纤维光学互连器件和无源元件基本试验和测量程序第2-46部分:试验湿热循环

[中文适用范围]： The purpose of this part of IEC 61300 is to describe a test to determine the suitability of a fibre optic device to withstand the environmental condition of high humidity and change of temperature which can occur in actual use, storage and/or transport. The test is primarily intended to determine the suitability of fibre optic components under conditions of high humidity - combined with cyclic temperature changes and, in general, producing condensation on the surface of the device under test (DuT). Absorption of moisture can result in swelling that would destroy functional utility, cause loss of physical strength, and cause changes in other important mechanical properties. Degradation of optical properties can also occur. Although not necessarily intended as a simulated tropical test, this test can, nevertheless, be useful in determining moisture absorption of insulating or covering materials. [外文原描述]： IEC 61300-2-46:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

Degradation of optical properties can also occur. Although not necessarily intended as a simulated tropical test, this test can, nevertheless, be useful in determining moisture absorption of insulating or covering materials. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) complete revision to harmonize with IEC 60068-2-30; b) addition of detail description Clause 4, General description; c) addition of detail description Clause 5, Apparatus; d) addition of detail description Clause 6, Procedure. Keywords: suitability of fibre optic devices to withstand the environmental condition The contents of the corrigendum 1 of February 2022 have been included in the English part of this of copy.
