This Directive applies to the control of gaseous and particulate pollutants, useful life of emission control devices, conformity of in-service vehicles/engines and on-board diagnostic (OBD) systems of all motor vehicles equipped with compression-ignition engines and to the gaseous pollutants, useful life, conformity of in-service vehicles/engines and on-board diagnostic (OBD) systems of all motor vehicles equipped with positive-ignition engines fuelled with natural gas or LPG, and to compression-ignition and positive-ignition engines ...[+++]as specified in Article 1 with the exception of compression-ignition engines of those vehicles of category N1, N2 and M2 and of positive-ignition engines fuelled with natural gas or LPG of those vehicles of category N1 for which type-approval has been granted under Council Directive 70/220/EEC (1).

9a. For compression‑ignition or gas engines that must comply with the limit values set out in section 6.2.1. of Annex I under the type‑approval system, the following shall apply: under all randomly selected load conditions, belonging to a definite control area and with the exception of specified engine operating conditions which are not subject to such a provision, the emissions sampled during a time duration as small as 30 seconds shall not exceed by more than 100 % the limit values in rows B1, B2 and C of the tables in section 6.2.1. of Annex I. The control area to which the percentage not to be exceeded shall apply and the excluded e ...[+++]ngine operating conditions shall be defined in accordance with the procedure referred to in Article 6.

(1) Directive 97/68/EC implements two stages of emission limit values for compression ignition engines and calls on the Commission to propose a further reduction in emission limits, taking into account the global availability of techniques for controlling air polluting emissions from compression ignition engines and the air quality situation.

From 1 January 2005 for new types and from 1 January 2006 for all types, vehicles of category M1 exempted by Section 8.2, except vehicles of category M1 equipped with compression-ignition engines and the maximum mass of which exceeds 2500 kg, and vehicles in category N1 class 1 equipped with compression-ignition engines, must be fitted with on-board diagnostic (OBD) systems for emission control in accordance with Annex XI.

From 1 January 2006 for new types and 1 January 2007 for all types, vehicles in category N1, classes II and III equipped with compression-ignition engines and vehicles of category M1 equipped with compression-ignition engines and the maximum mass of which exceeds 2500 kg, must be fitted with on-board diagnostic (OBD) systems for emission control in accordance with Annex XI.

8.3. New types of Category M1 exempted by section 8.2, and new types of vehicles in Category N1 class I equipped with compression-ignition engines, must, from 1 January 2005, be fitted with an on-board diagnostic (OBD) system for emission control in accordance with Annex XI. New types of vehicles in Category N1 Classes II and III equipped with compression-ignition engines must, from 1 January 2006, be fitted with on-board diagnostic (OBD) systems for emission control in accordance with Annex XI.
