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 class A multimode fibres, class B and C single-mode fibres and class D polarization-maintaining fibres to withstand the environmental condition of change in temperature which can 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: Change of temperature with specified rate of change.
NOTE This test method may be used for other fibre categories if agreed between customer and supplier.
