The first digit of service details: Dust test 1, IP1X: represents that a spherical test tool with a diameter of 50mm cannot enter the gap and enter the interior of the product; 2. IP2X: represents that a spherical object with a diameter of 12.5mm cannot penetrate the product gap; 3. IP3X: Refers to an object with a diameter of 2.5mm that cannot pass through the product gap; 4. IP4X: Metal wires with a diameter of 1mm cannot pass through product gaps and affect hazardous components; 5. IP5X: Place it in a sand and dust box, open the cover and check if there is no dust entering the interior of the product. If there is any dust that does not affect the product performance, it can also determine the load standard requirements; 6. IP6X: The product needs to be vacuumed and placed in a sand and dust box. After opening the cover for inspection, it is classified as dust tight and no dust can enter. It is judged to meet the standard requirements; The second digit: waterproof test 1. IPX1: represents vertical dripping, with no effect on vertical dripping. The water flow rate is 1mm/min, and the test lasts for 10 minutes; 2. IPX2: 15 degree drip, when the vertical surfaces of the shell are tilted within 15 degrees, the vertical drip should have no harmful effects, and the water flow rate is 3mm/min, with each tilted position for 2.5 minutes; 3. IPX3: Water spraying test, with each vertical surface raining within 60 degrees without harmful effects, with a water flow rate of 10L/min and a test time of 10min; 4. IPX4: splashing water, splashing water in all directions of the shell has no effect, and each vertical plane is exposed to rain within the range of 152 0173 3840 degrees. The water flow rate is 10L/min, and the test time is 10min; 5. IPX5: Spray water in all directions of the shell without any impact, with a water flow rate of 12.5L/min and a test time of 3min; 6. IPX6: Strong water spraying, with no harmful effects in all directions of the shell. The water flow rate is 100L/min, and the test time is 3 minutes; 7. IPX7: Immerse in water for a short period of time. After immersion in water at the specified pressure for a specified period of time, the water immersion of the shell will not reach a harmful level. Place it in a submerged water tank, usually at a depth of 1 meter, and the test time is 30 minutes; 8. IPX8: Continuous immersion, with the manufacturer and user negotiating the depth and time of immersion.
