Specifies tests to assess the resistance of equipment to high humidity conditions and the accompanying daily cycles of temperature such as those encountered in tropical areas.
1.1 This standard applies to equipment mounted externally on aircraft, to equipment in unpressurized bays protected from rain and sunlight by the aircraft structure, and to equipment in zones where no air-conditioning is applied while an aircraft remains out of service. It is not intended to be applied to equipment that is packed and in a store, but may be applied to such equipment that has been unpacked. The test determines the degree to which serviceability is impaired by corrosion or other deterioration.
