Abstract

Exotic Electro-Optics (EEO) recently completed a series of MIL-STD-810F, Method 510.4 sand erosion tests at multiple commercial testing sites. During this testing process, it became apparent that no two environmental test vendors are alike, even if MIL-STD-810F is specified in all cases. Three different test laboratories performing the same Method 510.4 sand test on identically fabricated samples yielded three different results. Ultimately, it is the responsibility of the Engineer to confirm that the test vendor’s equipment, processes, and procedures produce a test environment that is applicable and a result that is accurate based upon the customer specified test requirement and the MIL-STD-810 methodology. Some critical factors that determine the utility of a test are particle concentration, air velocity, particle size and composition, and the ability to maintain these parameters over test duration of up to 90 minutes. EEO has identified a number of parametric details critical to maximizing the stability and accuracy of MIL-STD-810F, Method 510.4, Procedure II sand testing. These strategies will be presented.
