Annotation of standard text IEC 60794-1-212-ed.1.0 :
IEC 60794-1-212:2024 defines the test procedure to examine the attenuation behaviour (change in attenuation) when an optical fibre cable with cable elements fixed at both ends is subjected to temperature cycling. This test assesses the attenuation behaviour of a cable under a no-end movement condition intended for termination with, for example, interconnecting devices or passive components. This document partially cancels and replaces IEC 60794-1-22:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60794-1-22:2017: a) the description of the test method has been changed to “with cable elements fixed at both ends”; b) subclauses have been added to the procedure clause; c) the preparation of cable sample and test set-up has been arranged in a logical way; d) Figure 1 has been added for illustration of the preparation of cable sample, DUT and test set-up; e) the temperature chamber temperature tolerance has been changed to ± 3 °C as done in IEC 60794-1-22, method F1; f) all required steps have been added to the subclause for temperature cycling as well as the table for the minimum soak time and the figure for the cycle procedure, and removed the reference to IEC 60794-1-22, method F1; g) the maximum change in attenuation has been added to the details to be specified; h) a new subclause 4.5 has been added for details to be reported. IEC 60794-1-212:2024 definit la procedure d’essai pour examiner le comportement en affaiblissement (variation de l’affaiblissement) d’un cable a fibres optiques avec elements de cable fixes aux deux extremites soumis a un cycle de temperature. Cet essai evalue le comportement en affaiblissement d’un cable dont les extremites ont ete bloquees et destine a etre raccorde a des dispositifs d’interconnexion ou des composants passifs, par exemple. Ce document remplace partiellement l’IEC 60794-1-22:2017. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’IEC 60794-1-22:2017: a) modification de la description de la methode d’essai comme suit: “avec des elements de cable fixes aux deux extremites”; b) ajout de paragraphes a l’article relatif a la procedure; c) adaptation de la preparation de l’echantillon de cable et du montage d’essai de maniere logique; d) ajout de la Figure 1 pour representer la preparation de l’echantillon de cable, du DUT et du montage d’essai; e) modification de la tolerance de temperature de l’enceinte thermostatique a ± 3 °C, comme cela est indique dans l’IEC 60794-1-22, methode F1; f) ajout de toutes les etapes exigees dans le paragraphe relatif au cycle de temperature, ainsi que le tableau pour determiner la duree d’exposition minimale et la figure relative a la procedure de cycle, et suppression de la reference a l’IEC 60794-1-22, methode F1; g) ajout de la variation maximale de l’affaiblissement dans les informations detaillees a specifier; h) ajout d’un nouveau paragraphe 4.5 pour les informations detaillees a consigner.
