标准摘要
[中文适用范围]： 本部分IEC 60068规定了确认温度试验箱符合IEC 60068-2-1和IEC 60068-2-2气候试验程序要求的统一且可重复的方法，当试验箱在考虑工作空间内空气循环的条件下装载散热或不散热试样时。本文档主要供用户在进行定期箱体性能监测时使用。 [外文原描述]： IEC 60068-3-7:2020 specifies a uniform and reproducible method of confirming that temperature test chambers conform to the requirements specified in the climatic test procedures of IEC 60068-2-1 and IEC 60068-2-2, when loaded with either heat-dissipating or non heat-dissipating specimens under conditions which take into account air circulation inside the working space of the chamber. This document is intended primarily for users when conducting regular chamber performance monitoring. This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - verbal forms have, in many parts, been changed to express requirements instead of recommendations ('shall' instead of 'should'); - Table 1 has been updated.
