MIL-STD-810 HISTORY AND FORMATION
– MIL-STD (Military Standard) stands for Military Standard.
– MIL STD 810 is a set of various tests designed by the US military to test equipment specifications in use (environment) or in storage (shocks).
– The test apparatus varies according to the specifications, size, and weight of the equipment being tested.
– The MIL-STD-810 test method standard is a distribution provided by the US Department of Defense with contributions from the US Army, Air Force, and Navy, as well as the Institute of Environmental Sciences and Technology (IEST).
– The initial version of MIL-STD-810 was released in 1962.
– Revisions were made alphabetically, and MIL-STD-810G, revised in 2008, is still widely used.
– MIL-STD-810H was published in January 2019.
– In 2022, MIL-STD-810G (with CHANGE-1) was published.
MIL-STD-810 PURPOSE AND SCOPE
The MIL-STD 810 Standard consists of 29 laboratory test methods used to test the ruggedness of materials.
A portion of the 1,089-page MIL-STD-810H document defines the purpose of MIL-STD-810 as “systemically considering potential harmful entities over the service life of a specific material system in various markets.”
In simpler terms, the purpose of MIL-STD-810 is:
Identification of environmental life series, equipment, and equipment operating life.
Analyzing and developing the test by adapting the test sample to the working environment in the field.
Demonstrating compliance of the test sample with the required conditions and evaluation under the required life cycles.
Identifying deficiencies and defects in test sample design, production parts, packaging techniques, and maintenance programs.
