2 Corrigenda Amendment Revision Date Remark Misc. General Remarks: AIS-137 (Part 1) 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. 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.

3 Test procedure for Type Approval and CoP for above emission norms shall be as per various parts of AIS-137, as applicable. This Part 1 of AIS-137 prescribes Test Method, Testing equipment and related procedures for Type Approval and Conformity of Production (COP) Testing of Vehicles of Category L2 having engine Capacity exceeding 50cc and maximum speed exceeding 50 / for BS VI emission norms as per CMV Rules 115, 116 and 126.
