本SAE航空航天推荐规程（ARP）确立了测试机身滑动轴承的方法。ARP5448及其相关斜线表的目的是记录通常用于评估机身轴承的试验方法。当试验被认为适合轴承最终用户对轴承的预期用途时，这些试验方法可在规范、零件标准、采购订单等中引用。这些试验方法并不打算涵盖机身轴承的所有可能要求。轴承的最终用户必须进行工程判断，以确定应用的最合适标准和/或非标准测试。

This SAE Aerospace Recommended Practice (ARP) establishes methods for testing airframe plain bearings. The purpose of ARP5448 and its associated slash sheets is to document test methods commonly used to evaluate airframe bearings. These test methods may be referenced in specifications, part standards, purchase orders, etc., when the test is deemed appropriate to the intended use of the bearing by the end user of the bearing. These test methods are not intended to encompass every conceivable requirement for an airframe bearing. The end user of the bearing must exercise engineering judgment to determine the most appropriate standard and/or nonstandard tests for the application.
