本文件规定了制造商根据SAE J1349（修订版8/04）认证生产发动机的净功率和额定扭矩或根据SAE J1995认证生产发动机的发动机总功率的程序。 宣传其发动机功率和扭矩额定值通过SAE J1349或SAE J1995认证的制造商应遵循本程序。发动机功率和扭矩的SAE J1349或SAE J1995认证是自愿的；然而，对于那些宣传功率等级为“SAE J1349认证”或“SAE J1995认证”的人，此功率认证过程是强制性的。 在由一个制造商制造的发动机在由第二个制造商生产的车辆中出售给消费者的情况下，发动机认证可以由任一制造商或由两个制造商共同完成。后者的一个例子是发动机制造商在车辆制造商提交证明文件的情况下完成见证测试。

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 J1349 (Rev. 8/04) or the gross engine power of a production engine according to SAE J1995. Manufacturers who advertise their engine power and torque ratings as certified to SAE J1349 or SAE J1995 shall follow this procedure. Certification of engine power and torque to SAE J1349 or SAE J1995 is voluntary; however, this power certification process is mandatory for those advertising power ratings as “Certified to SAE J1349” or “Certified to SAE J1995.” 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.
