This standard specifies the severity level, pretreatment, initial measurement, condition test, recovery and final measurement of the low air pressure test method for electrical and electronic products. This standard applies to low pressure tests at room temperature. It is mainly used to determine the suitability of components, equipment or other products for storage, transportation or use under low pressure conditions. Note: For products under storage, transportation or use conditions, when high temperature and low pressure or low temperature and low pressure combine to affect the stress on the product or the failure mechanism under this stress is very important, the following standards should be followed Test: GB2423.25 and GB2423.26.
