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 engine1 ScopeThis 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.2 Normative referencesThe contents of this standard refer to the following documents or their terms. For undated references, the valid version applies to this standard. GB 3847-2005 Limits and measurement methods for exhaust smoke from C.I.E. (compression ignition engine) and vehicle equipped with C.I.E. GB 20891-2007 Limits and measurement methods for exhaust pollutants from diesel engines of non-road mobile machinery (I, II)3 Terms and definitionsThe following terms and definitions apply to this standard. 3.1 Non-road mobile machinery equipped with diesel engine For non-road types of machinery as mentioned in the “Scope”, that is. 3.2 Onboard diesel engine equipment A diesel-powered vehicle-mounted dedicated device that is used on a vehicle for carrying people (goods) on the road and that does not provide driving force for the vehicle. 3.3 Rated net power (Pmax) The net power which is indicated by the manufacturer, according to the provisions of GB 20891-2014, for the diesel engine when the information is disclosed. 3.4 Coefficient of light adsorption The coefficient by which the beam is attenuated by the smoke per unit length, in units of m-1. 3.5 Smoke opacimeter An instrument which is used for continuously measuring the coefficient of light absorption of exhaust of diesel engine as specified in GB 3847. principle of Ringelmann smoke method as specified in Appendix B.4 Limit of exhaust smoke4.1 Perform testing of exhaust smoke in accordance with clause 5.The opacity smoke (coefficient of light absorption) and the Ringelmann number of the exhaust from non-road mobile machinery equipped with diesel engine shall not exceed the limits as specified in Table 1. 4.1.1 The non-road mobile machinery equipped with diesel engine for the phase II and previous phase as specified in GB 20891-2007 implements the category I limits as provided in Table 1. 4.1.3 The Municipal People's Government may, according to the atmospheric environment quality, delineate and publish the areas that prohibit the use of high-emission non-road mobile machinery equipped with diesel engines. 4.2 The limits of opacity smoke (coefficient of light adsorption) of the exhaust from different kinds of non-road mobile machinery equipped with diesel engine which is used in areas above 1700 m altitude shall be increased by 0.25 m-1 based on the values as provided in Table 1.5 Testing methods5.1 Testing conditions of smoke 5.1.1 Before the testing of smoke, the diesel engine of the machinery under testing shall be fully preheated. During the continuous testing of the machinery, it shall ensure that the engine is in normal working condition. 5.2 Testing method of smoke 5.2.1 Opacity smoke method Use the smoke opacimeter to continuously measure the coefficient of light adsorption of the exhaust from the non-road mobile machinery equipped with diesel engines, under the operating conditions of 5.1.The sampling frequency shall be not lower than 1 Hz. Take the maximum reading of the opacimeter in the measuring process as the measuring result. 5.2.2 Ringelmann smoke method For the non-road mobile machinery equipped with diesel engines, use the Ringelmann smoke method specified in Appendix B to continuously observe the exhaust smoke under the measurement conditions as described in 5.1.6 Decision rules6.1 If the Lingerman smoke of the non-road mobile machinery equipped with diesel engine exceeds the standard, the exhaust smoke testing is judged to be unqualified. 6.2 For non-road mobile machinery equipped with diesel engine qualified by Ringelmann smoke testing, the competent department of ecology and environment may continue to use the opacity smoke method to conduct on-site testing of the exhaust smoke.7 Management requirements7.1 The manufacturing enterprise shall, in accordance with the requirements of this standard, formulate the self-examination procedures, conduct self-testing of the newly-produced machinery, disclose the self-testing results. 7.3 In accordance with the requirements of the Municipal People's Government for the areas to ban the use of high-emission non-road mobile machinery equipped with diesel engines, it may use such methods as registration and installation of positioning systems, to strengthen the tracking management.8 Requirements of testing instruments8.1 The working principle and accuracy of the emission testing equipment (smoke opacimeter, etc.) shall meet the relevant requirements of GB 3847.9 Requirements of testing fuel9.1 When performing the on-site testing of the exhaust smoke from non-road mobile machinery equipped with diesel engines, it shall not replace the in-use fuel of the non-road mobile machinery equipped with diesel engines.10 Testing reportThe testing report of the exhaust smoke from the non-road mobile machinery equipped with diesel engines shall meet the requirements of Appendix A. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
