Principle explanation and precautions of dustproof test chamber

The scientific name of dustproof test chamber is sand and dust test chamber, which is widely used, including but not limited to the protection level test of various products such as electronic and electrical products, LED lighting fixtures, diving field, automobiles and automobile accessories. The dustproof test chamber is a device used to test the influence and reliability of external environment on electronic components and instruments.

There are six types of dust test: IP1X dust test ball, IP2X dust test finger, IP3X dust test probe, IP4X dust test line and ip56x sand and dust test chamber. It uses talcum powder to test the dust level of the shell of the product under the test environment with no wind speed from top to bottom in the dust test chamber.

Use and operation tutorial of dustproof test chamber:
Machine operation steps：
1. Pour talcum powder evenly into the bottom of the chamber.
2. Place the test sample (lamp) in the center of the network and connect it to the dust-proof socket (note: pay attention to the safety of electricity before the sample is powered on);
3. Close the door and press the “Test Start” button to automatically start the dust test. The test stops automatically until the set time.

Pretreatment sample：
1. If the technical conditions of the sample are required, the sample shall be pretreated as required to keep the sample dry. The dustproof test is a part of the shell protection test and is usually connected with the waterproof test. After the waterproof test, the sample must be dried before being put into the dustproof chamber. If no pretreatment conditions are specified for the sample, the sample shall be placed for more than 2 hours according to GB2423.37.
A. Temperature: between 15 ℃ and 35 ℃;
B. Relative humidity: 45% – 75%;
C. Atmospheric pressure: 8kpa-106kpa

Precautions for dustproof test chamber:
1. Please pay attention to placing the device in a dry environment with good ventilation conditions.
2. Check the general functions before use (you can directly enter the manual screen)
3. Remember to turn off the power after use.
4. It is recommended that talcum powder be used no more than 20 times, and can be recycled and cleaned through the bottom of the device.
5. Regularly clean the inside of the chamber to avoid internal dust scaling, which may cause air outlet blockage.
6. Level the ground as much as possible to make the equipment run more stably.

What should I know about the purchase of dustproof test chamber?
1 Select the model according to the actual demand according to the product size, material, working environment and other factors. The selection of appropriate sand and dust test chamber model can meet the requirements of product testing and ensure the accuracy and reliability of the test results.

2 Performance parameters of sand and dust test chamber procurement. Considering the accuracy of the equipment, the scope of the vacuum meter, the pumping speed, the simulation speed and other aspects, selecting and purchasing the sand and dust test chamber with stable performance, accurate data and easy operation can improve the working efficiency.

3. Quality and after-sales service of dust test chamber procurement. Choosing a brand of dustproof test chamber with quality assurance and perfect after-sales service is conducive to reducing the maintenance frequency, and at the same time, it can also get professional maintenance support in time to improve the service life of the equipment.

4 Maintenance is also considered. In the process of use, reasonable maintenance can extend the service life and reduce the failure rate. Therefore, when selecting equipment, it is necessary to understand the maintenance conditions and precautions of the equipment, and arrange professional personnel for regular maintenance and cleaning.

SC-015 Dust-proof Test Chamber (Sand Dust Chamber) is applied to physical and other related performance tests for electronic and electrical products, lamps, electrical cabinets, electrical components, automobiles, motorcycles and their parts and other products under simulated dust climate conditions. After the measurement, it is judged whether the performance of the product meets the requirements through verification, so as to facilitate the design, improvement, verification and factory inspection of the product. Comply meets IEC60529:1989 +A1:1999 +A2: 2013 <Degrees of protection provided by enclosures (IP Code)>,IEC60598-1,  GB2423.37-89 (Test L: dust test methods), GB4208, GB/T 4942.2-93(protective casing grade of low-voltage apparatus), GB7000.1 <Luminaires Part 1: General Requirements and Tests> 9.2.1, 9.2.2 and Figure 6, DIN40050 and IP5K0. The dust test chamber is applicable to the IP5X and IP6X dustproof test of the products.
