本SAE推荐实施规程提供了用于旅行、露营、乘用车、轻型卡车和多用途车辆牵引的船用和轻型多用途拖车上正常公路服务的铁和铝车轮疲劳试验的统一程序和最低性能要求。有关卡车上使用的车轮的程序和最低性能要求，请参见SAE J267；客车上使用的轮胎，请参见SAEJ328。对于客车和轻型卡车车轮（插入小于0.10 m）在拖车服务中的应用，请使用此程序。对于较重卡车车轮（插入0.10 m（或更大））的应用，请使用SAE J267。移动家庭服务不在本文档的范围内。描述了两种基本的试验程序，即转弯疲劳试验和径向疲劳试验。转向测试针对轮盘；而径向测试也检查车轮的轮辋和连接部分。 这两个测试程序都需要对车轮进行彻底检查。

This SAE Recommended Practice provides uniform procedures and minimum performance requirements for fatigue testing ferrous and aluminum wheels intended for normal highway service on travel, camping, and boat and light utility trailers drawn by passenger cars, light trucks, and multipurpose vehicles. For procedures and minimum performance requirements for wheels used on trucks, see SAE J267, and for wheels used on passenger cars, see SAE J328. For the application of passenger car and light truck wheels (inset less than 0.10 m) to this trailer service, use this procedure. For the application of heavier truck wheels (inset 0.10 m (or more)) use SAE J267. Mobile home service is outside the scope of this document.There are two basic test procedures described, a cornering fatigue test and radial fatigue test. The cornering test is directed at the wheel disc; whereas the radial test also examines the rim and attachment portion of the wheel. Both test procedures are required to obtain a thorough examination of the wheel.
