Do you know the waterproof level? We often hear that the selling point of a certain three-proof mobile phone is IP56 and IP68 waterproof. What is this "IP"? What does the number behind it mean? In fact, the IP here is the abbreviation of Ingress Protection, which means The degree of protection of the enclosure of an electronic device against the intrusion of foreign objects. The IP classification system was originally proposed by the International Electrotechnical Commission and defined in its IEC 60529 standard. The IP grading system is represented by IPXX, the first X represents the degree of protection of the enclosure against the intrusion of solid foreign objects (dust rating), and the second X represents the degree of waterproofing of the enclosure (waterproof rating). So what does each number mean: Dust rating Use the scale of 0-6 to distinguish its protection ability Waterproof grade Use 0-8 votes to distinguish its protection capabilities Can resist <50mm (diameter, the same below) solids, such as palms Can eliminate the harmful effects of vertically falling water droplets Protects against solids <12.5 mm, such as fingers Protects against water droplets falling within 15 degrees from vertical Protects against solids < 2.5 mm, such as screwdrivers Eliminates the harmful effects of spray-like water droplets at 60 degrees from vertical Protects against <1 mm solids such as wires Can eliminate the harmful effects of water droplets splashing from different directions Protects against dust sufficient to cause a hazard can eliminate harmful effects on water jets from nozzles in all directions Complete protection against dust intrusion can eliminate the harmful effects of strong water jets from nozzles in all directions The top is 0.15-1 meter away from the water surface for 30 minutes, the performance is not affected, and there is no water leakage The top is 1.5-30 meters away from the water surface for 30 consecutive minutes, the performance is not affected, and there is no water leakage The IP67 rating can achieve complete dust-proof effect, and it can be used for 30 minutes without leakage in the water depth below 1.5 meters. "IP68" is the highest level of

dustproof and waterproof level in GB/T 4208-2017 enclosure protection level (IP code). This level of protection already belongs to the professional-grade three-proof standard. But do you know how IP8 water resistance is tested? Haida has developed a water immersion test chamber, which fully meets the test requirements of GB/T 4208-2017 standard. It adopts digital and frequency conversion control technology to make the rainfall, the rotation angle of the test rack, the swing angle of the water spray pendulum and the swing of the pendulum tube. The frequency can be adjusted automatically. The...
