GB/T 2423.21-2008 "Environmental testing for electric and electronic products - Part 2: Test methods - Test M: Low air pressure" is specifically designed for low air pressure testing at room temperature. Its purpose is to evaluate the adaptability of products when stored, transported, or used in simulated low-pressure environments such as high-altitude or high-altitude conditions. The standard explicitly states that if a product is subjected to combined environments such as "high temperature + low air pressure" or "low temperature + low air pressure," the corresponding comprehensive test standards should be applied instead of this single test.
