Scope

The standard specifies the in-service vehicle / engine conformity requirements of
automobile equipped with compression ignition engine and its compression ignition
engine, the spark ignition engine automobile and its spark ignition engine with NG or LPG
as fuel.
This standard applies to the in-service vehicle / engine conformity inspection of M2, M3, N1,
N2 and N3 classes of vehicles whose designing speed are larger than 25km/h; and M1
class vehicle equipped with compression ignition engines (including gas fuelled positive
ignition type) and its automobile whose total mass is larger than 3500kg.
If the N1 and M2 classes of vehicles equipped with compression ignition engines (including
gas fuelled positive ignition type) engine have been conducted the conformity inspection
of in-service vehicle according to the standards of GB 18352.3-2005 Limits and
Measurement Methods for Light Car Pollutant Emission (China III, IV stage), it doesn’t have to
perform this standard.
