Anotation

IEC 61300-2-21:2009 determines the resistance of a fibre optic device 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. The changes with respect to the previous edition are: - to reconsider the whole parts of the standard; - to describe the apparatus and procedure in greater details; - to define with precision the number of 24 cycles in the severity. La CEI 61300-2-21:2009 determine la resistance des dispositifs a fibres optiques aux effets de deterioration dus aux conditions de temperature elevee, dhumidite et de froid. Elle est destinee a reveler les defauts dun dispositif en essai provoques par sa respiration, par opposition a la notion dabsorption dhumidite. Cet essai couvre leffet de la congelation de leau piegee dans des craquelures et des fissures aussi bien que celui de la condensation. Cependant, le niveau de condensation varie selon les dimensions et la masse thermique du dispositif en essai. Les changements par rapport a ledition precedente sont les suivants: - la reconsideration de toutes les parties de la norme; - la description de lappareillage et des procedures avec plus de details; - la definition avec precision du nombre de 24 cycles dans la severite.
