The purpose of this standard is to evaluate the durability of airborne equipment and its components in an atmospheric environment of heat and humidity. Exposed to heat and humidity environments, airborne equipment may face problems such as metal corrosion, Non-metallic coating damage, moisture-absorbing material expansion, insulation material performance degradation, and even cause electrical problems and moving parts stuck. The standard requires test equipment to comply with the provisions of HB5830.1-84 to ensure the accuracy and conformity of the test environment. The test chamber structure needs to prevent condensation from dripping, maintain internal and external air pressure equilibrate, and be equipped with good test lead devices and grounding devices to ensure the test Reliability. This guide highlights the purpose of humidity cabinet testing, general effects, and requirements for test equipment, which helps to understand and apply to the environmental adaptability assessment of airborne equipment and equipment design improvement.
