Scope This Regulation establishes technical requirements for the type approval of motor vehicles. In addition, this Regulation lays down rules for in-service conformity, durability of pollution control devices and On-Board Diagnostic (OBD) systems.

6 This Regulation shall apply to vehicles of categories M1, M2, N1 and N2 with a reference mass not exceeding 2,610 At the manufacturer's request, type approval granted under this Regulation may be extended from vehicles mentioned above to M1, M2, N1 and N2 vehicles with a reference mass not exceeding 2,840 kg and which meet the conditions laid down in this Regulation. 2. Definitions For the purposes of this Regulation the following definitions shall apply: "Vehicle type" means a group of vehicles that do not differ in the following respects: The equivalent inertia determined in relation to the reference mass as prescribed in Table A4a/3 of Annex 4a to this Regulation; and The engine and vehicle characteristics as defined in Annex 1 to this Regulation. "Reference mass" means the unladen mass of the vehicle increased by a uniform figure of 100 kg for test according to Annexes 4a and 8 to this Regulation.

7 "Unladen mass" means the mass of the vehicle in running order without the uniform mass of the driver of 75 kg, passengers or load, but with the fuel tank 90 per cent full and the usual set of tools and spare wheel on board, where applicable. "Running order mass" means the mass described in paragraph of Annex 1 to this Regulation and for vehicles designed and constructed for the carriage of more than 9 persons (in addition to the driver), the mass of a crew member (75 kg), if there is a crew seat amongst the nine or more seats. "Maximum mass" means the technically permissible maximum mass declared by the vehicle manufacturer (this mass may be greater than the maximum mass authorised by the national administration). "Gaseous pollutants" means the exhaust gas emissions of carbon monoxide, oxides of nitrogen expressed in nitrogen dioxide (NO2) equivalent and hydrocarbons assuming ratio of: (a) for Liquefied Petroleum Gas (LPG); 1 As defined in the Consolidated Resolution on the Construction of Vehicles ( ), document ECE/ , para.

8 2. - E/ECE/324 E/ECE/TRANS/505 6 (b) C1H4 for Natural Gas (NG) and biomethane; (c) for petrol (E5); (d) for petrol (E10); (e) for diesel (B5); (f) for diesel (B7); (g) for ethanol (E85); (h) for ethanol (E75). "Particulate pollutants" means components of the exhaust gas which are removed from the diluted exhaust gas at a maximum temperature of 325 K (52 C) by means of the filters described in Appendix 4 to Annex 4a to this Regulation. "Particulate numbers" means the total number of particulates of a diameter greater than 23 nm present in the diluted exhaust gas after it has been conditioned to remove volatile material, as described in Appendix 5 to Annex 4a to this Regulation. "Exhaust emissions" means: (a) For Positive ignition ( ) engines, emissions of gaseous and particulate pollutants; (b) For Compression-Ignition ( ) engines, emissions of gaseous pollutants, particulate pollutants and particulate numbers.

9 "Evaporative emissions" means the hydrocarbon vapours lost from the fuel system of a motor vehicle other than those from exhaust emissions. "Tank breathing losses" are hydrocarbon emissions caused by temperature changes in the fuel tank (assuming a ratio of ). "Hot soak losses" are hydrocarbon emissions arising from the fuel system of a stationary vehicle after a period of driving (assuming a ratio of C1 ). "Engine crankcase" means the spaces in or external to an engine which are connected to the oil sump by internal or external ducts through which gases and vapour can escape. "Cold start device" means a device that temporarily enriches the air/fuel mixture of the engine thus assisting the engine to start. "Starting aid" means a device which assists engine start up without enrichment of the air/fuel mixture of the engine, glow plug, injection timing change, etc.

10 "Engine capacity" means: For reciprocating piston engines, the nominal engine swept volume. For rotary piston engines (Wankel), twice the nominal swept volume of a combustion chamber per piston. "Pollution control devices" means those components of a vehicle that control and/or limit exhaust and evaporative emissions. "On-Board Diagnostic (OBD)" means an on-board diagnostic system for emission control, which has the capability of identifying the likely area of malfunction by means of fault codes stored in computer memory. E/ECE/324 E/ECE/TRANS/505 7 "In-service test" means the test and evaluation of conformity conducted in accordance with paragraph of this Regulation. "Properly maintained and used" means, for the purpose of a test vehicle, that such a vehicle satisfies the criteria for acceptance of a selected vehicle laid down in paragraph 2.
