MIL-STD-810 Humidity Testing Procedures
The 507.6 Humidity test method consists of two test procedures: Procedure I and Procedure II. To select the right test procedure, the customer takes into consideration the operational purpose of the equipment, the natural circumstances of exposure, the test data necessary to determine whether the operational purpose of the equipment has been achieved, and the duration of the test.
Procedure I – Natural (Open to the Environment) and Induced (Storage and Transit) Cycles
This test performs three cycles that represent natural and induced conditions. The Natural cycles consist of hot-humid, cyclic high humidity, and high humidity.
The induced cycles consist of induced constant high humidity and induced variable—induced hot-humid and high humidity.
Testing can take anywhere from 15 to 180 days based on the humidity cycle, system category, and whether conditions are induced or natural.
