This standard BS EN 60793-1-50:2015 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 determine the suitability of optical fibre sub-category A1a to A1d multimode fibres and class B and C single-mode fibres to withstand the environmental condition of high humidity and high temperature which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of high humidity at constant temperature over a given period. This procedure is conducted in accordance with IEC 60068‑2‑78, Test Cab.
NOTE
The applicability of this test to other fibre categories is under study.
