标准摘要
[中文适用范围]： 本部分IEC 60068规范了一种复合试验程序，主要用于组件型试样，以确定试样在加速方式下对高温湿度和低温条件破坏性作用的耐受性。本试验标准不适用于在整个试验过程中通电的试样。试样可以在试验的恒定阶段通电。除非另有规定，对通电试样的测量通常是在试验的恒定阶段进行的。 [外文原描述]： 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.
