scope:

This part of ISO 3046 summarizes the common measurement techniques of the main performance parameters of reciprocating internal combustion engines to ensure that the required accuracy of measurement is achieved for comparison of the measured values with those values specified by the engine manufacturer. Where necessary, individual requirements may be given for particular engine applications.

It applies to reciprocating internal combustion engines for land, rail-traction and marine use, excluding engines used to propel agricultural tractors, road vehicles and aircraft.

It may be applied to engines used to propel road construction and earth-moving machines, industrial trucks and for other applications where no suitable International Standards for these engines exist.
