This standard BS EN 60793-1-52:2014 Optical fibres is classified in these ICS categories:
33.180.10 Fibres and cables
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.
NOTE The applicability of this test to other fibre categories is under study.
