Scope

ISO 8178-9:2012 specifies the measurement procedures and test cycles for the evaluation of smoke emissions from compression ignition engines on the test bed.
For transient smoke test cycles, smoke testing is conducted using smokemeters which operate on the light extinction principle. The purpose of ISO 8178-9:2012 is to define the smoke test cycles and the methods used to measure and analyse smoke. Specifications for measurement of smoke using the light extinction principle can be found in ISO 11614.
