Settling Dust tests are designed to measure the effectiveness of an enclosure at preventing dust ingress. Dust can act as an abrasive when it gets between moving parts.

Settling dust chambers test products by essentially showering a product with coats of dust within the chamber; this simulates the natural accumulation of dust from a product sitting in a typical location open to the atmosphere.

Dust protection of products are defined with an IP code rating established by IEC standard 60259. A product rated IP5X is dust protected, which means that dust ingress not fully prevented but is within tolerances of adequate product functionality; an IP6X rated product is fully protected from dust ingress.
