This Japanese Industrial Standard specifies testing procedures to determine the effect of a changes of temperature or a succession of change of temperature on components, apparatus or other products, hereinafter referred to as "specimens". The effect of a change of temperature or a succession of changes of temperature is determined by the following matters: (1) The low and high conditioning temperatures (2) The conditioning times for which the specimen is kept at these low and high temperatures (3) The rate of change between these low and high temperatures (4) The number of cycles of conditioning (5) The amount of heat transfer into or from the specimen This test is not intended to confirm the effects only due to exposure of specimen to the low or high temperature. Therefore, for checking these effects, application of the cold test of JIS C 0020 or the dry heat test of JIS C 0021 is recommended.
