JIS C 0031:1995

This Japanese Industrial Standard deals with combined dry heat (with rapid or gradual change of temperature (see 8.2.2 and 8.2.8)) and low air pressure tests for both heat-dissipating and non-heat-dissipating specimens. The object of the test is to determine the ability of components or equipments or other articles to be stored and used under a simultaneous combination of high temperature and low air pressure. This combined test should normally be used only if the effects of combined environments will not be revealed by subjecting the specimen to single environments. The procedures given in this Standard are limited to the case of specimens which achieve temperature stability during the test procedure. In the case of testing heat-dissipating specimens, this procedure applies only to the testing of one specimen at a time.
