Blowing Dust.........
.


Used to test product ability to resist the effects of a dry dust (fine sand) laden atmosphere. This test simulates the effect of sharp edged dust (fine sand) particles up to 150 microns in size which may penetrate into cracks, crevices, bearings and joints, and cause a variety of damage such as fouling moving parts, making relays inoperative, forming electrically conductive bridges with resulting "shorts" and acting as a nucleus for the collection of water vapor. This test is applicable to all mechanical, electrical, electronic and electrochemical and electromechanical devices exposed to the effects of a dry dust (fine sand) laden atmosphere.
