Applied Technical Services provides Sand and Dust Testing capabilities through our environmental testing laboratory. Sand and Dust Testing is a means of evaluating the long-term survivability of materials and devices in dusty and sandy environments such as plains and deserts. The testing procedures examine potential mechanical, electrical, and thermal issues due to dust and sand penetrating crevices and cracks, obstructing openings, and disrupting joints and bearings. Military standard 810 defines dust particles to be less than 150 micrometers in diameter and sand particles as 150-850 micrometers in diameter.
