IEC 60068-3-3:20 19主要适用于电气技术设备，但其应用可以扩展到其他设备和组件。此外，如果在进行抗震鉴定时总是执行某种类型的分析，例如用于选择待测试的代表性样品或用于将抗震鉴定从测试样本扩展到类似样本，则通过分析或通过测试和分析的组合来验证设备的性能是可以接受的，但超出了本文档的范围，本文档仅限于完全基于动态测试数据的验证。这第二版取消并取代了1991年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-这一修订的主要目的是将测试水平与可能安装设备的区域的地震活动水平联系起来； -对于地震环境未知或不精确已知的一般地震类别，也给出了所需反应谱的标准形状； -第11至15条重新编号，并作出一些调整，因为其内容非常笼统，规定既适用于一般地震类别，也适用于特定地震类别； -将“包络”一词替换为“支配”，将“包络”替换为“支配”，以便从数学角度提供更精确的含义。

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.
