   ① Dust blowing time (stop, blowing) h/m/s adjustable

   ② Cycle period: arbitrarily adjustable

   ③ Preset test time: 0s～999h99m99s, arbitrarily adjustable

   ④ Power supply: off-on-off

o. Metal screen size: nominal wire diameter 50um, nominal distance between wires 75um or less than 150um

p. Fan: All plastic centrifugal fan

Remarks: This test chamber can meet the requirements of degrees of protection provided by enclosures of household appliances, low-voltage electrical appliances, automobile, motorcycle parts and etc.

Structure and Panel Description:

The structure and working principle of the dust test chamber are the same as IEC60529-2013, and equipped with an additional airflow heating device, in order to facilitate the use in the case of low ambient temperature or high humidity. When the system is working, operator first puts the dried standard talc powder (2kg/M3) into the dust test chamber, then puts test sample into the dust test chamber, and then starts the fan to make a high-density dust mist formed in the chamber until the preset test time is reached (Usually 8h).
