IEC 60793-1-53:2014提供了一种在规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和C类单模光纤在实际使用、储存和/或运输中可能出现的浸泡在蒸馏水或软化水中的环境条件下的适用性。该试验主要是为了观察在给定时间内浸入水中的效果。该程序按照IEC 60068-2-18试验R进行。第二版取消并取代了2001年出版的第一版，构成了技术修订。与上一版相比，此版本包括以下重大技术变更:-使含量与相关纤维类型的截面规格相协调； -将标准的适用性扩展到C类单模光纤。 关键词:亚类A1a至A1d多模光纤，B类和C类单模光纤，浸没在蒸馏水或软化水中

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
