标准摘要
[中文适用范围]： IEC 61300 的这一部分详细介绍了确定光纤设备或闭合件是否适合承受操作、储存和/或运输期间可能出现的湿度和温度变化的程序。该测试旨在表明此类设备在暴露于高温和潮湿环境并随后短暂冷冻时的性能。一般来说，该测试提供高温以诱发因软化和膨胀而引起潜在故障，高湿度以促进吸湿和膨胀，以及低温以促进冰形成、脆化和收缩。该测试与其他循环环境测试不同，特别是 IEC 61300-2-46 的湿热循环测试和 61300-2-21 的复合温度-湿度循环测试，通过合并替代的严重程度。这是通过a）更多的循环次数来实现的； b) 更大的循环温度范围； c) 循环周期缩短。 [外文原描述]： IEC 61300-2-48:2009 details a procedure for determining the suitability of a fibre optic device or closure to withstand variations in humidity and temperature that may occur during operation, storage and/or transport. The test is intended to indicate the performance of such devices when exposed to heat and humidity followed by short-term freezing. The main changes to this second edition are the addition of the Category O cycle procedure and the severity reconsideration.
