标准摘要
[中文适用范围]： 本部分IEC 60721涉及IEC 60721-3-3中给出的条件与IEC 60068-2中定义的环境测试程序的相关性和转换。 本文件为在静止天气保护位置运行的电工设备提供了测试程序和测试严重性，适用于IEC 60721-3-3中规定的产品类别。 环境可以包括多种环境条件，如动态、气候、生物以及由于化学和机械活性物质引起的其他影响。本文件中考虑了动态、气压、生物和气候条件。 本文件的目的是为规范编写者提供指导，并提供一组易于使用的表格，用于关联和转换这些环境条件。 [外文原描述]： IEC TS 60721-4-3:2023 This part of IEC 60721 deals with the correlation and transformation of the conditions given in IEC 60721-3-3 to the environmental test procedures defined in IEC 60068-2. This document provides test procedures and test severities for electrotechnical equipment operated at stationary weatherprotected locations for the product classes set out in IEC 60721-3-3. This first edition cancels and replaces IEC TR 60721-4-3:2001 and IEC TR 60721-4-3:2001/AMD1:2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TR 60721-4-3:2001 and IEC TR 60721-4-3:2001/AMD1:2003: a) the document has been totally reworked; b) all figures have been removed, except in Annex A; c) severities have been aligned with those of IEC 60721-3-3:2019.
