Scope:
Introduction
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.
It is not intended to show effects which are due only to the high or low temperature. For these effects, the dry heat test or the cold test should be used.
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.
Guidance on the choice of suitable test parameters for inclusion in the detail specification is given in Publication 68-2-33: Basic Environmental Testing Procedures, Part 2: Tests — Guidance on Change of Temperature Tests, which should be read in conjunction with this standard.
