This part of ISO 8178 specifies as a standard data format for reporting the measurement results of exhaust emissions from 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. earth-moving machines, generating sets and for other applications. This part of ISO 8178 applies to measurement in the laboratory and at site.

For engines used in machinery covered by additional requirements, (e.g. occupational health and safety regulations, dust regulations for powerplants) additional test conditions and special evaluation methods may apply.
