Dust Test Chamber is designed to simulate dust in controlled atmosphere. It aims to determine the degree of protection against harmful deposits of dust (IP5X) and against ingress of dust (IP6X).  Numeral 5 allows a limited quantity of dust to penetrate the enclosure under certain conditions.  Numeral 6 does not allow any dust to penetrate. 

There are mainly two kinds of test - (F) suspension dust & (C) flow dust, to test dust-resistance for safety of operation
