Introduction of dust proof test equipment standards and test methods

Dust proof test equipment can also be called sand dust test box and dust resistance test instrument. It is used to test the dust level of products in a closed loop box by using talcum dust to simulate the free fall of dust.

What are the characteristics of the dust proof test equipment?
1. With the rapid development of modern industrial technology, the application fields of electrical and electronic products are increasingly broad, and the environmental conditions experienced by them are more and more complex and diverse. Only when the environmental conditions of the products are reasonably specified and the environmental protection measures of the products are correctly selected, can the products be protected from damage during storage and transportation and be safe and reliable during use.

2. Therefore, the artificial simulation environment test of electrical and electronic products is an essential part to ensure their high quality. The artificial simulated environmental test is a scientific summary of the actual environmental impact, which is characterized by typification, standardization, convenient use and comparison. The diversification of environmental conditions and the importance of environmental testing also put forward stricter requirements for environmental testing equipment.

The dust-proof test equipment is used to test the products for 1-6 different dust-proof levels, with 6 different categories, namely IP1X dust-proof test ball, IP2X dust-proof test finger, IP3X dust-proof test probe, IP4X dust-proof test line and ip56x sand dust test box.

The dust proof test equipment standard shall meet the technical parameter requirements of IEC60529:1989+A1:1999+A2:2013 Degrees of protection provided by enclosures (IP Code), GB4208-2017 Degrees of Protection by Enclosures (IP Code), etc.

Structural features of dustproof test chamber:
The shell of the facility is made of cold-rolled steel plate with electrostatic spraying, and the inner tank is made of high-grade stainless steel plate, with an overall beautiful appearance. A large area observation window and a manual wiper are set in the middle of the box door, so that the test condition of the test piece can be seen clearly during the test. The main controller of the facility uses an intelligent digital display controller. The main controller of the facility uses an intelligent digital display temperature controller. The humanized design of the operation method is easy to learn and use, and the operation of instruments of different action levels is mutually compatible. The input uses a digital correction system, with built-in common thermocouples and thermal resistance non-linear correction tables, and the measurement is stable. It has position adjustment and AI artificial intelligence adjustment functions, and has multiple alarm modes. The facility has a timing function. Stainless steel finned heating tubes are used for facility heating. The dust blowing cycle and vibration cycle of the whole facility can be adjusted, and the timer for the total test is equipped.

Test method of dust proof test equipment:
1. Clean the sample shell and try to avoid dust being brought into the test box.
2. Place the sample in the middle of the interior. If power on test is required, turn on the sample power.
3. Pour the screened talcum powder into the box. Note that the dust consumption is generally 2 kg/m3. Close the box door.
4. To start the equipment, it is necessary to set the test parameters, such as power on time, vibration time, dust blowing time, etc.
5. After the test, wait for the dust to stand for 30min, then open the box door and take out the sample for inspection. Be careful not to open the door of the box immediately to prevent dust from directly gushing out of the box and causing environmental pollution in the laboratory.

LISUN lauched 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.
