The IP6X dust test chamber is an equipment used to test the dustproof performance of products. It is primarily used to simulate dusty environments to evaluate the dust resistance of test specimens. Below are the standard methods for the IP6X dustproof test:
1. Test Dust: Dry talcum powder is used as the test dust. The talcum powder must be sieved through a metal square-hole mesh with a wire diameter of 50 μm and a mesh size of 75 μm.
2. Dust Quantity: The amount of talcum powder used is 2 kg per cubic meter of the test chamber volume, and the number of uses should not exceed 20 times.
3. Test Duration: The duration of the IP6X test is 8 hours.
4. Internal Chamber Pressure: For the IP6X test, the product is considered the first type of enclosure, meaning that during the normal operating cycle of the device, the internal pressure is lower than the surrounding atmospheric pressure. During testing, a vacuum pump is used to maintain the chamber pressure, with an extraction volume of 80 times the volume of the test enclosure or vulnerable components. The extraction rate should not exceed 60 times the enclosure volume per hour, and under any circumstances, the pressure difference should not exceed 2 kPa (20 mbar).
5. Complete Dust Protection: IP6X indicates complete protection against dust entry. The equipment is designed to fully resist the intrusion of any form of dust, whether fine particles or larger dust, preventing them from entering the interior of the device.
6. Test Chamber Structure: The structure of the dust test chamber includes the chamber body, sandblasting device, circulation fan, filtration system, and sample rack. The chamber body is used to simulate the dusty environment, while the sandblasting device and circulation fan control the movement and circulation of dust particles. The filtration system effectively filters the dust particles.
7. Performance Indicators: These include the nominal spacing of the metal mesh, the nominal spacing between wires, the amount of talcum powder, the vibration time, the fan circulation time, etc.
This concludes the testing conditions and methods for the IP6X dust test chamber.
