How to Test MIL-STD-810F Method 501.4
MIL-STD-810 is a set of U.S. military standards for testing a piece of equipment's environmental design. Specifically, MIL-STD-810F method 501.4 is a standard for testing how equipment performs under high temperatures. The temperatures used will typically mimic those in storage or operational conditions. For the best results, testing should be done in a controlled environment, such as an enclosed chamber.

1
Determine the maximum temperature you're going to expose the equipment to. This temperature is typically based on the environmental conditions in the field. For example, if a military truck is going to be used during the summer months in Afghanistan, use the highest recorded summer temperatures in Afghanistan.
-
2
Test the temperature of the testing chamber with a thermometer and the piece of equipment with a thermocouple, and record these two temperatures. The testing chamber should be at approximately 75 degrees F.
-
-
3
Place the equipment in the testing chamber, and operate it to ensure it's working appropriately. Record the results. If it's malfunctioning, repair it before you test it with MIL-STD-810F method 501.4.
-
4
Close the testing chamber and begin increasing the temperature within the chamber. Do not increase the temperature more than 6 degrees F per minute.
-
5
Stop increasing the temperature when it reaches the temperature determined in Step 1.
-
6
Leave the piece of equipment in the testing chamber at the high temperature for seven days.
-
7
Decrease the temperature of the testing chamber to 75 degrees F after seven days.
-
8
Inspect and operate the equipment after it has cooled to the base temperature measured in Step 2. Record the results and compare them with the results from Step 3.
