IEC 60068-2-38:2021作为IEC 60068-2-38:2021 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60068-2-38:2021规定了一种复合材料测试程序，主要用于部件类型样品，以加速方式确定样品对高温/湿度和寒冷条件恶化影响的抵抗力。本试验标准不适用于在整个试验过程中通电的试样。样品可以在测试的恒定阶段通电。除非另有说明，通电试样的测量通常在试验的恒定阶段进行。第三版取消并取代了2009年出版的第二版。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: -数字已更新； -为澄清起见，对措辞作了改动。

IEC 60068-2-38:2021 is available as IEC 60068-2-38:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60068-2-38:2021 specifies a composite test procedure, primarily intended for component type specimens, to determine, in an accelerated manner, the resistance of specimens to the deteriorative effects of high temperature/humidity and cold conditions. This test standard does not apply to specimens that are energized during the complete test. Specimens can be energized during the constant phases of the tests. Measurements on energized specimens are typically carried out during constant phases of the test unless specified otherwise. This third edition cancels and replaces the second edition, published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the figures have been updated;
- changes to the wording has been made for clarification purposes.
