Scope

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 25km/h as well as M1 vehicles with total mass greater than 3500kg.
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 18352.3−2005, this standard may not be implemented.
