SAE J2723_200708

This document specifies the procedure to be used for a manufacturer to certify the net power and torque rating of a production engine according to SAE J 1349 (Rev. 8/04) or the gross engine power of a production engine according to SAE J 1995.

Manufacturers who advertise their engine power and torque ratings as Certified to SAE J 1349 or SAE J 1995 shall follow this procedure. Certification of engine power and torque to SAE J 1349 or SAE J 1995 is voluntary, however, this power certification process is mandatory for those advertising power ratings as "Certified to SAE J 1349".

In the event that an engine made by one manufacturer is sold to a consumer in a vehicle produced by a second manufacturer, engine certification may be completed by either manufacturer or by both manufacturers working together. An example of the latter would be the completion of witness testing by the engine manufacturer with the submission of certification documents by the vehicle manufacturer.
