确定部件、设备或其他物品在高湿度条件下使用、运输和储存的适用性——结合循环温度变化，通常在试样表面产生冷凝。如果试验用于验证在包装中运输或储存试样时的性能，则在应用试验条件时，通常会安装包装。 对于较小、质量较低的试样，使用该程序可能难以在试样表面产生冷凝；用户应该考虑使用替代程序，例如IEC 600 682-38。 与上一版相比，主要变化如下: - 编辑修改， -添加规范性引用文件， -增加了温度公差指南， -恢复期已经延长。 具有符合IEC指南104的基本安全出版物的状态。

Determines the suitability of components, equipment or other articles for use, transportation and storage under conditions of high humidity - combined with cyclic temperature changes and, in general, producing condensation on the surface of the specimen. If the test is being used to verify the performance of a specimen whilst it is being transported or stored in packaging then the packaging will normally be fitted when the test conditions are being applied. For small, low mass specimens, it may be difficult to produce condensation on the surface of the specimen using this procedure; users should consider the use of an alternative procedure such as that given to IEC 60068-2-38. The main changes with respect to the previous edition are listed below: - editorial changes, - addition of normative references, - addition of guidance for temperature tolerances, - period for recovery has been extended. Has the status of a basic safety publication in accordance with IEC Guide 104.
