5. REQUIREMENTS

5.1. General requirements

5.1.1. The replacement catalytic converter shall be designed, constructed and capable of being mounted so as to enable the vehicle to comply with the provisions of those Regulations which it was originally in compliance with and that pollutant emissions are effectively limited throughout the normal life of the vehicle under normal conditions of use.

5.1.2. The installation of the replacement catalytic converter shall be at the exact position of the original equipment catalytic converter, and the position on the exhaust line of the oxygen probe(s), if applicable, shall not be modified.

5.1.3. If the original equipment catalytic converter includes thermal protections, the replacement catalytic converter shall include equivalent protections.

5.1.4. The replacement catalytic converter shall be durable, that is designed, constructed and capable of being mounted, so that reasonable resistance to the corrosion and oxidation phenomena to which it is exposed is obtained, having regard to the conditions of use of the vehicle.

5.2. Requirements regarding emissions

The vehicle(s) indicated in paragraph 3.3.1 of this Regulation, equipped with a replacement converter of the type for which approval is requested, shall be subjected to a type I test under the conditions described in the corresponding annexes of Regulation No 83 in order to compare its performance with the original catalytic converter according to the procedure described below.

5.2.1. Determination of the basis for comparison

The vehicle(s) shall be fitted with a new original catalytic converter (see paragraph 3.3.1) which shall be run in with 12 extra urban cycles (test type I part 2). After this preconditioning, the vehicle(s) shall be kept in a room in which the temperature remains relatively constant between 293 and 303 K (20 and 30 °C). This conditioning shall be carried out for at least six hours and continue until the engine oil temperature and coolant, if any, are within ± 2 K of the temperature of the room. Subsequently three exhaust gas tests type I shall be made.

5.2.2. Exhaust gas test with replacement catalytic converter

The original catalytic converter of the test vehicle(s) shall be replaced by the replacement catalytic converter (see paragraph 3.3.2) which shall be run in with 12 extra urban cycles (test type I part 2). After this preconditioning, the vehicle(s) shall be kept in a room in which the temperature remains relatively constant between 293 and 303 K (20 and 30 °C). This conditioning shall be carried out for at least six hours and continue until the engine oil temperature and coolant, if any, are within ± 2 K of the temperature of the room. Subsequently three exhaust gas tests type I shall be made.

5.2.3. Evaluation of the emission of pollutants of vehicles equipped with replacement catalytic converters

The test vehicle(s) with the original catalytic converter shall comply with the limit values according to the type approval of the vehicle(s) including - if applicable - the deterioration factors applied during the type approval of the vehicle(s).

The requirements regarding emissions of the vehicle(s) equipped with the replacement catalytic converter shall be deemed to be fulfilled if the results meet for each regulated pollutant (CO, HC + NOx and particulates) the following conditions:

1. M <= 0,85 S + 0,4 G

2. M <= G

where:

M: mean value of the emissions of one pollutant (CO or particulates) or the sum of two pollutants (HC + NOx) obtained from the three type I tests with the replacement catalytic converter

S: mean value of the emissions of one pollutant (CO or particulates) or the sum of two pollutants (HC + NOx) obtained from the three type I tests with the original catalytic converter

G: limit value of the emissions of one pollutant (CO or particulates) or the sum of two pollutants (HC + NOx) according to the type approval of the vehicle(s) divided by - if applicable - the deterioration factors determined in accordance with paragraph 5.4 below.

Where approval is applied for different types of vehicles from the same car manufacturer, and provided that these different types of vehicles are fitted with the same type of original equipment catalytic converter, the type I testing may be limited to at least two vehicles selected after agreement with the technical service responsible for approval.

5.3. Requirements regarding noise and vehicle performance

The replacement catalytic converter shall satisfy the technical requirements of Regulation No 59. As an alternative to the measurement of back-pressure as specified in Regulation No 59, the verification of the vehicle performance can be performed by measuring on a chassis dynamometer the maximum absorbed power at a speed corresponding to the engine maximum power. The value determined under reference atmospheric conditions as specified in Regulation No 85 with the replacement catalytic converter shall not be lower by more than 5 per cent than that determined with the original equipment catalytic converter.

5.4. Requirements regarding durability

The replacement catalytic converter shall comply with the requirements of paragraph 5.3.5 of Regulation No 83, i.e. type V test or deterioration factors from the following table for the results of the type I tests.

>TABLE>

6. MODIFICATION OF THE REPLACEMENT CATALYTIC CONVERTER TYPE AND EXTENSION OF APPROVAL

Every modification of the replacement catalytic converter type shall be notified to the administrative department which approved this type of replacement catalytic converter.

The department may then either:

(i) consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the replacement catalytic converter still complies with the requirements, or

(ii) require a further test report for some or all the tests described in paragraph 5 of this Regulation from the technical service responsible for conducting the tests.

Confirmation or refusal of approval, specifying the alteration, shall be communicated by the procedure specified in paragraph 4.3 above to the Parties to the Agreement applying this Regulation.

The competent authority issuing the extension of approval shall assign a serial number to each communication form drawn up for such an extension.

7. CONFORMITY OF PRODUCTION

The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev. 2), with the following requirements.

7.1. The replacement catalytic converters approved under this Regulation shall be so manufactured as to conform to the type approved in the characteristics as defined under paragraph 2.3 of this Regulation.

They shall meet the requirements set forth in paragraph 5 and, where applicable, fulfil the requirements of the tests specified in this Regulation.

7.2. The approval authority may carry out any check or test prescribed in this Regulation. In particular, the tests described in paragraph 5.2 of this Regulation (requirements regarding emissions) may be carried out. In this case, the holder of the approval may ask, as an alternative, to use as a basis for comparison not the original equipment converter, but the replacement catalytic converter 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 per cent the mean values measured with the sample used for reference.

8. PENALTIES FOR NONCONFORMITY OF PRODUCTION

8.1. The approval granted in respect of a type of replacement catalytic converter pursuant to this Regulation may be withdrawn if the requirements laid down in paragraph 7 above are not complied with.

8.2. If a Party to the Agreement which applies this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation, by means of a form conforming to the model in annex 1 to this Regulation.

9. PRODUCTION DEFINITIVELY DISCONTINUED

If the holder of the approval completely ceases to manufacture a type of replacement catalytic converter approved in accordance with this Regulation, he shall so inform the authority which granted the approval.

Upon receiving the relevant communication, that authority shall inform thereof the other Parties to the Agreement applying this Regulation by means of a form conforming to the model in annex 1 to this Regulation.

10. NAMES AND ADDRESSES OF TECHNICAL SERVICES RESPONSIBLE FOR CONDUCTING APPROVAL TESTS, AND OF ADMINISTRATIVE DEPARTMENTS
