Dust creates a harsh environment for chassis, underhood, and exterior mounted devices; and can be a long term problem in interior locations (such as under the dash and seats in automobiles). Exposure to fine dust causes problems with moving parts, forms conductive bridges and acts as an absorbent material for the collection of water vapor. Some electromechanical components may be able to tolerate fine dust, but larger particles affect or totally inhibit mechanical action.
Dust Test Specifications are designed to test a component's resistance to a dust-filled environment. The product is placed on the specimen rack and dust is agitated throughout the chamber by injecting compressed air into each of the dust troughs. The dust then settles, covering the product under test.
