当需要模拟复杂和混合性质的振动激励时，用于测试样本的一般应用。 试验的目的是证明试样是否足以抵抗规定的混合模式激励，而不会导致其功能和/或结构性能出现不可接受的退化。它特别适用于定制混合模式环境，其中测量数据可用于实际环境。 该试验还有助于揭示随机振动（与正弦和/或随机振动混合）引起的应力累积效应，以及由此产生的机械缺陷和指定性能退化，并结合相关规范，使用该信息评估试样的可接受性。在某些情况下，本标准也可用于证明试样的机械坚固性。 本标准适用于可能受到运输或现实生活环境中产生的随机和/或随机和确定性组合振动的试样，例如飞机、航天器及其运输容器中的物品，如果后者可能被视为试样本身的一部分。 尽管本标准主要用于电工试样，但不限于此类试样，并可在需要时用于其他领域。 具有符合IEC指南104的基本安全出版物的状态。

Intended for general application for testing specimens when simulation is required of vibration excitation of a complex and mixed nature. The purpose of the test is to demonstrate the adequacy of the specimen to resist the specified mixed mode excitation without unacceptable degradation of its functional and/or structural performance. It is particularly useful for tailoring mixed mode environments where measured data are available for the real life environment. The test also helps reveal the accumulated effects of stress induced by random vibration, mixed with sine and/or random, and the resulting mechanical weakness and degradation in specified performances, and to use this information, in conjunction with the relevant specification, to assess the acceptability of specimens. In some cases, this standard may also be used to demonstrate the mechanical robustness of specimens. This standard is applicable to specimens which may be subjected to vibration of a random and/or a combination of random and deterministic nature resulting from transportation or real life environments, for example in aircraft, space vehicles and for items in their transportation container when the latter may be considered as part of the specimen itself. Although primarily intended for electrotechnical specimens, this standard is not restricted to such specimens and may be used in other fields where desired. Has the status of a basic safety publication in accordance with IEC Guide 104.
