The main function of the dust ip test machine is to test the physical and other related properties of electronic and electrical products, lamps, electric cabinets, electrical components, automobiles, motorcycles and their parts and components under simulated dust climatic conditions.
Dust test standard (IP one characteristic number is 5-6)
1. The amount of talcum powder in the chamber is 2 kg. The talcum powder used will be sieved through a sieve, the nominal wire diameter of the sieve is 50 microns, and the nominal free distance between mesh wires is 75 microns. Talcum powder that has been used more than 20 times shall not be used for testing.
2. During the test, first hang the lamp outside the dust test chamber, and light it for 30 minutes under the rated power supply voltage.
3. Then put the working lamp on the shelf in the test chamber.
4. Close the door of the test chamber.
5. Select the working mode of the test chamber as the fixed value mode.
6. In the fixed value setting, select dust blowing in the running task with the serial number 01, and set the time to 1 minute.
7. After 1 minute, turn off the power of the lamp, and keep the test chamber in the "floating dust" state for 3 hours.
8. After 3 hours, open the door of the test chamber, brush off the talcum powder on the surface of the lamp shell and take it out. The enclosure is considered acceptable if no deposits of dust are evident in the enclosure.
Product Description
The LIB dust test chamber is suitable for testing the sealing performance of the product's shell, mainly used for the two levels of IP5X and IP6X tests specified in the shell protection standard. It is mainly to simulate the damage caused by sandstorm weather to locks, automobile and motorcycle parts, seals, power meters and other products.
Test standard
The sand and dust test chamber can meet the test requirements of the enclosure protection level of household appliances, low-voltage electrical appliances, automobiles, motorcycle parts and other parts in IEC60529.
Features
1. Studio: the inner tank is made of stainless steel plate, the sample rack and other accessories in the room are made of stainless steel, the design is reasonable and durable; the door is sealed with a silicone rubber sealing strip, which is tightly sealed and easy to open and close; the sealing strip has good resistance Aging and high temperature resistance properties.
2. Shell: stainless steel.
3. Observation window: There is a large-area glass observation window in the middle of the door of the test chamber, a dust scraper is installed in the window, and an observation lamp is installed in the chamber.
4. In order to gather the dust near the blowing hole when it falls, it adopts a conical bottom and is equipped with a periodic vibrator.
5. The unique air duct design ensures that the chamber produces non-layered vertical circulation airflow.
6. Design the dust inlet, the dust can be easily replaced at any time.
7. There are 4 movable casters on the bottom, which can move the equipment. There is at least 80mm of clearance at the bottom of the sand and dust test chamber, which can allow forklifts to pass through.
