(3) IPX3

Method name: rain test (rain test equipment)

A. water spray test with swing tube

Test equipment: swing tube water splashing test

Sample placement: select a swing tube with appropriate radius to make the height of the sample table top on the swing tube diameter. Place the sample on the sample table so that the distance from its top to the sample water nozzle is not more than 200 mm, and the sample table does not rotate.

Test conditions: the water spray quantity of water flow near the swing pipe is also calculated, and each is 0.07l/min. When pouring water, spray water from the spray holes in the 60 ° arc section on both sides of the central point of the pipe to the sample. Place the sample in the semicircle center of the pendulum tube. The swing pipe swings 60 ° along both sides of the vertical line, 120 ° in total. Each swing (2 × 120 °) is about 4 s.

Test pressure: 400kPa

Test time: continuous watering for 10min; sample rotation 90 ° after 5min

B. sprinkler type water spray test

Test equipment: hand-held splash test device,

Sample placement: make the parallel distance between the top of the test and the nozzle of the hand-held nozzle between 300 mm and 500 mm

Test conditions: the baffle with balance weight shall be installed during the test, and the water flow shall be 10L / min

Test time: calculated according to the surface area of the shell of the tested sample, 1min per square meter (excluding the installation area), 5min at least.

(4) ipx4k (rain test equipment)

Test Name: pressure swing pipe rain test

Test equipment: pendulum type rain test

Sample placement: select a swing tube with appropriate radius to make the height of the sample table top at the position of the swing tube diameter. Place the sample on the sample table so that the distance from the top to the sample nozzle is not more than 20 mm, and the sample table does not rotate.

Test conditions: the water flow is calculated according to the number of spray holes of the swing pipe, and each hole is 0.6 ± 0.5l/min. The spray area is the spray water from the spray holes in the 90 ° arc section on both sides of the middle point of the pendulum tube to the sample. Place the sample in the semicircle center of the pendulum tube. The pendulum tube swings 180 ° along both sides of the vertical line, about 360 ° in total. Each swing (2 × 360 °) is about 12s.

Test pressure: 400kPa

Test time: sample rotates 90 ° after 5 minutes of test
