MIL-STD-202H serves as the definitive Department of Defense benchmark for testing the durability of electronic and electrical component parts. Unlike system-level standards, this protocol rigorously evaluates how individual components—such as capacitors and relays—withstand harsh natural elements and military-grade physical stress. By validating against these test methods, manufacturers demonstrate that their components can survive the extreme realities of defense and aerospace operations.

Standard: MIL-STD-202H : 2015 (Department of Defense Test Method Standard: Electronic and Electrical Component Parts). Status: Active / Current. Revision Note: This version (Revision H) was issued on April 18, 2015, and supersedes the previous Revision G. It is the governing document for all new component qualification programs requiring military-grade verification.
This standard is specifically designed for component parts weighing up to 300 pounds. It does not apply to complex systems (like entire servers or vehicles), but rather the fundamental building blocks of electronics:
Our testing scope covers the critical "100-Series" Environmental Tests defined within MIL-STD-202H, simulating the most destructive natural forces a component will face:
To ensure your test report is accepted by Defense contractors and Global OEMs, testing is conducted strictly under ISO/IEC 17025 accredited quality management systems.
Timelines for MIL-STD-202H vary significantly based on the specific "Method" chosen, as some tests are time-fixed by the standard itself.
The number of samples depends on whether the selected test method is Destructive or Non-Destructive.
Costs are calculated based on the "Test Method" and the duration of chamber occupancy.
To initiate the testing process and ensure the correct parameters are applied, the following documents are required:
They differ primarily in scope. MIL-STD-202 specifically tests small individual components like capacitors and relays, whereas MIL-STD-810 is designed for evaluating complete equipment systems and larger enclosures.
It depends on the method. Non-destructive tests can run sequentially on one sample, but destructive tests like salt spray typically require fresh samples to strictly isolate specific failure modes.
While not mandatory for civilian goods, high-reliability sectors like aerospace and heavy industry often require it. It serves as a rigorous benchmark to prove superior component durability and robustness.
Failure is defined by physical damage, such as cracking or excessive corrosion, or significant deviation in electrical parameters like resistance and voltage breakdown after exposure to environmental stress.
Test Conditions define the severity level, such as specific temperature extremes or duration. You must select the condition that best matches the intended operating environment of your specific component.
