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 temperature (dry heat) which can occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of high temperature over a given period. This procedure is conducted in accordance with IEC 60068-2-2, Test Bd: Dry heat for heat-dissipating specimens with gradual change of temperature that are not powered during the conditioning period.
NOTE This test method may be used for other fibre categories if agreed between customer and supplier.
