MIL-STD-810 Humidity Testing for Custom Power Supplies<\/h1>\n<\/div>

At Viable Power, we perform in-house MIL-STD-810 Humidity Testing (method 507.6) on our power supplies based on our clients\u2019 needs and requirements. These tests ensure the dependability and durability of our ruggedized power supplies when operating in humid environments.<\/p>\n

When performing our tests under MIL-STD-810, we check for the ability of the power supply to withstand the changes and effects of condensation and water while continuing to function correctly. After each humidity test, we perform a full acceptance test to verify the effect of humidity on the components and circuit boards.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

MIL-STD-810 Humidity Testing Procedures<\/h2>\n<\/div>

The 507.6 Humidity test method consists of two test procedures: Procedure I<\/strong> and Procedure II.<\/strong> 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.<\/p>\n<\/div>

Procedure I – Natural (Open to the Environment) and Induced (Storage and Transit) Cycles<\/h4>\n<\/div>

This test performs three cycles that represent natural and induced conditions. The Natural cycles consist of hot-humid, cyclic high humidity, and high humidity.<\/p>\n

The induced cycles consist of induced constant high humidity and induced variable\u2014induced hot-humid and high humidity.<\/p>\n

Testing can take anywhere from 15 to 180 days based on the humidity cycle, system category, and whether conditions are induced or natural.<\/p>\n<\/div><\/div><\/div>

Procedure II – Aggravated<\/h4>\n<\/div>

This test exposes the custom power supply<\/a> to more extreme humidity levels and temperatures than found naturally in the outside environment.
\nResults are quickly obtained using this test method\u2014however, the observed effects may not accurately represent real-world conditions.<\/p>\n

There are a minimum of ten mandatory 24-hour cycles for this test. However, the tester can increase cycle levels to increase confidence in the power supply and its ability to survive in high-humidity and high-temperature environments.<\/p>\n<\/div>
