Dustproof test chamber is designed according to IEC60529 for IP5X&IP6X tests and IEC60068-2-68 method La2 (constant air pressure), the object of this test is to determine the degree of protection against ingress of fine dust into electrotechnical products, like outdoor luminaire, household appliance, auto parts and other similar electrical products.
This is a dust tightness test in which the specimen is exposed to a heavily dust-laden air flow containing non-abrasive powder of particle size <75μm, and checking the the physical and other relevant properties of the product to provide the basis for product design, improvement and verification. The test does not simulate natural or induced environments, a vertical downwards air flow is specified for the test. Enclosures of a specified category are tested with the internal air pressure lower than the surrounding atmospheric air pressure in order to encourage the ingress of powder, the specified quantity of powder ensures that the dust concentration is extremely high and uniform. Thus, this test chamber is equipped with a dust blower device for exciting and blowing the dust into the sealed test chamber. According to the agreement and relevant regulations, the vacuum device is an optional device for IP5X test, and for IP6X and La2 testing, the test sample should be connected to a vacuum pump to pump the air inside, so that the air flow in the dust chamber can enter the sample through gaps, bushings or other similar parts; the pressure pipeline is provided with a regulating valve, a monitoring vacuum pressure gauge and a gas flow meter to measures the pumping rate. The dust falls settled at the bottom of the test box is recycled. In order to prevent the dust from adhering to the inner wall of the chamber and reduce the dust concentration, the bottom of the box is set in a funnel shape and equipped with a dust shaking device, which is convenient for dust recovery, the dust shaking cycle and the time is controlled by the central controller.
