ISO 6460-2:2014定义了测量摩托车废气排放量的试验循环，以及ISO 3833中定义的测定配备火花点火发动机（四冲程发动机、二冲程发动机或旋转活塞发动机）或压燃式发动机的摩托车燃油消耗量的试验循环。试验循环1相当于欧盟委员会指令2003/77/EC[6]中规定的试验循环，试验循环2相当于联合国欧洲经济委员会ECE/TRANS/180/Add.第2号全球技术法规（WMTC）中规定的试验循环。2[9]. 附录C中描述了几个国家已采用或将采用的其他试验循环的选择，以供参考。

ISO 6460-2:2014 defines test cycles for measurement for the gaseous exhaust emissions from motorcycles, as well as for determining the fuel consumption of motorcycles as defined in ISO 3833, equipped with a spark ignition engine (four-stroke engine, two-stroke engine, or rotary piston engine) or a compression ignition engine. The test cycle 1 is equivalent to the test cycle specified in the European Union Commission Directive 2003/77/EC[6] and the test cycle 2 is equivalent to the test cycle specified in global technical regulations No.2 (WMTC), United Nations Economic Commission for Europe, ECE/TRANS/180/Add.2[9]. A selection of other test cycles adopted or to be adopted by several countries is described in Annex C for information purpose.
