About MIL-STD-810 Test Method 502

MIL-STD-810 Test Method 502 is a test standard designed to evaluate the effects of low temperature on material safety and integrity during storage, operation, and manipulation. Note that very few companies can perform this type of test since it is quite unique. It is mainly designed to test the operation of computer equipment at base temperatures. It is applicable to materials that should be deployed in low-temperature environments. Such a test can evaluate for instance:

  • Change of burning rates
  • Stiffening of shock mounts
  • Loss of lubrication and lubricants flow due to increased viscosity

Procedure For MIL-STD-810 Low Temperature Testing

Micom_MIL-STD-810_502.5 test methodThis test encompasses three different procedures:

  • Procedure I: evaluate effects of low temperatures during and after storage
  • Procedure II: how does the material operate under low-temperature conditions
  • Procedure III: manipulation by heavy, cold-weather clothed personnel

Procedures should be wisely chosen depending on multiple factors such as:

  • Purpose of the material
  • Natural exposure circumstances

Climatic conditions are then chosen based on the world areas in which the material will be used. If a material happens to be used worldwide, the choice must be made on the frequency of a given cold condition. A table is given below that lists temperature ranges with respect to the location:

How is MIL-STD-810 Temperature Testing Performed Based on Climate Conditions?

The specimen is put in the climatic chamber in its respective configuration (storage/operation/manipulation) at a temperature rate of 3°C/min. Temperature stabilization is then made depending on the chosen procedure. Complementary steps are then executed with respect to each procedure, followed by visual inspections.

Moreover, this test includes multiple temperature cycle ranges to imitate temperature conditions in different locations.

This method consists in placing samples in a chamber and operating temperature cycles for an amount of time discussed by both parties.
