This standard specifies the temperature-humidity-altitude test conditions and test methods for airborne equipment, which is used to determine the adaptability of the equipment to the extreme environments where low temperature air pressure and high temperature and high humidity may actually be encountered during use. This standard applies to non-airtight sealed equipment and other equipment with shell covers installed in non-temperature-controlled and non-pressurized cabins. Mainly due to the condensation produced by the alternating effects of low temperature, low pressure, high temperature and high humidity, which can cause serious consequences.
