标准摘要
[中文适用范围]： IEC 60068-2-30:2025标准规定了一项试验程序，用于评定元件、设备或其他物品在高湿度结合循环温度变化条件下（通常导致试件表面产生冷凝）的适用性，以及其运输和储存的适宜性。该试验方法也可用于验证试件在运输和储存过程中的包装有效性。本第四版取代并作废于2005年发布的第三版，属于技术性修订。与前一版相比，本版本主要包含以下技术变更：a) 修订了试验室的要求；b) 调整了试验的温度容差限值；c) 更新了部分图示以作澄清说明；d) 修订了预处理阶段温度及相对湿度的限值；e) 修订了中间测量要求；f) 修订了试验报告的标准要求。 [外文原描述]： IEC 60068-2-30:2025 specifies a test procedure to determine 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. This test method can also be used to validate the packaging of specimen for transportation and storage. This fourth edition cancels and replaces the third edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) revision of the requirements for the test chamber; b) change of the temperature tolerances of the test to limits; c) updating of the figures for clarification purposes; d) revision of the limits of the temperature and relative humidity during conditioning; e) revision of the intermediate measurements; f) revision of standardized requirements for the test report.
