Reciprocating internal combustion engines — Exhaust emission measurement — Part 4: Test cycles for different engine applications

Specifies the test cycles for the measurement and the evaluation of gaseous and particulate exhaust emissions from reciprocating internal combustion engines coupled to a dynamometer. With some restrictions the test can also be used for measurements at site. Applies to engines for mobile, transportable and stationary use, excluding engines for motor vehicles primarily designed for road traffic.
