本SAE推荐规程提供了测量方法的测试程序、要求和设备建议，这些测量方法通过利用阶跃应力法使被测装置承受超出其在实际使用中可能看到的类型和水平的热应力、振动应力和电应力来表征潜在的设计故障，但这些应力会迅速诱发故障模式，允许他们被检测和纠正。

This SAE Recommended Practice provides test procedures, requirements, and equipment recommendations for the methods of the measurement that characterizes potential design failures by utilizing a step stress approach to subject a device under test to thermal, vibration, and electrical stresses of types and levels beyond what it may see in actual use, but which will rapidly induce failure modes, allowing them to be detected and corrected.
