ISO 8178

ISO 8178 is a collection of steady state test cycles used for defining emission standards for non-road engines in the European Union, United States, Japan and other countries. Test cycle ISO 8178 C1 is also referred to as "Non-Road Steady Cycle" and used extensively. The is supplementing it in some modern emission standards.

It is defined by the International Organization for Standardization (ISO).
