IP Ingress Protection is a protection level standard developed by the International Electrotechnical Commission (IEC) to evaluate the protection of electrical equipment enclosures against solid particles (such as dust) and liquids (such as water).
1. Product range for IP dust and water resistance testing:
1，Consumer Electronics:Smartphones, smart watches, Bluetooth headphones, sports cameras;
2，Industrial equipment:PLC controllers, sensors, frequency converters, outdoor surveillance cameras;
3，Automotive Electronics:Car camera, car lights, charging interface, ADAS controller;
4，Outdoor lighting:Street lights, landscape lights, underwater lights, solar garden lights;
5，Household appliances:Sweeping robots, electric razors, kitchen appliances;
6，Medical equipment:Surgical instruments, monitors, portable ventilators;
7，Energy Equipment:Photovoltaic inverter, energy storage battery cabinet, charging pile.
2. Relevant standards for IP dust and water resistance testing:
1. IEC 60529 (International General Standard)
2. EN 60529 (EU standard)
3. ISO 20653 (for automotive electronics)
4. GB/T 4208-2017 (China standard, equivalent to IEC60529)
5. JIS C 0920 (Japanese Standard)
3. Test items for IP dust and water resistance test:
1, Dust test level (first digit):
1.1, IP1X ~ IP4X
1.2, IP5X
1.3, IP6X: Completely dustproof (no dust enters).
2, Waterproof test level (second digit)
2.1, IPX1 ~ IPX6
2.2, IPX7~ IPX8: Short-term/continuous immersion (such as 1 meter water depth for 30 minutes or more stringent conditions);
2.3, IPX9K: High-pressure and high-temperature water spray (suitable for industrial equipment).
4. IP dust and water resistance test method:
1. Dust test method:
1.1, Dust box test: Place the equipment in a closed dust box to simulate a sand and dust environment with a specific concentration and wind speed;
1.2 Vacuum test: Use negative pressure to detect whether dust penetrates into the equipment.
2. Waterproof test method
2.1, dripping test (IPX1/IPX2): Simulate a dripping scene vertically or tilted at 15°;
2.2, Spray test (IPX3/IPX4): Swing pipe or handheld sprinkler spray water from multiple angles;
2.3, high-pressure injection (IPX5/IPX6): 12.5L/min or 110L/min water injection;
2.4, Water immersion test (IPX7/IPX8): Soak in 1 meter water depth for 30 minutes or more.
Wu, IP dust and water resistance test process:
1. Determine test requirements: Select the target IP level based on product type and usage scenario;
2. Select a testing institution: a third-party laboratory with CNAS/CMA qualifications;
3. Sample delivery preparation: Provide 3-5 unpacked complete machines and technical data (such as design drawings and instructions);
4. Implement the test:
4.1, dust test (such as dust box, vacuum test);
4.2, waterproof test (select spraying, soaking and other methods according to grade);
5. Result determination: If there is no water or dust inside the equipment, it is passed;
6. Issue a report: The laboratory provides a certification report containing test parameters and conclusions.
