IEC 60068的本部分规定了一种统一且可重复的方法，用于确认温度试验箱符合IEC 60068-2-1和IEC 60068-2-2气候试验程序中规定的要求，当在考虑试验箱工作空间内空气循环的条件下加载散热或非散热试样时。本文件主要供用户在执行以下操作时使用: 定期监测燃烧室性能。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 60068 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 heatdissipating 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.All current amendments available at time of purchase are included with the purchase of this document.
