Programmable sand and dust test chamber

Programmable sand and dust test chamberWorking principle:
By driving a certain concentration of sand and dust through the surface of the test samples at a certain flow rate with a fan, the ability of these test samples to resist the penetration effect of dust particles, the ability to resist the abrasion or blockage effect of gravel, and the ability to store and operate when exposed to dry sand or dusty atmosphere is tested.

sand dust test chamberThe test object
① The sealing performance of mobile phones, electrical products, and other products in dusty environments.
② The sealing performance of automotive and motorcycle components, seals, etc. during use, storage, and transportation in dusty environments.

sand dust test chamberDust proof test level
There are dust testing requirements for portable, outdoor, and automotive electronics, and corresponding testing requirements have been developed internationally by IEC, MIL, ETSI, and SAE.
IEC/EN60529 dust prevention is divided into 7 levels (level 0~level 6), dust prevention level (e.g. IP5X - dust prevention level 5)
Level 0: * No dust protection
Level 1: Can protect and prevent foreign objects with a diameter greater than 50mm from falling into the equipment
Level 2: Can protect and prevent foreign objects with a diameter greater than 12.5mm from falling into the equipment
Level 3: Can protect and prevent foreign objects with a diameter greater than 2.5mm from falling into the equipment
Level 4: Can protect and prevent foreign objects with a diameter greater than 1.00mm from falling into the equipment
Level 5: Cannot * prevent dust from entering, but the amount of dust entering must not affect the normal operation of the equipment and must not affect safety
Level 6: Dust prevention
