This standard specifies the durability requirements (including measurement methods) for vehicle adopted with compression ignition engine and that adopted with the spark ignition engine fuelled with natural gas (NG) or liquefied petroleum gas (LPG) as well as emission control system of such engines.
This standard is applicable to the type approval of the emission control system of compression ignition (including gas fuelled positive ignition) engines equipped in M2, M3, N1, N2 and N3 vehicles with design speed greater than 25 km/h as well as M1 vehicles with total mass greater than 3,500kg.
Where N1 and M2 vehicles adopted with compression ignition (including gas fuelled positive ignition) engines meet the durability requirements of "Limits and Measurement Methods for Emissions from Light-duty Vehicles" (GB 18352.3-5), this standard may not be implemented.
