National standard for rain test box (IPX0-8)
According to the requirements of Article 13.2.3 of GB4706, GB4208, GB2423 and other relevant standards, the rain test box is used to test the protective performance of rainproof devices. IP protection equipment includes the following equipment: Drip rainproof device (IPX1/IPX2), Swivel pipe rainproof device (IPX3/IPX4), Strong flushing rainproof device (IPX5

International standard waterproof registration IP from 0 to 8 Divided into 9 levels .
Waterproof level (the second X indicates)
0: No protection
1: There is no effect when water drops into the cover.
2: When the cover drops to 15 degreesaden is tilted , Water droplets enter Using the case has no effect.
3: Water or rain does not affect the 60 degree angle to the case.
4: Liquid hitting the case from either direction housing splash, has no harmful effect.
5: Rinse with water, without any damage.
6: It can be used in the cabin.
7: It can be soaked in water in a short time (1m) be immersed
8: It can be immersed in water for a long time under a certain pressure.
br>For example: a scale or display instrument is marked IP65, which means that the product can completely prevent dust from entering and wash away any damage done to me. IPXX waterproof test regulations.

(1) IPX1
Method: vertical drop test
Equipment: drop test device.
Sample placement: place the sample on a 1r/min rotating sample table according to the normal working position and the away from the top ofthe sample to the drop opening should not exceed 200mm.
Test condition: the amount of falling is 10.5mm/min.
Duration: 10 minutes

(2) IPX2
Method : Drop test at an angle of 15°.
Equipment: Dripping water test device.
Sample placement: Have one surface of the sample at an angle of 15° to the vertical, and the distance from the top of the sample to the water drop is not more than 200mm. After each test, replace the other surface four times.
Test conditions: The amount of dripping is 30.5mm/min.
Duration: 4×2.5 minutes (10 minutes in total)

(3) IPX3
Method: Water spray test
Test method:
Answer: Pendulum shower test
Test equipment: Pendulum water spray test device.
Test placement: Choose a pendulum pipe with a suitable radius so that the height of the sample table is within the height of the swing tube Place the sample by the diameter on the sample platform so that the distance from the top sample nozzle does not exceedthere is then 200mm, and the sample table does not rotate.
Test conditions: The water flow rate is calculated according to the number of spray holes, and each hole is 0.07L/min. When spraying water, water is sprayed onto the sample from the nozzle holes on both sides of the 60° arc portion of the center of the swing tube. The test sample is placed in the center of the semicircle. The pendulum swings 60° on either side of the vertical, for a total of 120°. Each swing (2 x 120) lasts approximately 4 seconds.
Test time: continuous watering for 10 minutes.
b: Sprinkler shower test
Test equipment: manually operated splash water test device.
Sample Placement: Make the parallel distance from the top of the test to the water nozzle of the hand nozzle between 300mm and 500mm.
Test conditions: During the test, a counterweight baffle shall be installed and the water flow rate shall be 10 l/min.
Test time: calculated based on the surfacek of the tested sample scale, 1min/m2 (excluding the installation area), minimum 5min.

(4) IPX4
Method: Splash test
Test method:
Answer: Swivel tube splash test
Test equipment and sample placement: Same as above IPX 3(A);
Test conditions: except for the following conditions, same as above IPX 3(A); the water spray area is 90 degrees on both sides of the center point of the swing pipe, and the water spray holes in the arc section spray water to the sample. The test sample is placed in the center of the semicircle. Both sides of the vertical line swing 180°, about 360° in total. Each swing (2×360) lasts about 12 seconds.
Test Time: Same as Section A of IPX3 above (ie 10 minutes).
b: Water Splash Test
Equipment and Sample Placement: Same as IPX3 section above;

Test conditions: Remove and install the schot with counterweight, and the rest is the same as the above IPX3 section;
Test time: The same as the above IPX3 section b, that is, 1 minute per square meter (excluding the installation area) for at least 5min, calculated on the basis of the area of ​​the shell of the tested sample.

(5) IPX5
Method: water spray test
Test equipment: the inner diameter of the nozzle is 6.3mm
Test conditions: the distance between the sample and the nozzle is 2.5m ~ 3m, the water flow rate is 12.5L/min (750L/h).
Test time: 1min per square meter (excluding the installation area), minimum 3min, calculated based on the area of ​​the tested sample tray.

(6) IPX6
Method: Strong water spray test
Test equipment: The inner diameter of the water nozzle is 12.5mm..
Test conditions: The distance between the sample and the water nozzle is 2, 5 m ~ 3 m, the water flow rate is 100 l/min (6000 l/h).
Test time: 1min per squaremeters (excluding the installation area), minimum 3min, calculated based on the area of ​​the tested sample tray.

7) IPX7
Method: short-term immersion test
Test equipment and test conditions: immersion tank. The dimensions must ensure that the distance from the bottom of the sample to the water surface is at least 1 m after the sample has been placed in the immersion tank. The distance from the top of the sample to the water surface is at least 0.15 meters
Test time: 30 minutes

(8)IPX8
Method: continuous diving test
