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 class A 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: Damp heat, steady state.
NOTE This test method may be used for other fibre categories if agreed between customer and supplier.
