Dustproof test box is suitable for testing electrical and electronic products, auto parts and seals in a sandy environment to prevent sand and dust from entering the seals and casings. The purpose of the performance test for examining the use, storage and transportation of electronic and electrical products, car and motorcycle parts and seals in a sandy and dusty environment is to determine the possible harmful effects of particles carried by the air flow on the product, to determine. The test can be used to simulate environmental conditions in free sandy air caused by natural environments or human disturbances such as vehicle movement.
Dustproof test level:
IEC/EN60529 dustproof level is divided into 7 levels (level 0~level 6), dustproof level (e.g. IP5X dustproof level 5)
1.Level 0: No dust protection
2nd level 1: It can prevent foreign objects with a diameter of more than 50mm from falling into the device
3.Level 2: It can prevent foreign objects with a diameter of more than 12.5m from falling into the device
4.Level 3: It can protect against foreign objects with a diameter of more than 2.5m falling into the device
5.Level4: It can protect against foreign objects with a diameter of more than 1.00m falling into the device
6. Level 5: It cannot prevent dust from entering, but the amount of dust entering must not affect the normal operation of the device, and must not affect safety
7.Level 6: Dustproof
