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 ā€œwith cable elements fixed at both endsā€; 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 Ā± 3 Ā°C as done in IEC 60794ā€‘1ā€‘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.
