IEC 61300-2-18:20 23 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 61300-2-18:20 23详细说明了确定光纤互连设备、无源组件、接头或封闭件是否适合承受操作、储存和/或运输过程中出现的长期高温环境条件的程序。该测试旨在指示此类器械在给定时间段内暴露于恒温热时的性能。一般来说，该测试提供了高温，以诱导由于软化和膨胀而导致的潜在故障。本程序不评估器械在温度变化期间的工作能力；在这种情况下，使用IEC 61300-2-22。这第三版取消并取代了2005年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: -根据IEC 61753-1:20 18更新的术语和定义； -根据IEC 61753-1:20 18更新测试严重性； -简化温度和暴露时间的组合。

IEC 61300-2-18:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

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.
