scope:

Specifies the measurement and evaluation methods for gaseous and particulate exhaust emission from recoprocating internal combustion engines (RIC engines) under steady-state conditions on a test bed, necessary for determining one weighted value for each exhaust gas polluant. Various combinations of engine load and speed reflect different engine applications. This part of ISO 8178 is applicable to RIC engines for mobile, transportable and stationary use, excluding engines for motor vehicles primarily designed for road use. This part of ISO 8178 may be applied to engines used e.g. in earth-moving machines, generating sets and other applications.
