IEC 60529 IP56 Protection Against Foreign Object Dust Test Chamber

Complied Standards & Clauses

IEC60529:2013 “Degrees of protection provided by enclosure (IP code)” IP5 & IP6.

Equipment Overview

Structure: The machine adopts a closed chamber structure, a suspended man-machine interface operation device, a large visual window, the test circulates inside the cabinet. The inner chamber adopts a mirror panel and a special air duct design, which ensures to produce a standard concentration of laminar airflow in the chamber, there is a vacuum suction device is arranged.

The main structure includes outer chamber, inner chamber, dust suction port, dust recycling funnel, circulating dust blowing device, vacuum system, dust storage tank, flow valve, heating system, reverse flow blade, protective plug.

Samples and Restrictions: Electrical and electronic products, automobiles & motorcycle parts, seals, lamps

Application: To verify the performance of the use, storage and transportation of electronic and electrical products, automobiles & motorcycle parts, seals and lamps in a dusty environment, to determine the possible harmful effects to the product by the particles carried by the air stream.

Principle: There is a conical funnel with dust collection port at the bottom; the suction port of the high-pressure turbine circulation fan is installed at the dust extraction port (at the bottom), and the collected dust is sent to the top of the inner chamber and freely sprinkle from top to bottom.

It can simulate an open, dusty air environment condition induced by the natural environment or by human disturbances such as vehicle motion.

Use Environment: Power supply: AC380V±5%/50Hz,3KVA or match client’s local power supply requirements

Use place: temperature 15-35 ° C, relative humidity 25%-75%, atmospheric pressure 86~106kpa (860 mbar-1060 mbar); no sharp shaking, no vibration, no electromagnetic interference, no dust, no explosive & corrosive gas, with good heat dissipation.
