环境试验第3-3部分:支持文件和指南设备的地震试验方法

[中文适用范围]： 本标准适用于电气电子设备，但其应用可扩展至其他设备和零部件。本标准仅涉及可在振动台上进行测试的全尺寸设备的抗震测试。抗震测试旨在证明设备在承受地震产生的应力和位移期间和/或之后执行所需功能的能力。本文件的目的是介绍一系列测试方法，当由相关规范规定时，可应用于证明需要抗震测试的设备的性能，主要目标是实现资格认证。通过所谓“易损性测试”进行的资格认证不认为在本文件范围内，本文件已准备提供抗震测试的通用指导，特别是关于使用IEC 60068-2测试方法的指导。测试方法的选择可根据本文件中描述的准则进行。方法本身紧密基于已发布的IEC测试方法。本文件旨在供制造商用于验证，或供用户用于评估和验证设备的性能。 [外文原描述]： IEC 60068-3-3:2019 applies primarily to electro-technical equipment but its application can be extended to other equipment and to components. In addition, if some type of analysis is always performed when making a seismic qualification, for example for the choice of the representative sample to be tested or for the extension of the seismic qualification from the tested specimen to similar specimens, the verification of the performance of an equipment by analysis or by a combination of testing and analysis can be acceptable but is outside the scope of this document, which is restricted to verification based entirely upon data from dynamic testing. This second edition cancels and replaces the first edition published in 1991. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the main aim of this revision is to connect the testing level to the seismic activity level of the zone where the equipment could be installed; - a standard shape for the required response spectrum is also given for the general seismic class for which the seismic environment is either not known or is imprecisely known; - Clauses 11 to 15 were renumbered and some adjustments were made as their content is very general and the requirements can be applied both to the general seismic class and to the specific seismic class; - the word “envelope” is replaced with “dominance” and “to envelop” with “to dominate” in order to provide a more precise meaning from a mathematical point of view. The contents of the corrigendum of September 2021 have been included in this copy.
