GB 36886-2018Limits and measurement methods for exhaust smoke from non-road mobile machinery equipped with diesel engine (English PDF)

Foreword

In order to implement the "Environmental protection law of the People's

Republic of China" and the "Air pollution control law of the People's Republic of

China", to prevent and control the environmental pollution caused by particulate

matter discharged from non-road mobile machinery equipped with diesel

engines, this standard is hereby formulated.

This standard specifies the limits and measurement methods for exhaust

smoke from non-road mobile machinery equipped with diesel engine. This

standard applies to the testing of the exhaust smoke from non-road mobile

machinery equipped with diesel engine and on-board diesel equipment. The

inspection of the exhaust smoke from the newly-produced and imported non-

road mobile machinery equipped with diesel engine may make reference to this

standard.

This standard refers to and adopts the relevant technical contents of the

European Commission Directive 77/537/EEC "Directive on the approximation

of the laws of the member States relating to the measures to be taken against

the emission of pollutants from diesel engines for use in wheeled agricultural or

forestry tractors" and GB 3847 "Limits and measurement methods for emissions

form diesel vehicles under free acceleration and lugdown cycle".

Appendix A and Appendix B of this standard are normative appendixes.

This standard is the first release.

This standard was formulated under the organization of the Department of

Atmospheric Environment, Department of Regulations and Standards of the

Ministry of Ecology and Environment.

Main drafting organizations of this standard. Beijing Institute of Technology,

Jinan Automobile Testing Center Co., Ltd.

This standard was approved by the Ministry of Ecology and Environment on

September 27, 2018.

This standard shall be implemented since December 01, 2018.

From the date of implementation of this standard, all relevant local standards

shall be abolished.

For this standard, the Ministry of Ecology and Environment is responsible for

the interpretation.

Limits and measurement methods for

exhaust smoke from non-road mobile

machinery equipped with diesel engine

1 Scope

This standard specifies the limits and measurement methods for exhaust

smoke from non-road mobile machinery equipped with diesel engine and

onboard diesel equipment.

This standard applies to the testing of the exhaust smoke from non-road mobile

machinery equipped with diesel engine and on-board diesel equipment. The

inspection of the exhaust smoke from the newly-produced and imported non-

road mobile machinery equipped with diesel engine may make reference to this

standard.

This standard applies to the following (including but not limited to) non-road

mobile machinery equipped with diesel engines which is operated at non-

constant speeds.

- Construction machinery (including loaders, excavators, bulldozers, road

rollers, asphalt pavers, forklifts, off-highway trucks, etc.);

- Agricultural machinery;

- Forestry machinery;

- Material handling machinery;

- Industrial drilling exploration equipment;

- Snow plow equipment;

- Airport ground service equipment.

This standard applies to the following (including but not limited to) non-road

mobile machinery equipped with diesel engines which is operated at constant

speed.

- Air compressor;

- Power generator set;

- Fishing machinery;

- Water pump.
