The specific meaning of IP protection level

The meaning represented by the waterproof test level (IPX0-IPX9):

IPX0: indicates no protection;

IPX1: Waterproof vertical drip water, which should have no harmful effects. Use a drip tank for testing, with a testing time of 10 minutes;

IPX2: To prevent vertical dripping of water when the shell is tilted at 15 °, there should be no harmful effects. Use a drip tank with a water flow rate of 3mm/min and 2.5 minutes for each tilted position;

IPX3: The vertical surface of the shell should be drenched with water within a range of 60 °, and there should be no harmful effects. A pendulum tube drenching device should be used, and the testing time should be 10 minutes;

IPX4: To prevent splashing of water in all directions of the casing, there should be no harmful effects. Use a pendulum tube rain protection device to splash water within a range of ± 180 ° from the vertical direction, and the test time should be 10 minutes;

IPX5: To prevent water spraying in all directions of the casing, there should be no harmful effects. Use a 6.3mm diameter nozzle, 2.5 to 3 meters away from the sample, to spray water, and the testing time should be at least 3 minutes;

IPX6: Prevent strong water spraying in all directions of the shell, without harmful effects. Use a 12.5mm diameter nozzle, 2.5 to 3 meters away from the sample, for strong water spraying, with a testing time of at least 3 minutes;

IPX7: To prevent immersion in water at the specified pressure for a specified period of time, there should be no harmful effects (short-term immersion). Use a diving box, with the water surface at least 0.15m above the top of the shell and the bottom of the shell at least 1 meter below the water surface. The testing time should be 30 minutes;

IPX8: To prevent continuous flooding, there should be no harmful effects, and a diving box should be used. The waterproof depth and testing time should be determined through mutual consultation between the manufacturer and the user;

IPX9: Prevent spraying high-temperature and high-pressure water in each direction of the casing without harmful effects. Use a fan-shaped nozzle to spray small casings at different angles on a turntable (30 seconds in each direction), and spray large samples at a distance of 175mm ± 25mm, with a test duration of at least 3 minutes.

The meaning represented by the dust test level (IP0X-IP6X):

Protection against approaching hazardous components

IP0X: indicates no protection;

IP1X: To prevent the back of the hand from approaching dangerous parts, a 50mm diameter spherical test tool should maintain sufficient clearance with the dangerous parts;

IP2X: Prevent fingers from approaching dangerous parts. Articulated test fingers with a diameter of 12mm and a length of 80mm should maintain sufficient clearance with the dangerous parts;

IP3X: Prevent tools from approaching dangerous components, and test tools with a diameter of 2.5mm cannot enter the interior of the shell;

IP4X: Prevent metal wires from approaching dangerous components, and test tools with a diameter of 1.0mm cannot enter the interior of the shell;

IP5X: Prevent metal wires from approaching dangerous components, and test tools with a diameter of 1.0mm cannot enter the interior of the shell;

IP6X: Prevent metal wires from approaching dangerous components, and test tools with a diameter of 1.0mm cannot enter the interior of the shell;
