Detailed guide for dust test chamber

 



Dust test chamber is the name of "Sand Dust Test chamber", simulating the destructive effect of natural sand,dust and wind climate on products, suitable for testing the shell sealing performance of products, dust test chamber is mainly used for the ip5x and ip6x two grades of test in the standard of shell protection. The Sand Dust Test chamber has the dust vertical circulation air flow, the test uses the dust to circulate, the entire wind tunnel uses the import advanced stainless steel plate manufacture, the duct bottom and the conical hopper connection, fan inlet and outlet directly connected with the air duct, and then in the appropriate position to the top of the studio diffuser access to the studio body, the formation of "O" type closed vertical dust blowing system, so that airflow can flow smoothly, the maximum to disperse the dust evenly. A single high power low noise centrifugal fan is used to adjust wind speed according to the test.Dust test chamber


Working principle of dust test chamber

The Dust test chamber is driven by a fan. A certain concentration of dust is blown over the surface of the test specimen at a certain velocity.To test the ability of these test specimens to be exposed to the penetration of dust particles under the action of dry sand or dust-filled atmospheres,The ability to defend the abrasive or blocking effects of grit and the ability to store and operate.

Test object

① cell phone, electrical products and other products in the sand dust environment of the tightness.

② the sealing performance in the use, storage and transportation of the automobile, motorcycle parts, seals and so on in the sand dust environment.

 

Dust Test Grade

For portable, outdoor and automotive electronics have a dust test requirements, whether in the international IEC, MIL or ETSI and SAE have developed the corresponding test requirements.

iec/en60529 Dustproof is divided into 7 grades (Grade 0 ~ Grade 6), dustproof grade (E. G. ip5x-Dust Grade 5)

Level 0: No dust protection at all

Level 1: Protects against foreign bodies that have a diameter greater than 50 fall into the device

Level 2: Protects against foreign bodies that have a diameter greater than 12.5 fall into the device

Level 3: Protects against foreign bodies that have a diameter greater than 2.5 fall into the device

Level 4: Protects against foreign bodies that have a diameter greater than 1.00 fall into the device

Level 5: Can not completely prevent dust entry, but the amount of dust entered must not affect the normal operation of equipment, not to affect safety

Level 6: Completely dustproof
