DO-160 and MIL-STD-810 Environmental Testing for Aerospace Equipment
Turn installation conditions and mission profiles into defensible temperature, altitude, humidity, vibration and combined-environment tests.
What Are DO-160 and MIL-STD-810?
RTCA DO-160 defines environmental conditions and test procedures for airborne equipment. It supports qualification of avionics, sensors, displays, communication equipment, power supplies and other items installed on aircraft. The applicable test categories depend on the equipment location, aircraft type and certification basis—not every unit is subjected to every section.
MIL-STD-810 is a United States Department of Defense test-method standard for environmental engineering and laboratory testing. Its central principle is tailoring: the test program should represent the environments an item will encounter through storage, transport, deployment and operation. A contract or program specification determines which methods, procedures and severities apply.
DO-160 focuses on airborne equipment categories, while MIL-STD-810 emphasizes environment and mission-profile tailoring.DO-160 vs. MIL-STD-810: Which One Applies?

Pressure and Thermal Performance Must Be Evaluated Together
Cooling capacity falls as air density decreases, and a powered avionics unit may run hotter at altitude. Ask for chamber performance at the required pressure, temperature and specimen heat load—not separate best-case specifications.
Specify Feedthroughs Before Manufacture
List power, Ethernet, fiber, RF coax, pneumatic lines, thermocouples and cooling connections. Pressure-rated feedthrough design, cable length and connector access can determine whether functional testing is practical.
Demand Traceable Test Evidence
Confirm calibration, spatial mapping, pressure accuracy, data export, alarms, time synchronization and report requirements. Chamber controller data should align with functional and electrical measurements.
Failures Aerospace Testing Can Reveal
| Failure | Possible mechanism | Evidence to capture |
|---|---|---|
| Reset or communication dropout | Cold start, power margin, connector movement or timing drift | Bus log, supply trace, chamber profile and product temperatures |
| Overtemperature at altitude | Reduced convective cooling or internal hot spot | Multi-point thermocouples, power and pressure record |
| Seal or enclosure leakage | Pressure differential, thermal contraction or gasket damage | Leak test, inspection and pressure history |
| Display or sensor drift | Temperature sensitivity, pressure response or moisture | Reference measurement during and after exposure |
| Intermittent vibration fault | Connector fretting, cracked joint or fixture resonance | Vibration control data synchronized with functional events |
