标准摘要
[中文适用范围]： 本部分IEC 60068规定了一种统一且可重复的方法，用于确认温度试验箱在考虑工作空间内空气循环的条件下，装载散热或不散热样品时，符合IEC 60068-2-1和IEC 60068-2-2中规定的气候试验程序的要求。本文件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 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
