BS EN 60793-1-50:2015

Optical fibres. Measurement methods. Damp heat (steady state) tests

Status : Current   Published : January 2015



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.


The applicability of this test to other fibre categories is under study.
