Product catalog summary

Introduction to IP Ratings:
The document explains the IP (Ingress Protection) rating system, which indicates the level of protection an electronic device's enclosure provides against foreign objects and water. The IP rating is defined by the International Electrotechnical Commission's IEC 60529 standard and is represented as IPXX, where the first 'X' denotes protection against solid objects (dust rating) and the second 'X' denotes waterproofing.

Dust Rating:

Level 0: No protection.
Level 1: Protects against solids >50mm, like palms.
Level 2: Protects against solids >12.5mm, like fingers.
Level 3: Protects against solids >2.5mm, like screwdrivers.
Level 4: Protects against solids >1mm, like wires.
Level 5: Protects against dust that could cause harm.
Level 6: Complete protection against dust.

Waterproof Rating:

Level 0: No protection.
Level 1: Protects against vertically falling water droplets.
Level 2: Protects against water droplets falling within 15 degrees from vertical.
Level 3: Protects against spray-like water droplets at 60 degrees from vertical.
Level 4: Protects against water splashes from different directions.
Level 5: Protects against water jets from nozzles in all directions.
Level 6: Protects against strong water jets from nozzles in all directions.
Level 7: Protects against immersion in water up to 1 meter for 30 minutes.
Level 8: Protects against immersion in water up to 30 meters for 30 minutes.

IP67 and IP68 Ratings:
IP67 provides complete dust protection and allows immersion in water up to 1.5 meters for 30 minutes without leakage. IP68 is the highest level of dustproof and waterproof protection, suitable for professional-grade applications.

Testing for IP8 Water Resistance:
The document describes a water immersion test chamber developed by Haida, which meets the GB/T 4208-2017 standard. The chamber uses digital and frequency conversion control technology to simulate various water exposure conditions. It features a stainless steel construction, pressure protection, and a touch screen for operation, ensuring accurate and reliable testing.

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 shell...
