IPXX Grade waterproof test details are as below:
Method name: Vertical drip test
Test equipment: dripping test device
Sample placement: Place the sample in the normal working position on a rotating sample stage at 1r/min. The distance from the top of the sample to the dripping port shall not be greater than 200mm.
Test conditions: dripping volume is 1.0±0.5mm/min
Duration: 10 minutes
Method name: Tilt 15° drip test
Test equipment: dripping test device
Sample placement: Make one surface of the sample form an angle of 15° with the vertical line, and the distance from the top of the sample to the drip port shall not be greater than 200mm. After each test of one side, switch to another side, a total of four times.
Test conditions: dripping volume is 3.0±0.5 mm/min
Duration: 4×2.5 min (10 min in total)
Method name: Water spray test
experiment method:
a. Oscillating tube water spray test
Test equipment: Swing tube type water splash test device
Sample placement: Select a pendulum tube with an appropriate radius so that the height of the sample table is at the diameter of the pendulum tube. Place the sample on the sample table so that the distance from the top to the sample water nozzle is no more than 200mm and the sample table does not rotate.
Test conditions: The water flow rate is calculated based on the number of spray holes in the swing pipe. Each hole is 0.07 L/min. When water is sprayed, the water spray holes in the 60° arc segments on both sides of the midpoint of the swing pipe are sprayed towards the sample. The tested sample is placed in the center of the semicircle of the pendulum tube. The swing tube swings 60° on each side of the vertical line, for a total of 120°. Each swing (2×120°) about 4s
Test time: continuous water spraying for 10 minutes
b. Sprinkler type water test
Test equipment: hand-held water splash test device
Sample placement: Make the parallel distance from the top of the test to the water nozzle of the handheld nozzle between 300mm and 500mm
Test conditions: A baffle with a counterweight should be installed during the test, and the water flow rate is 10 L/min.
Test time: Calculated based on the surface area of the shell of the sample being tested, 1 minute per square meter (excluding installation area), minimum 5 minutes
Method name: splash water test
experiment method:
a. Oscillating tube splash test
Test equipment and specimen placement: are the same as the above IPX 3 paragraph a;
Test conditions: Except for the following conditions, they are the same as the above IPX 3 paragraph a; the water spray area is the water spray from the water spray holes in the 90° arc sections on both sides of the midpoint of the swing pipe to the sample. The tested sample is placed in the center of the semicircle of the pendulum tube. The swing tube swings 180° on both sides of the vertical line, for a total of about 360°. Each swing (2×360°) about 12s
Test time: The same as the above IPX 3 paragraph a (i.e. 10 minutes).
b. Nozzle splash test
Test equipment and specimen placement: are the same as those in paragraph b of IPX 3 above;
Test conditions: Remove the baffle with a counterweight installed on the equipment, and the rest are the same as the above IPX 3 paragraph b;
Test time: The same as paragraph b of IPX 3 above, that is, calculated based on the surface area of the shell of the sample being tested, 1 minute per square meter (excluding installation area), at least 5 minutes
Method name: Water spray test
Test equipment: The inner diameter of the water outlet of the nozzle is 6.3mm
Test conditions: The distance between the test sample and the water spout is 2.5m ~ 3m, and the water flow is 12.5 L/min (750 L/h)
Test time: Calculated based on the surface area of the shell of the sample being tested, 1 minute per square meter (excluding installation area), at least 3 minutes
Method name: Strong water spray test;
Test equipment: The inner diameter of the water outlet of the nozzle is 12.5 mm
Test conditions: The distance between the test sample and the water spout is 2.5m ~ 3m, and the water flow is 100 L/min (6000 L/h)
Test time: Calculated based on the surface area of the shell of the sample being tested, 1 minute per square meter (excluding installation area), at least 3 minutes
Method name: Short-time immersion test
Test equipment and test conditions: immersion box. The size should be such that after the sample is placed in the immersion box, the distance from the bottom of the sample to the water surface is at least 1m. The distance from the top of the specimen to the water surface is at least 0.15m
Test time: 30 minutes
Method name: Continuous diving test;
Test equipment, test conditions and test time: The severity level should be higher than IPX 7 as agreed between the supply and demand parties (buyers and sellers).
Note: In addition, many outdoor electronic products also emphasize floating capabilities. |
