General Remarks: AIS-137 (Part 3) III INTRODUCTION In India , the mass emission norms based on Indian Driving Cycle (IDC) were notified under CMVR in 1989.

2 The first mass emission norms for vehicles were enforced from 1st April 1991 for Gasoline vehicles and from 1st April 1992 for Diesel vehicles. Since then, progressively emission norms have been tightened. Government of India has notified migration to Bharat Stage VI (BS VI) emissions norms for 2, 3 and 4 wheeled vehicles from 1st April 2020. For Agricultural Tractors, Construction Equipment Vehicles and Combine Harvesters (vehicles having power exceeding 37 kW) next stage emission norms Bharat Stage (CEV/TREM) IV) are notified from 1st October 2020 and Bharat Stage (CEV/TREM) V) from 1st April 2024. Test procedure for Type Approval and CoP for above emission norms shall be as per various parts of AIS-137, as applicable. This Part 3 of AIS-137 prescribes Test Method, Testing Equipment and related procedures for Type Approval and Conformity of Production (COP) Testing of Vehicles of Category M and N having GVW not exceeding 3,500 kg for BS VI emission norms as per CMV Rules 115, 116 and 126.

3 Chapter 20 on Verifying Real Driving Emissions (RDE) will be included after finalized recommendations of the Indian Real Driving Emissions (IRDE) Committee are adopted. While preparing this STANDARD , considerable assistance has been taken from following regulations/documents: i) UN R 83 (Supplement 3 to the 07 series of amendments Date of entry into force: 9 February 2017): Uniform provisions concerning the approval of vehicles with regard to the emission of pollutants according to engine fuel requirements. ii) Regulation (EC) No 715/2007 of The European Parliament and of the Council of 20 June 2007 on type approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information iii) Commission Regulation (EC) No. 692/2008 of July 18, 2008 implementing and amending Regulation (EC) No. 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information.

10 This Part shall apply to vehicles of categories M1, M2, N1 and N2 with a reference mass not exceeding 2,610 kg. At the manufacturer's request, type approval granted under this Part 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 Part. If a vehicle is tested for type approval on chassis dynamometer having reference mass up to 2,610 kg, manufacturer may seek type approval extensions up to reference mass of 2,840 kg for its variants, even if intended variant GVW exceeds beyond 3,500 kg. This Part should be read in conjunction with applicable Gazette Notification for which the vehicle is subjected to test. DEFINITIONS For the purposes of this Part the following definitions shall apply: "Reference mass" means the "unladen mass" of the vehicle increased by a uniform figure of 150kg "Unladen mass" means the mass of the vehicle in running order without the uniform mass of the driver of 75kg, passengers or load, but with the fuel tank 90 % full and the usual set of tools and spare wheel on board, where applicable; Gross Vehicle Weight (GVW) means the technically permissible maximum weight declared by the vehicle manufacturer.
