Test conditions: drip volume 1.0+0.5mm/min Test duration: 10min
(2) IPX2
Method name: tilting 15° drip test test equipment: drip test apparatus and test method
Place the sample: make a 15° angle from the vertical line of the sample, and the distance from the top of the sample to the drip outlet should not exceed 20mm. After each test, change the other side for a total of four times.
Test conditions: drip volume 3.0+0.5mm/min Test duration: 4*2.5min 10min
(3) IPX3
Method name: Rain test a. Pendulum tube test
Test equipment: pendulum tube type water splash test
Place the sample: Select the appropriate radius of the oscillating tube, so that the height of the sample table is on the diameter of the oscillating tube. Place the sample on the sample table so that the distance from the top of the sample to the sample water outlet is less than 200mm. The sample table does not rotate. Test conditions: The number of water jets near the pendulum tube is also calculated, each 0.07L/min. When water is poured, the water spray hole in the 60° arc section on both sides of the midpoint of the pipe is sprayed to the sample. The sample was placed in the center of a semi-circular tube. Swing the pipe along each side of the vertical 60 °, a total of 120 °. Each swing (2x120°) is about 4s. Test pressure: 400kPa
Test time: continuous watering for 10 minutes; the sample rotates 90° after 5 minutes of test
b. Sprinkler test
Test equipment: hand-held splashing test device,
Place the specimen: Place the parallel distance from the top of the test to the nozzle of the hand-held nozzle between 300mm and 500mm. Test conditions: The baffle with counterweight should be installed during the test. The water flow rate is 10L/min.
Test time: According to the surface area of ​​the shell of the tested sample, it is 1 min per square meter (excluding the installation area), and the minimum is 5 min.
(4) IPX4K
Test Name: Pressure Swing Tube Rain Test Equipment: Pendulum Tube Rain Test
Place the sample: Select the appropriate radius of the oscillating tube, so that the height of the sample table is in the diameter of the oscillating tube, place the sample on the sample table so that the distance from the top of the sample to the sample water outlet is less than 20mm, and the sample table does not rotate.
Test conditions: The water flow rate is calculated as the number of spray holes in the pendulum tube, each hole is 0.6±0.5L/min. The water spray area was sprayed on the spray hole in the 90° arc on both sides of the midpoint of the pendulum pipe to the sample. The sample was placed in the center of a semi-circular tube. The oscillating tube oscillates 180° along both sides of the vertical, totaling about 360°. Each swing (2×360°) is about 12s. Test pressure: 400kPa
Test time: The sample rotates 90° after 5 minutes of test
b, sprinkler type splash test
Test equipment: hand-held splashing water splash test device
Specimen placement: The baffle with counterweight should be removed on the equipment so that the parallel distance between the top of the test and the nozzle of the hand shower is between 300mm and 500mm.
Test conditions: The baffle with counterweight should be installed during the test. The water flow rate is 10L/min.
Test time: According to the surface area of ​​the shell of the tested sample, it is 1 min per square meter (excluding the installation area) at least 5 min.
(5) IPX5
Method name: Water spray test
Test Equipment: The inner diameter of the nozzle is 6.3mm
Test conditions: The distance between the test sample and the water jet is 2.5~3m, and the water flow rate is 12.5L/min (750L/h);
Test time: According to the surface area of ​​the shell of the tested sample, it is 1 min per square meter (excluding the installation area) at least 3 min.
(6) IPX6
Method name: Strong water spray test;
Test equipment: the inner diameter of the nozzle is 12.5mm;
Test conditions: The distance between the test sample and the water spray nozzle is 2.5~3m, and the water flow rate is 100L/min (6000L/h); Test time: Calculated according to the surface area of ​​the shell of the tested sample, 1min per square meter (excluding installation area) At least 3min.
(7) IPX7
Method name: Short-term flooding test; Test equipment: Immersion tank.
Test conditions: The size should be such that after the sample is placed in the immersion tank, the distance from the bottom of the sample to the water surface is at least 1 m. The distance from the top of the sample to the water surface is at least 0.15m. Test time: 30min.
(8) IPX8
Method name: continuous diving test;
Test equipment test conditions and test time: negotiated by the supply and demand (sales) parties, the severity should be higher than the IPX7.
(9) IPX9
Method name: High pressure injection test
Test equipment: the inner diameter of the nozzle is 12.5mm;
Test conditions: spray angle: 0°, 30°, 60°, 90° (4 positions); number of spray holes: 4; sample table rotation speed: 5±1r.pm; distance is 100-150mm, each Position 30 seconds; Flow rate is 14~16L/min, spray pressure is 8000~10000kPa, water temperature requirement is 80±5°C Test time: 30 seconds x 4 seconds for each position 120 seconds
