IEC 60068-2-14 provides tests with specified ambient temperature changes to analyse their impacts on specimens. The effect of change of temperature tests is determined by:
— values of high and low conditioning temperature between which the change is to be affected,
— the conditioning times for which the test specimen is kept at these temperatures,
— the rate of change between these temperatures,
— the number of cycles of conditioning,
— the amount of heat transfer into or from the specimen,
— the thermal conductivity and the materials of the specimen,
— the rate of change of the specimen’s temperature on its surface (respectively in relevant positions) or in its core.
