Optical fibres - Measurement methods and test procedures. Dry heat (steady state) tests Ingestion-build-221493 PD IEC TR 62595‑1‑3 provides1 Scope 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 temperature (dry heat) which may occur in actual use, storage and or transport. The test is primarily intended to permit the
