1. IPX1
Method name: Vertical drip test
Test equipment: drip test device
Sample placement: placed on the rotating table at 1r/min according to the normal working position of the sample, the distance from the top of the sample to the drip port is not more than 200mm
Test conditions: the drip volume is 10.5 mm min
Duration: 10 min
2. IPX 2
Method name: Incline 15° drip test
Test equipment: drip test device
Sample placement: Make a surface of the sample at an angle of 15° to the vertical, and the distance from the top of the sample to the drip port should not exceed 200mm. After each test, change the other side for a total of four times.
Test conditions: the drip volume is 30.5 mm/ min
Duration: 4x2.5 min (total 10 min)
3. IPX 3
Method name: water spray test
a. Swing tube type water spray test
Sample placement: Select the swing tube of an appropriate radius so that the height of the sample table is at the diameter of the swing tube. Place the sample on the sample table so that the distance from the top of the sample to the sample spout is not more than 200mm, and the sample table does not rotate.
Test conditions: The water flow rate is calculated according to the number of spray holes of the pendulum tube, each hole is 0.07 L/min. When water is sprayed, the water spray holes in the 60° arcs on both sides of the pendulum tube are sprayed toward the sample. The test sample is placed in the center of the semicircle of the pendulum tube. The pendulum tube swings 60° on both sides of the vertical line, a total of 120°, each swing (2x120°) about 4s
Test time: continuous watering for 10 min
b. Sprinkler test
Test equipment: hand-held water splash test machine
Sample placement: make the parallel distance between the top of the test and the nozzle of the hand nozzle between 300mm and 500mm
Test conditions: A baffle with a counterweight should be installed during the test, with a water flow of 10 L/min.
Test time: calculated according to the surface area of the tested sample shell, 1 min per square meter (excluding installation area), at least 5 min
