The introduction of the IP rating of the rain test box, the waterproof level of the product also reflects the product's ability to prevent moisture and dust. Under special use conditions, the product's sealing and waterproof ability is crucial to ensure the safe use and life of the product. For this reason, the corresponding waterproof standards have been formulated internationally.
Waterproof level (indicated by the second X)
0: No protection
1: Water droplets have no effect on the shell
2: When the shell is tilted to 15 degrees, water droplets drip into the shell without effect
3: Water or rain has no effect from the 60 degree corner to the shell
4: The liquid is splashed into the shell from any direction without harm.
5: Rinse with water without any harm
6: Can be used in the cabin environment
7: Resistant to water immersion in a short time (1m)
8: Under immersion under certain pressure

Method name: Vertical drip test equipment: Drop test device Sample placement: Place the sample on the rotating sample table at 1r / min according to the normal working position of the sample. The distance from the top of the sample to the drip opening is not greater than 200mm.
Test conditions: dripping water is 10.5mm / min
Method name: Dip 15 ° Drip Test Equipment: Drip test device Sample placement: Make one surface of the sample at a 15 ° angle to the vertical line, and the distance from the top of the sample to the drip opening is not greater than 200mm. After each test, Change the other side four times.
Test conditions: dripping water is 30.5mm / min
Duration: 4 × 2.5 min (total 10 min)
Method name: Water spray test Test method:
a: Pendulum tube type water spray test equipment: Pendulum tube type water splash test device Test placement: Select a pendulum tube with an appropriate radius so that the height of the sample table surface is at the diameter of the pendulum tube, and place the sample on the sample table. Make the distance of the top sample spray nozzle not more than 200mm, and the sample stage does not rotate.
Test conditions: The water flow rate is calculated according to the number of water spray holes. Each hole is 0.07 L / min. When the water is sprayed, the water spray from the water spray holes in the 60 ° arc on both sides of the pendulum pipe is sprayed toward the sample. The test sample is placed in the center of the semicircle. The swing tube swings 60 ° on both sides of the vertical line for a total of 120 °. 4s per swing (2 × 120 °)
Test time: continuous water spray for 10min
b: sprinkler-type water spray test equipment: hand-held sprinkler test device sample placement: the parallel distance between the top of the test and the nozzle of the hand-held sprinkler is between 300mm and 500mm test conditions: a balance weight should be installed during the test Object baffle, water flow is 10L / min
Test time: Calculated according to the surface area of the tested sample shell, 1min per square meter (excluding installation area), minimum 5min
