[中文适用范围]： This part of IEC 60793 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 change in temperature which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of change of temperature over a given period. This procedure is conducted in accordance with IEC 60068-2-14, Test Nb. La présente partie de l'IEC 60793 présente une méthode pratique pour l'évaluation des performances des fibres dans un environnement défini. L'objet de la présente norme est de définir un essai pour la détermination de l'aptitude des fibres optiques multimodales de sous-catégories A1a à A1d et des fibres optiques unimodales de classes B et C à résister aux conditions d'environnement présentant des variations de température, susceptibles de survenir en utilisation réelle, pendant le stockage et/ou le transport. L'essai est essentiellement destiné à permettre l'observation des effets des variations de température pendant une période donnée. Cette procédure est appliquée conformément à l'IEC 60068-2-14, Essai Nb. [外文原描述]： IEC 60793-1-52:2014 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 change in temperature which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of change of temperature over a given period. This procedure is conducted in accordance with IEC 60068-2-14, Test Nb. 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 document to class C single-mode fibres. Keywords: sub-category A1a to A1d multimode fibres, class B and C single-mode fibres, change in temperature
