Yusong frost test chamber meets the freezing rain test requirements of MIL STD 810FIn the test method "521.2 Icing/Freezing Rain" of the MIL STD 810F standard, the relevant requirements for the ice accumulation and freezing rain test are provided. Let's take a look at the relevant requirements for this test.
Test equipment: HUANYI instrument, Yusong frost test box
Test purpose: The icing test is designed to evaluate the impact of icing on material combat capabilities. This method also provides testing to evaluate the effectiveness of de-icing equipment and techniques, including prescribed methods that can be used in the field.
Experiment procedure:
step 1.
Stabilize the test item temperature at 0℃ (-0/+2℃).
Step 2.
Provide a uniform spray of pre-cooled water for 1 hour to allow water to penetrate into the gaps/openings in the test item (a water temperature of 5°C and a water supply rate of 25 mm/hour is appropriate).
Step 3.
Adjust the indoor air temperature to -10°C or as specified and maintain the water spray rate until the required thickness of ice has accumulated on the appropriate surface. Wind or side spray may be used to aid ice accumulation on the sides of the test item.
Step 4.
Maintain room air temperature for at least 4 hours to allow the ice to harden. Check for safety hazards and attempt operational test items where appropriate. Record the results (take photos if necessary).
Step 5.
If step 4 fails or specifications allow for de-icing, remove the ice.
Step 6.
Check for safety hazards and, if appropriate (and possible), attempt to operate at the low operating temperatures specified for the test item materials in place.
Step 7.
If necessary, repeat steps 3 through 6 to produce other desired thicknesses of ice.
Step 8.
Stabilize test items under standard environmental conditions and perform post-test operational checks.
If you have any questions about the above-mentioned MIL STD 810F icing test, you can consult the relevant technical personnel of "Environment Instrument".
