标准摘要
[中文适用范围]： 本部分详细说明了确定光纤互连设备、无源组件、接头或封闭件在运行、存储和/或运输期间承受高温环境条件适用性的程序。该测试旨在指示此类设备在给定时间内暴露于恒温下的性能。一般来说，此测试提供高温以诱导由于软化和膨胀引起的潜在故障。此程序不评估设备在温度变化期间运行的能力；在这种情况下使用IEC61300-2-22。 [外文原描述]： IEC 61300-2-18:2023 details a procedure to determine the suitability of a fibre optic interconnecting device, passive component, splices or closure to withstand the environmental condition of extended high temperature that occur during operation, storage and/or transport. The test is intended to indicate the performance of such devices when exposed to heat of constant temperature over a given period. In general terms, this test provides a high temperature to induce potential failures due to softening and expansions. This procedure does not assess the ability of a device to operate during temperature variations; in this case, IEC 61300-2-22 is used. This third edition cancels and replaces the second edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - terms and definitions updated according to IEC 61753-1:2018; - test severities updated according to IEC 61753-1:2018; - simplification of the combination of temperature and exposure time.
