INTRODUCTIONDOC.NO.: MoRTH/CMVR/TAP-115-116Issue No. 4This document prescribes the test method, testing equipment and otherrelated procedure for the purpose of testing motor vehicles for verifying compliance toRule 115 and 126A of CMVR for Type Approval and Conformity of Production. Thisdocument covers Bharat Stage-I,II, III & IV norms for 2-wheeler, 3-wheeler and motorcars and diesel engines wherever applicable, Trem-II, Trem-III & Trem IIIA norms foragriculture, power tiller and emission norms for construction equipment vehicles.[Concerned G.S.R. Notification nos. are 493(E), 77(E), 284(E), 286(E), 675(E),788(E), 853(E), 83(E), 686(E), 720(E),589(E),276(E),84(E)]. This also contains thetotal procedure for checking of the in-service vehicles for idling CO/HC for vehiclesfitted with petrol / CNG / LPG engines or free acceleration smoke for vehicles fittedwith diesel engines.The emission regulation limits will be as notified by MoRTH under CMVR from time totime.This document is at present divided into 15 parts.Parts I and II are the procedures for checking idling CO and HC, free accelerationsmoke on in-service petrol / diesel vehicles. These are based on which are originallyintended for the type-approval for rule 115(2).Parts III, IV and V covers the test procedure for rules 115(3), (4) and (5) respectively,which are Annexure III, IV and V of Ranganathan Committee Report, incorporatingsome changes as
measurement of carbon monoxide and hydro carbon emissions at idling for in-service vehicles fitted with engines 14 II -- Details of standards and test procedures for measurement of smoke levels by free acceleration for in-service vehicles fitted with diesel engines 18 III -- Details of standards for emission of gaseous pollutants from petrol engined vehicles and test procedures effective from .
