Dust proof test is used to detect the test of electrical and electronic products, automobile and motorcycle parts and seals to prevent sand dust from entering the seals and shell in the sand dust environment, and to determine the impact of suspended sand dust in the air on the products. To test the use, storage and transportation performance of electronic and electrical products, automobile and motorcycle parts and seals in sand and dust environment.
Dust proof grade
IEC / en60529 dust prevention is divided into 7 grades (grade 0 ~ grade 6), and dust prevention grade (e.g. ip5x - dust prevention grade 5)
Level 0: no dust protection at all
Level 1: it can protect and prevent foreign matters with a diameter greater than 50mm from falling into the equipment
Level 2: it can protect and prevent foreign matters with a diameter greater than 12.5mm from falling into the equipment
Level 3: it can protect and prevent foreign matters with a diameter greater than 2.5mm from falling into the equipment
Level 4: it can protect and prevent foreign matters with a diameter greater than 1.00mm from falling into the equipment
Level 5: dust cannot be completely prevented from entering, but the amount of dust entering shall not affect the normal operation of the equipment and safety
Level 6: completely dustproof
