IEC 60068-2-68 Sand And Dust Test Chamber For Automotive & Electronic IP Protection Testing


IEC 60068-2-68 Sand and Dust Test Chamber for Automotive & Electronic IP Protection Testing


Product information:


Conforms to IEC60068-2-68-La2, ISO20653-La2, IEC60529, etc.

This equipment is suitable for testing electrical and electronic products, automobile and motorcycle parts, and seals to prevent sand and dust from entering the seals and shells in a sand and dust environment. It is used to test the performance of electronic and electrical products, automobile and motorcycle parts, and seals in the use, storage, and transportation of sand and dust environments. The purpose of the test is to determine the possible harmful effects of particles carried by airflow on electrical products. The test can be used to simulate open sand and dust air environment conditions induced by natural environment or artificial disturbances such as vehicle movement.


Design Principle:


Design a conical funnel with a dust collection port at the bottom, and install a high-pressure turbine circulating fan suction port at the dust extraction port (bottom) to send the sucked dust to the top of the inner box and let it fall freely from top to bottom through the top of the box, thus starting a cycle over and over again.
