MIL-STD-810G Method 504.2 Fluid Contamination Test

The purpose of this test is to evaluate the effects of temporary exposure to liquid contamination on the performance or use of the material.

Temporary contamination of liquids with ammunition, etc. The effects on it are as follows.

• Packaging Defects.
• Cracks and expansion in plastic or rubber
• Defects in gaskets or gaskets
• poor adhesion
• Peeling of paint etc.
• Wear
• melting or corrosion

This test should be done after the environmental test and the test procedure is one.

Test result decision

The results of the tests should be analyzed and judged for their immediate or potentially long-term effects on the proper functioning of the material. Therefore, when evaluating the results of this test, only the results immediately after the test should not be used as an evaluation criterion.

Test request conditions

The following are the minimum ingredients that must be specified when requesting a test.

• Type of fluid (including gasoline, kerosene and additives. Liquid compressed fluid, lubricating oil, solvent cleaner - de-icing and antifreeze, especially de-icing fluid, pesticide, disinfectant, coolant dielectric fluid, extinguishing agent, etc.), whichever is suitable or If more fluid is to be administered, individual or sequential effects, sequence of exposure, and inter- or post-test cleaning should be considered.
• exposure time, soaking time
• Exposure temperature and test item temperature, liquid temperature, suction temperature
