适用范围：This part of IEC 61300 details a procedure for determining the suitability of a fibre opticdevice or closure to withstand variations in humidity and temperature that may occur duringoperation, storage and/or transport. The test is intended to indicate the performance of suchdevices when exposed to heat and humidity followed by short-term freezing.In general terms, this test provides a high temperature to induce potential failures due tosoftening and expansion, a high humidity to encourage moisture absorption and swelling anda low temperature to facilitate ice formation, embrittlement and contraction.This test differs from other cyclic environmental tests, notably the damp heat cyclic testof IEC 61300-2-46 and the composite temperature-humidity cyclic test of 61300-2-21, byincorporating alternative levels of severity. This is achieved througha) a greater number of cycles;b) a greater cyclic temperature range;c) a decreased cyclic period.
