How can I do a dustproof test chamber? Many products have been used indoors and turned to outdoor use, which requires the product shell to withstand the harsh outdoor natural environment, which means that the product shell must be able to meet the protection level standard, which requires the product must be able to adapt to the
external environment.

It must be tested in the dustproof test box, talc powder should be filtered by metal square hole sieve, wire diameter 50um, sieve hole size of 75um, talc powder dosage of 2KG per cubic meter of test volume, the number of times used shall not exceed 20 times
.

Test Restricted Conditions: After the test, observe the location of talc powder deposit, as with other dust, is not enough to affect the normal operation or safety of the equipment, that is, the test is considered to be qualified
.
