本SAE推荐规程为卡车、公共汽车、载重汽车挂车和多用途车辆上正常公路使用的车轮和可拆卸轮辋的疲劳试验提供了最低性能目标和统一的实验室程序。用户可以制定超过最低性能目标的设计标准，以增加对设计的信心。表1和表2中注明的周期目标基于威布尔统计，使用两个参数，中值秩、50%置信水平和90%可靠性，β等于2，通常标注为B10C50。对于乘用车、轻型卡车和多用途车辆上正常公路使用和临时使用的其他车轮，请参阅SAE J328。对于乘用车、轻型卡车或多用途车辆牵引的挂车上使用的车轮，请参阅SAE J1204。有关用螺栓连接的军用车轮，请参阅SAE J1992。本文件不包括其他特殊应用车轮和轮辋。

This SAE Recommended Practice provides minimum performance target and uniform laboratory procedures for fatigue testing of wheels and demountable rims intended for normal highway use on trucks, buses, truck-trailers, and multipurpose vehicles. Users may establish design criteria exceeding the minimum performance target for added confidence in a design. The cycle target noted inTables 1and2are based on Weibull statistics using two parameter, median ranks, 50% confidence level and 90% reliability, and beta equal to two, typically noted as B10C50. For other wheels intended for normal highway use and temporary use on passenger cars, light trucks, and multipurpose vehicles, refer to SAE J328. For wheels used on trailers drawn by passenger cars, light trucks, or multipurpose vehicles, refer to SAE J1204. For bolt together military wheels, refer to SAE J1992. This document does not cover other special application wheels and rims.
