scope:

Specifies the method of determining the power of RIC engines as equipped when presented for an exhaust emissions test according to ISO 8178. It also specifies the power correction method for the confirmation of engine power for preset engines under variable atmospheric conditions. These corrections do not apply to the definition of the exhaust emission values which are in all cases related to the uncorrected engine power only. Is applicable to RIC engines for land, rail traction and marine use excluding engines for motor vehicles primarily designed for road use. It may be applied to engines used to propel e.g. road construction and earth-moving machines, industrial trucks and for other applications.
