Fluid Susceptibility Testing Services RTCA DO-160 Section 11, Mil-Std 810 Method 504.1 Contamination by Fluids

RMTS offers fluid susceptibility testing services which evaluate how much damage is done to a product by exposure to liquids and how product design can help prevent failures by fluid contamination. With the high probability that fluids will contaminate their product during its life cycle, we assist product manufacturers who often have their materials undergo fluid susceptibility testing. Fluids used to test contamination would include fuels, lubricating oils, solvents, cleaning fluids, and many other fluids.

The fluid classes mentioned below commonly contaminate material either intermittently or over long periods of exposure. Physical, chemical, and electrical properties are inspected during and after testing. For example, the product should not show any cracking or swelling when exposed to fluids.

Our fluid contamination testing program is kept up-to-date with the latest standards from the automotive, industrial, aerospace, and defense industries including MIL-STD-810 E/F/G (Method 504), RTCA DO-160 E/F/G (Section 11 - Fluid Susceptibility). We maintain a current list of specific fluids used for aircraft engine parts and components.
