Sample placement: place the sample on the rotating sample table at 1r/min according to the normal working position of the sample, and the distance from the top of the sample to the dripping mouth shall not be greater than
Duration: 10 min
⑵IPX 2
Method name: inclined 15 ° drip test
Test equipment: drip test device
Specimen placement: make one surface of the specimen form a 15 ° angle with the vertical line, and the distance from the top of the specimen to the drip mouth shall not be greater than
Test conditions: water drop is
Duration: 4 × 2.5 min (10 min in total)
⑶IPX 3
Method name: water sprinkling test
Test method:
a。 Pendulum type water sprinkling test
Test equipment: swing tube water sprinkling and splashing test device
Sample placement: select a swing tube with an appropriate radius, make the height of the sample table at the position of the diameter of the swing tube, place the sample on the sample table, make the distance from its top to the sample spray nozzle not more than
Test conditions: the water flow is calculated according to the number of spray holes in the swing tube, and each hole is
Test time: continuous sprinkling for 10 min
b。 Sprinkler type water spraying test
Test equipment: hand-held water sprinkling test device
Specimen placement: make the parallel distance between the top of the test and the nozzle of the hand-held nozzle between
Test conditions: the baffle with counterweight shall be installed during the test, and the water flow is
Test time: 1 min per square meter (excluding the installation area) based on the surface area of the tested sample shell, at least 5 min
⑷IPX 4
Method name: water splash test
Test method:
a. Pendulum type water splash test
Test equipment and sample placement: 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 spraying area is the water spraying from the water spraying holes in the 90 ° arc segments on both sides of the midpoint of the swing pipe to the sample. The sample is placed in the center of the semicircle of the pendulum tube. The pendulum tube swings 180 ° along both sides of the vertical line, about 360 ° in total. Each swing (2 × 360 °) about 12s
Test time: the same as that of IPX 3 (a) (10 min).
b. Sprinkler type water splash test

Test conditions: remove the baffle with counterweight installed on the equipment, and the rest are the same as the above IPX 3 (b);
Test time: The test time is the same as that of IPX 3 (b) above, that is, 1 min per square meter (excluding the installation area) based on the surface area of the tested sample shell, and at least 5 min
⑸IPX 5
Method name: Water spray test
Test equipment: inner diameter of nozzle nozzle is
Test conditions: make the distance between the test sample and the spray nozzle
Test time: 1 min per square meter (excluding the installation area) calculated according to the surface area of the tested sample shell, at least 3 min
⑹IPX 6
Method name: Strong water spray test;
Test equipment: inner diameter of spray nozzle is
Test conditions: make the distance between the test sample and the water spray nozzle
Test time: 1 min per square meter (excluding the installation area) calculated according to the surface area of the tested sample shell, at least 3 min
⑺IPX 7
Method name: Short time immersion test
Test equipment and test conditions: immersion tank. The size shall be such that the distance from the bottom of the sample to the water surface is at least
Test time: 30 min
