This SAE Standard has been adopted to provide a basis for dynamometer determination of gross engine power and torque under reference conditions. It is intended for use primarily by engine manufacturers who supply engines for installation by others in applications where the engine manufacturer may not control the induction and exhaust system design or the speed at which the engine is run.

This standard is intended to provide a method to obtain repeatable measurements that accurately reflect true engine performance in customer service. Whenever there is an opportunity for interpretation of the standard, a good faith effort shall be made to obtain the engine’s typical in-service performance and avoid finding the best possible performance under the best possible conditions. Intentional biasing of engine component or assembly tolerances to optimize performance for this test is prohibited.
