Annotation

This Standard provides a test to determine the ability of components, equipment or other articles (hereafter referred to as "specimens") to withstand rapid changes of ambient temperature. The exposure times adequate to accomplish this will depend upon the nature of the specimen.

NOTE 1 Guidance on the choice of suitable test parameters for inclusion in the detail specification is given throughout this Standard.

This test is not intended to show effects which are due only to high or low temperatures. For these effects, the dry heat test or the cold test should be used.

A change of temperature test is intended to determine the effect on the specimen of a change of temperature or a succession of changes of temperature.

The effect of such tests is determined by

— values of high and low conditioning temperature between which the change is to be effected,

— 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.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
