IEC 61300-2-21 ED3

Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 2-21: Tests - Composite temperature/humidity cyclic test

Апстракт

IEC 61300-2-21:2026 defines the resistance of a fibre optic device or component to the deteriorative effects of high temperature, humidity and cold conditions.
It is intended to reveal defects in a device under test (DUT) caused by breathing as opposed to absorption of moisture. The test covers the effect of the freezing of trapped water in cracks and fissures as well as condensation. However, the degree of condensation will vary depending on the size and thermal mass of the DUT.
This IEC 61300-2-21:2026 includes the following significant technical changes with respect to the previous edition:
a) update of the terms and definitions and of the details to be specified and reported;
b) update of Figure 1 and Figure 2 according to IEC 60068-2-38: 2021.
