelling with the wrong type of fuel. (*1)  Directive 98/70/EC of the European Parliament and of the Council of 13 October 1998 relating to the quality of petrol and diesel fuels (OJ L 350, 28.12.1998, p. 58, ELI: http://data.europa.eu/eli/dir/1998/70/oj).’ "

3.5.

Section 5.8 shall read as follows: ‘5.8.   Sample size When manufacturers apply the statistical procedure set out in point 5.10 for the Type 1 test, the number of sample lots shall be set on the basis of the annual sales volume of an in-service family in the Union, as described in the following table: Table 1 Number of sample lots for ISC testing with Type 1 tests Registrations in the EU per calendar year of vehicles in the sampling period Number of sample lots (for Type 1 tests) up to 100 000 1 100 001 to 200 000 2 above 200 000 3 Each sample lot shall include enough vehicle types (with regard to emissions), in order to ensure that at least 20 % of the total registrations of this PEMS family in the EU for the previous year are covered. In case the same PEMS family is shared between more brands, then all brands shall be tested. When a family requires more than one sample lot to be tested, the vehicles selected in the second and third sample lots shall have been used in different ambient and/or typical use conditions from those selected for the first sample.’

3.6.

Section 5.9 above Table A4/2 shall read as follows: ‘5.9.   Use of the Electronic Platform for in-service conformity and access to data required for testing The Commission has set up an electronic platform in order to facilitate the exchange of data between on the one side, the manufacturers, other actors and on the other side the granting type-approval authority and the taking of the decision on the sample fail or pass.

ANNEX IV

MANIPULATION DEVICES AND MANIPULATION STRATEGIES

1.   INTRODUCTION

1.1.

This Annex sets out the tests, methods and procedures for establishing the absence of manipulation devices and manipulation strategies as construed under Article 4(5) of Regulation (EU) 2024/1257 and in accordance with manufacturers’ obligations under Article 4 of the same Regulation.

1.2.

This Annex also specifies the documentation that ensures the proper monitoring and enforcement of rules related to manipulation devices and manipulation strategies. It aims to strengthen emissions control mechanisms, enhance transparency, and ensure that vehicles comply with regulatory requirements for the lifetime of the vehicles, particularly Euro 7 exhaust emission and evaporative emission limits under the conditions set out in Annex III of Regulation (EU) 2024/1257, as well as the prohibition of manipulation devices and manipulation strategies.

1.3.

Specifications for methodologies, tests and procedures that relate to data integrity, such as manipulation of data related to sensors, fuel or electric energy consumption, electric range or battery durability, are provided for in Implementing Regulation (EU) 2025/1707.

1.4.

This Annex also sets out roles and responsibilities for the actors involved to ensure compliance with the above-mentioned regulatory requirements and prohibition of manipulation devices and manipulation strategies.

1.5.

For the purposes of this Annex, manipulation devices and manipulation strategies should be construed as set out by Article 3(41) and 3(42) of Regulation (EU) 2024/1257. The notion of manipulation strategy shall be distinguished from respectively the notions of ‘Base Emission Strategies (BES)’ and ‘Auxiliary Emission Strategies (AES)’ which are defined in respectively Article 2(17) and 2(18) of this Regulation, and which relate to documentation requirements under this Annex.

2.   GENERAL REQUIREMENTS – TESTS AND METHODOLOGIES

2.1.

Referring to the provisions of Articles 3(41) and 3(42) of Regulation (EU) 2024/1257, (i) manipulation devices and manipulation strategies related to emissions (exhaust, evaporative or other); and (ii) manipulation devices and manipulation strategies related to data integrity should be distinguished.

2.2.

When assessing situations that could involve the use of manipulation devices or manipulation strategies for exhaust and evaporative emissions, a broad assessment and interpretation of those situations should be made. Any devices or strategies that reduce the effectiveness of exhaust and non-exhaust emission limits and testing condition requirements under this Regulation, that cause a non-compliant vehicle to appear compliant or that falsify test results, should be considered when determining whether manipulation devices or manipulation strategies exist. Market surveillance authorities should apply dedicated screening tests and enforcement measures to prevent the circumvention of Euro 7 requirements.

2.3.

The assessment of such situations as part of type-approval should distinguish and identify specific situations where the reduction of effectiveness of exhaust and evaporative emission control (1) is justified by technical reasons and is not due to manipulation. This is particularly relevant in driving conditions that are adjacent to one or more boundary conditions of a regulated emissions test. For such situations, manufacturers shall comply with criteria for the declaration of technically justified emission control strategies that are only active for a specific set of ambient or operating conditions, thereby documenting and explaining the reduction of the effectiveness of emission control that may be observed (for instance, the dosing of reagent may stop at very low temperatures due to physical limitations of hardware). These technically justified emission strategies shall satisfy strict criteria to demonstrate that they are acceptable and that therefore they do not constitute a manipulation device or manipulation strategy as defined in Regulation (EU) 2024/1257, without prejudice to the requirements set out in Article 4(2) of the same Regulation. The methodology for the assessment and approval of AES is specified in Appendix 1 to this Annex.

2.4.

Manufacturers shall ensure that no vehicle is equipped with manipulation devices or strategies related to data integrity as defined in paragraphs 41 and 42 in Article 3 of Regulation (EU) 2024/1257.

2.5.

Manufacturers shall not introduce software or calibration updates that manipulate data related to sensors, fuel or electric energy consumption, electric range or battery durability, either before or after the placing in the market.

2.6.

Manufacturers shall disclose any software and calibration updates affecting the integrity of data related to sensors, fuel or electric energy consumption, electric range or battery durability to the granting type-approval authority.

3.   TECHNICAL REQUIREMENTS – DOCUMENTATION

3.1.

Manufacturers shall document Auxiliary Emission Strategies (AES) at type-approval. The procedure of assessing AES ensures the consistent approval of elements of design or actions, in line with Article 14(7) of Regulation (EU) 2024/1257. For the type-approval authorities to be able to assess the proper use of AES, considering the prohibition of manipulation devices and manipulation strategies contained in Article 4(5) of Regulation (EU) 2024/1257, the manufacturer shall provide an extended documentation package, as described in Appendix 1 to this Annex.

3.2.

The extended documentation shall remain strictly confidential. It may be kept by the approval authority, or, at the discretion of the approval authority, may be retained by the manufacturer. In the case the manufacturer retains the documentation package, that package shall be identified and dated by the approval authority once reviewed and approved. It shall be made available for inspection by the approval authority at the time of approval or at any time during the validity of the approval.

3.3.

Manufacturers shall also provide to the approval authorities a formal documentation package, as described in Appendix 2 to this Annex, containing information on AES/BES that would allow an independent tester to identify if the emissions measured can be attributed to an AES or BES strategy or are potentially due to a manipulation device or manipulation strategy.

3.4.

Manufacturers shall make the formal documentation package available to all type-approval authorities, technical services, market surveillance authorities, recognised third parties and the Commission upon request.

3.5.

Manufacturers shall introduce an indicator (AES flag or timer) to indicate when a vehicle runs in a mode where an AES that has been documented in the extended documentation package is active instead of BES mode. The indicator shall be available via the serial port of the standard diagnostic connector upon request of a generic scan-tool. The AES that is running shall be identifiable via the formal documentation package.

4.   ROLES AND RESPONSIBILITIES

4.1.

This paragraph sets out roles and responsibilities for the actors involved to ensure compliance with regulatory requirements: — For vehicle manufacturers: it introduces criteria for the declaration of justified auxiliary emission control strategies that are active for a specific purpose and in response to a specific set of ambient or operating conditions. These emission control strategies shall satisfy strict technical criteria to demonstrate that they do not constitute a manipulation device or manipulation strategy as defined in Regulation (EU) 2024/1257. — For type-approval authorities: it introduces criteria for the approval of technically justified emission control strategies. The approval of such emission control strategies relies on the concept of ‘Auxiliary Emission Strategies’ (AES), which is adapted from the Euro 6 legal framework. This Annex supports the documentation of AES and clarifies their role in aiding emissions measurement and monitoring through on-board monitoring systems (OBM). — For market surveillance authorities: it sets a framework for the detection of manipulation devices and manipulation strategies using dedicated screening tests and enforcement measures to prevent the circumvention of Euro 7 requirements. — For recognised third parties and the European Commission: it sets out roles in the performance of screening tests.

4.2.

Roles and responsibilities of vehicle manufacturers

4.2.1.

Manufacturers shall ensure the absence of manipulation devices and manipulation strategies related to emissions under the scope of this Regulation: manufacturers shall ensure that no vehicle is equipped with manipulation devices or strategies as defined in paragraphs 41 and 42 in Article 3 of Regulation (EU) 2024/1257.

4.2.2.

Manufacturers shall document software updates to vehicles in service that reduce the effectiveness of emissions control strategies after type-approval.

4.2.3.

Manufacturers shall disclose any software updates or calibrations affecting exhaust emissions control systems to the granting type-approval authority.

4.2.4.

Manufacturers shall document Auxiliary Emission Strategies (AES) as part of type-approval as specified in paragraph 3 ‘Technical requirements – documentation’.

4.2.5.

The manufacturer shall cooperate with the type-approval authority to allow them to select up to a maximum of 5 AES that will be monitored by OBM according to Annex I of Implementing Regulation (EU) 2025/1707.

4.3.

Roles and responsibilities of type-approval authorities

4.3.1.

At the request of the manufacturer, the approval authority shall conduct a preliminary assessment of the AES for new vehicle types with regard to emissions, together with the selection of AES according to paragraph 4.2.5. In that case, the relevant documentation shall be provided to the type-approval authority between 2 and 12 months before the start of the type-approval process.

4.3.2.

The type-approval authority shall make a preliminary assessment based on the extended documentation package, as described in point (b) of Appendix 2 to this Annex, provided by the manufacturer. The approval authority shall make the assessment in accordance with the methodology described in Appendix 1 to this Annex. The type-approval authority may deviate from that methodology in exceptional and duly justified cases.

4.3.3.

The preliminary assessment of the AES for new vehicle types with regard to emissions shall remain valid for the purposes of type-approval for a period of 18 months. That period may be extended by the type-approval authority by a further 12 months at the request of the manufacturer.

4.3.4.

In cooperation with the manufacturer, the type-approval authority shall select up to a maximum of 5 AES that will be monitored by OBM according to Annex I of Implementing Regulation (EU) 2025/1707. The selection of AES shall prioritise those AES with the greatest expected impact by combination of their effect upon emissions when they are active and their expected rate of activation while the vehicles are in use.

4.3.5.

The extended documentation package shall be identified and dated by the type-approval authority. If the extended documentation package is kept by the type-approval authority, it shall be retained for at least 10 years after the approval is granted.

4.3.6.

The type-approval authority shall evaluate the documentation of software updates that reduce the effectiveness of emissions control strategies after type-approval and extend the approval as appropriate as long as the requirements continue to be met.

4.3.7.

The type-approval authority may test the functionality of the AES flag or timer to indicate when a vehicle runs in AES mode instead of BES mode.

4.3.8.

Type-approval authorities shall ensure a harmonised assessment of Auxiliary Emission Strategies (AES). A list of AES which were deemed non-acceptable by type-approval authorities shall be compiled yearly by the Forum for Exchange of Information on Enforcement and made available to the public by the Commission at the latest by end of March of the following year, in case there were AES which were deemed non-acceptable by the Forum.

4.4.

Roles and responsibilities of market surveillance authorities

4.4.1.

Market surveillance authorities may conduct screening tests to detect manipulation devices and manipulation strategies related to emissions.

4.4.2.

Market surveillance authorities should decide case-by-case which methods are best suited, based on an appropriate risk assessment which considers possible non-compliance, the likelihood of its occurrence, and other possible indicators, like the severity of the occurrence.

4.4.3.

The search for manipulation devices or strategies could include two distinct cases:   Case A) ‘Boundary detection’: manipulation devices or strategies that use the regulated test boundaries or surrogates thereof as triggers (such as ambient temperature, altitude, trip duration, fuel consumed and driving dynamics ranges); or   Case B) ‘Test detection’: manipulation devices or strategies triggered by the presence of test equipment (e.g. backpressure increase at the tailpipe, signals on rear ultrasonic sensors, connection of a data recorder on the OBD port) or the vehicle localization (i.e. anything informing the vehicle that it is being tested on road for tailpipe emissions). These ‘Test detection’ manipulation devices or manipulation strategies apply primarily to on-road tests with PEMS, since vehicles tested in the laboratory usually need to use a special ‘chassis dynamometer mode’ to allow emissions testing without triggering safety devices, etc.

4.4.4.

For all screening test campaigns, it shall be necessary, as a minimum, to include testing the vehicle with the regulatory methodologies. This is an important step to make sure that the vehicle is free of malfunctioning, poor maintenance or other similar issues, which would unduly increase the level of emissions.

4.4.5.

To detect the presence of manipulation devices or strategies according to Case A, it is necessary that the vehicles are tested under variations of the regulated testing conditions referred to as ‘modalities’. The set of modalities is not fixed but instead kept open due to the need to detect specific technology behaviours in response to a complex set of parameters and the need to keep an unpredictable character.

4.4.6.

Market surveillance authorities shall enforce the prohibition of manipulation devices and manipulation strategies related to emissions. If a manipulation device or strategy related to emissions is identified, market surveillance authorities shall proceed in accordance with Chapter XI of Regulation (EU) 2018/858.

4.4.7.

Market surveillance authorities shall ensure a uniform application of criteria for the assessment of screening tests by having regard to the latest version of the relevant non-binding guidance published by the European Commission and to the information available within the Forum for Exchange of Information on Enforcement.

4.5.

Roles and responsibilities of the Commission and recognised third parties

4.5.1.

The Commission and recognised third parties may conduct screening tests to detect manipulation devices and manipulation strategies related to emissions according to paragraph 4.4.1.

Appendix 1

Methodology for the assessment and approval of AES and BES

This appendix provides a structured approach for assessing and approving Auxiliary Emission Strategies (AES) and Base Emission Strategies.

1.   Documentation of AES and BES

1.1.

Manufacturers shall include a technical description of their BES in the extended documentation package according to Appendix 2.

1.2.

Manufacturers shall document all AES, with the possible omission of certain AES according to paragraph 1.5. Manufacturers shall justify the use of an AES that is documented based on one or more of the following criteria: (a) The AES is necessary for the safe operation of the vehicle. (b) The AES is necessary to avoid sudden and irreparable damage to a powertrain (1) component. (c) The AES is only active during engine start. (d) The AES is necessary due to physical limitations of the emission control system.

1.3.

For each AES that is documented, manufacturers shall submit: — A description of the technical motivation for the AES. This will be substantiated by supporting evidence, such as durability tests or risk analyses, demonstrating why the AES is technically necessary; — A description of the precise conditions that lead to the activation and de-activation of the AES. This shall include, as appropriate, engine parameters, ambient parameters and any other relevant condition; — An estimation of the emissions and CO2 impact of the AES when it is active; — An estimation of the expected rate of activation of the AES while the vehicles are in use.

1.4.

The information referred to in paragraph 1.3 shall be included in the extended documentation package according to Appendix 2.

1.5.

Manufacturers may omit any AES from the extended documentation package provided they meet one or more of the following conditions: — The AES does not lead to the exceedance of limit values defined in Annex I of Regulation (EU) 2024/1257 while it is active; — The AES does not reduce the effectiveness of the emission control systems while it is active; — The conditions that lead to the activation of the AES are substantially included in the test procedures.

2.   Assessment of AES and BES

2.1.

Authorities shall approve a BES that satisfies the documentation requirements of paragraph 1.1.

2.2.

Authorities shall approve an AES that is documented if it is technically justified by one or more criteria under paragraph 1.2, provided that the following criteria are also met: — The technical motivation for the AES is satisfactory and supported by appropriate evidence; — The conditions that lead to the activation and de-activation of the AES are set according to technical characteristics of the emission control systems concerned and not to the boundary conditions or other conditions covered by a regulatory test.

3.   Approval of AES and BES

The type-approval authority shall approve the AES and BES submitted by the manufacturer based on the contents of the extended documentation package.

The extended documentation package shall be limited to 100 pages.

The extended documentation package may be complemented with annexes and other attached documents, containing additional and complementary elements, if necessary. The manufacturer shall send a new consolidated version of the extended documentation package (with tracked changes) to the type-approval authority every time changes are introduced to the AES. The new version of the AES shall be evaluated and approved by the type-approval authority.

The extended documentation package shall include a declaration of the software versions and calibrations used to control these AES/BES, including the appropriate checksums or reference values of these software versions and calibrations, as well as instructions to the authority on how to read the checksums or reference values; the declaration shall be updated and sent to the type-approval authority that holds this extended documentation package each time there is a new software version or calibration that has an impact on the AES/BES. Manufacturers may request to use an alternative to a checksum if it provides an equivalent level of traceability for software version and calibration management.

The extended documentation package shall also include a declaration of the manufacturer on the absence of manipulation devices or manipulation strategies. The approval of the extended documentation package shall not constitute proof of the absence of manipulation devices or manipulation strategies.

These values shall be fed into the calculation tool to determine the CO2 emissions and fuel consumption of the completed vehicle.

2.3.

By way of derogation from paragraph 2.1, where the base vehicle is a complete vehicle, the final-stage manufacturer shall determine the CO2 emissions of the completed vehicle on the basis of information from the base vehicle manufacturer. The CO2 emissions shall be determined in accordance with the CO2 interpolation method using the appropriate data from the completed vehicle or calculated on the basis of the parameters of the completed vehicle as specified in paragraph 3.2.4 of Annex B7 to UN Regulation No 154 and using the calculation tool referred to in point 2.2 if it is supplied by the base vehicle manufacturer. If the CO2 interpolation is not possible or the tool is not available, subject to the agreement of the approval authority, the CO2 emissions of the completed vehicle shall be the CO2 emissions of Vehicle High from the base vehicle.

2.4.

The final-stage manufacturer shall include in the certificate of conformity the information of the completed vehicle and the information of the base vehicle in accordance with Regulation (EU) 2020/683. In the case of multi-stage vehicles submitted to individual vehicle approval, the individual approval certificate shall include the following information: (a) the CO2 emissions measured in accordance with the methodology set out in point 2.1 or, where applicable, 2.2 or 2.3; (b) the mass in running order of the completed vehicle; (c) the type, variant and version of the base vehicle; (d) the type-approval number of the base vehicle; (e) the name and address of the base vehicle manufacturer; (f) the mass in running order of the base vehicle.

The requirements for the type-approval of replacement pollution control devices shall be those of Section 5 of UN Regulation No 103 with the exceptions set out in sections 4.1.1 to 4.1.4.

4.1.1.

Reference to the ‘test cycle’ in Section 5 of UN Regulation No 103 shall be understood as being the same Type 1 test and Type 1 test cycle as used for the original type-approval of the vehicle.

4.1.2.

The terms ‘catalytic converter’ and ‘converter’ used in section 5 of UN Regulation No 103 shall be understood to mean ‘pollution control device’.

4.1.3.

The regulated pollutants referred to throughout section 5.2.3 of UN Regulation No 103 shall be replaced by all the pollutants specified in Annex 1, Table 1 of Regulation (EU) 2024/1257 for replacement pollution control devices intended to be fitted to vehicles type approved to Regulation (EU) 2024/1257.

4.1.4.

For replacement pollution control devices intended to be fitted to vehicles type approved to Regulation (EU) 2024/1257, the durability requirements and associated deterioration factors specified in section 5 of UN Regulation No 103, shall refer to those specified in Annex VII to this Regulation.

4.2.

For vehicles with positive-ignition engines, if the NMHC emissions measured during the demonstration test of a new original equipment catalytic converter, under paragraph 5.2.1 of UN Regulation No 103, are higher than the values measured during the type-approval of the vehicle, the difference shall be added to the OBD thresholds. The OBD thresholds are specified in Table 4A of paragraph 6.8.2 of UN Regulation No 154.

4.3.

The revised OBD thresholds will apply during the tests of OBD compatibility set out in paragraphs 5.5 to 5.5.5 of UN/ECE Regulation No 103. In particular, when the exceedance allowed in paragraph 1 of Appendix 1 to Annex C5 to UN Regulation No 154 is applied.

4.4.

Requirements for replacement periodically regenerating systems

4.4.1.

Requirements regarding emissions

4.4.1.1.

The vehicle(s) indicated in Articles 13(3), (4) and (5), equipped with a replacement periodically regenerating system of the type for which approval is requested, shall be subject to the tests described in Appendix 1 to Annex B6 to UN Regulation No 154, in order to compare its performance with the same vehicle equipped with the original periodically regenerating system.

4.4.1.2.

Reference to the ‘Type 1 test’ and ‘Type 1 test cycle’ in Appendix 1 to Annex B6 to UN Regulation No 154 and the ‘test cycle’ in Section 5 of UN Regulation No 103 shall be understood as being the same Type 1 test and Type 1 test cycle as used for the original type-approval of the vehicle.

4.4.2.

Determination of the basis for comparison

4.4.2.1.

The vehicle shall be fitted with a new original periodically regenerating system. The emissions performance of this system shall be determined following the test procedure set out in Appendix 1 to Annex B6 to UN Regulation No 154.

4.4.2.1.1.

Reference to the ‘Type 1 test’ and ‘Type 1 test cycle’ in Appendix 1 to Annex B6 to UN Regulation No 154 and the ‘test cycle’ in Section 5 of UN Regulation No 103 shall be understood as being the same Type 1 test and Type 1 test cycle as used for the original type-approval of the vehicle.

4.4.2.2.

Upon request of the applicant for the approval of the replacement component, the approval authority shall make available on a non- discriminatory basis, the information referred to in point 3.2.12.2.10.2 of the information document contained in Annex A1 of UN Regulation No 154 for each vehicle tested.

4.4.3.

Exhaust gas test with a replacement periodically regeneration system

4.4.3.1.

The original equipment periodically regenerating system of the test vehicle(s) shall be replaced by the replacement periodically regenerating system. The emissions performance of this system shall be determined following the test procedure set out in Appendix 1 to Annex B6 to UN Regulation No 154.

4.4.3.1.1.

Reference to the ‘Type 1 test’ and ‘Type 1 test cycle’ in Appendix 1 to Annex B6 to UN Regulation No 154 and the ‘test cycle’ in Section 5 of UN Regulation No 103 shall be understood as being the same Type 1 test and Type 1 test cycle as used for the original type-approval of the vehicle.

4.4.3.2.

To determine the D-factor of the replacement periodically regenerating system, any of the engine test bench methods referred to in Appendix 1 to Annex B6 to UN Regulation No 154 may be used.

4.4.4.

Other requirements The requirements provided in paragraphs 5.2.3, 5.3, 5.4 and 5.5 of UN Regulation No 103 shall apply to replacement periodically regenerating systems. In these paragraphs the words ‘catalytic converter’ shall be understood to mean ‘periodically regenerating system’. The exceptions provided in the paragraphs in section 4.1 of this Annex shall also apply to periodically regenerating systems.

5.   DOCUMENTATION

5.1.

Each replacement pollution control device shall be clearly and indelibly marked with the manufacturer’s name or trade mark and accompanied by the following information: (a) the vehicles (including year of manufacture) for which the re- placement pollution control device is approved, including, where applicable, a marking to identify if the replacement pollution control device is suitable for fitting to a vehicle that is equipped with an on-board diagnostic (OBD) system; (b) installation instructions, where necessary. The information shall be available in the product catalogue distributed to points of sale by the manufacturer of replacement pollution control devices.

6.   CONFORMITY OF PRODUCTION

6.1.

Measures to ensure the conformity of production shall be taken in accordance with the provisions laid down in Article 31 of Regulation (EU) 2018/858.

6.2.

Special provisions

6.2.1.

The checks referred to in point 3 of Annex IV to Regulation (EU) 2018/858 shall include compliance with the characteristics as defined under Article 3(5) of this Regulation.

6.2.2.

For the application of Article 31(3) of Regulation (EU) 2018/858, the tests described in section 4.4.1 of this Annex and section 5.2 of UN/ECE Regulation No 103 (requirements regarding emissions) may be carried out. In this case, the holder of the approval may request, as an alternative, to use as a basis for comparison not the original equipment pollution control device, but the replacement pollution control device which was used during the type-approval tests (or another sample that has been proven to conform to the approved type). Emissions values measured with the sample under verification shall then on average not exceed by more than 15 % the mean values measured with the sample used for reference.
