2 No. Corrigenda Amendment Revision Date Remark Misc. 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. 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.

3 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.

4 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.

5 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.

6 (Including Corrigendum) *As amended by Commission Regulations (EU) 566/2011, 459/2012, 630/2012, 143/2013, 195/2013, 136/2014, 2015/45, 2016/427, (EU) 2016/646, (EU) 2017/1151 and (EU) No. 2017/1221 AIS-137 (Part 3) IV iv) Commission Regulation (EU) 2017/1154 of 7 June 2017 amending Regulation (EU) 2017/1151 supplementing 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)

7 And on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Regulation (EC) No 692/2008 and Directive 2007/46/EC of the European Parliament and of the Council as regards real-driving emissions from light passenger and commercial vehicles (Euro 6) v) UN Regulation 101 (Supplement 6 to the 01 series of amendments. Date of entry into force ) : Uniform provisions concerning the approval of passenger cars powered by an internal combustion engine only, or powered by a hybrid electric power train with regard to the measurement of the emission of carbon dioxide and fuel consumption and/or the measurement of electric energy consumption and electric range, and of categories M1 and N1 vehicles powered by an electric power train only with regard to the measurement of electric energy consumption and electric range vi) Doc.
