Scope
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.
Rationale
This standard is intended to provide the industry with a repeatable means of determining the as installed net power and torque of an engine. The current revision has been made to reflect the changing specifications of fuels available in the market place and to clarify issues that experience has shown were unclear in the previous version of the standard.

Issuing Committee
Engine Power Test Code Committee
The Engine Power Test Code Standards Committee reports to the Powertrain Systems Group of the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to the dynamometer testing of internal combustion engines for applications other than marine or aircraft use. Participants in the SAE Engine Power Test Code Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
