光纤. 第1-53部分: 测量方法. 水浸渍试验

[中文适用范围]： IEC 60793 的这一部分提供了在特定环境中评估光纤性能的实用方法。本标准的目的是定义一项测试，以确定 A1a 至 A1d 子类多模光纤以及 B 类和 C 类单模光纤承受实际使用中可能出现的蒸馏水或软化水浸泡环境条件的适用性@ 储存和/或运输。该测试的主要目的是观察给定时间内浸入水中的影响。该程序根据 IEC 60068-2-18@ 测试 R 进行。 注：该测试对其他光纤类别的适用性正在研究中。 [外文原描述]： IEC 60793-1-53:2014 provides a practical method for evaluating fibre performance in a defined environment. The purpose of this standard is to define a test that determines the suitability of sub-category A1a to A1d multimode fibres and class B and C single-mode fibres to withstand the environmental condition of immersion in distilled or demineralized water which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of immersion in water over a given period. This procedure is conducted in accordance with IEC 60068-2-18, Test R. This second edition cancels and replaces the first edition, published in 2001, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - harmonizing the content with sectional specifications of relevant fibre types; - extending the applicability of the standard to Class C single-mode fibres. Keywords: sub-category A1a to A1d multimode fibres, class B and C single-mode fibres, immersion in distilled or demineralized water
