GB 18352.6-2016/XG1-2026 Limits and measurement methods for emissions from light-duty vehicles(CHINA 6)，includes Amendment 1
1 Scope
This standard is applicable to the light-duty vehicles, including hybrid electric vehicles, powered by positive-ignition engines or compression-ignition engines, with a maximum design speed 50 km/h.
This standard specifies the limits and measurement methods for exhaust emissions at normal and low temperatures, real driving emissions (RDE), crankcase emissions, evaporative emissions and refueling emissions, and technical requirements and measurement methods for the durability of pollution control devices and on-board diagnostic (OBD) systems of light-duty vehicles equipped with positive-ignition engines.
This standard specifies the limits and measurement methods for exhaust emissions at normal and low temperatures, real driving emissions and crankcase emissions, and technical requirements and measurement methods for the durability of pollution control devices and on-board diagnostic (OBD) systems of light-duty vehicles equipped with compression-ignition engines.
This standard specifies the requirements and method for type test of light-duty vehicles, check requirements and determination methods of conformity of production and in-service conformity.
This standard also specifies the special requirements for vehicles fuelled with liquefied petroleum gas (LPG) or natural gas (NG).
This standard also specifies the type test procedure for replacement pollution control devices as separate technical units intended to be fitted on light-duty vehicles with respect to pollutant emissions.
This standard also stipulates the technical requirements for vehicles that use a reagent for the exhaust after-treatment system and the procedure for emission test of vehicles equipped with periodically regenerating systems.
At the manufacturer's request, type test may be performed for Category M1, M2 and N2 vehicles with the maximum mass >3,500kg but 4,500kg in accordance with this standard.
If a vehicle covered by this standard has passed the type test in accordance with GB 17691 (China VI), such vehicle may be exempted from type test according to this standard.
The light-duty vehicles fuelled by the fuel types that are not contained in Annex K shall also comply with the requirements of this standard.
