适用范围:This part of ISO 8178, together with ISO 8178-1 and ISO 8178-11, specifies the measurement and evaluationmethods for gaseous and particulate exhaust emissions from reciprocating internal combustion engines (RICengines) under steady-state and transient conditions for field testing.This part of ISO 8178 is applied when RIC engines used in off-road vehicles, marine installations, generatingsets, diesel rail traction or similar applications need to be measured under field conditions or at site in order todetermine the in-use compliance, or when it is not possible to take the measurements under test-bedconditions or to use the test-bed measurement results.Re-checking or re-certification of engines for off-road vehicles after rebuild should preferably be tested outsidethe vehicle on a suitable load application and measurement device such as a dynamometer or load bank, butin-use compliance testing may be done on the vehicle.This method can be used for determining conformity or certification of new, used or rebuilt engines at site orfor in-use compliance testing of off-road vehicles. Confirmation of test-bed results with respect to ISO 8178-4can also be performed within this part of ISO 8178. However, allowances need to be made for differences inengine operating parameters from laboratory conditions and for the accuracy of emission measurementequipment used under field conditions.For engines used in machinery covered by additional requirements (e.g. occupational health and safetyregulations, regulations for powerplants), additional test conditions and special evaluation methods may apply.NOTE This part of ISO 8178 is intended to specify special requirements for the measurement of gaseous andparticulate emissions at site or under field operating conditions. In many cases, the test cycles specified in ISO 8178-4 andISO 8178-11 cannot be reproduced at site due to constraints of load. For in-use compliance testing, actual in-useoperation might be required.
