PX3
Method name: rain test
a. Swing pipe water spray test
Test equipment: pendulum-type spray water splash test
Sample placement: Choose a swing tube with an appropriate radius, make the height of the sample table at the diameter of the swing tube, place the sample on the sample table, and make the distance from the top to the sample water jet is not more than 200mm, and the sample table does not rotate.
Test conditions: The water flow is calculated according to the number of water spray holes in the swing pipe, and each hole is 0.07 L/min. When spraying water, the water spray from the water spray holes in the 60° arc sections on both sides of the midpoint of the pendulum tube is sprayed to the sample. The sample to be tested is placed in the center of the semicircle of the pendulum tube. The swing tube swings 60° on both sides of the vertical line, a total of 120°. Each swing (2×120°) is about 4s.
Test pressure: 400kPa; Test time: continuous water spray for 10min; sample rotated 90° after 5min test
b. Sprinkler water spray test
Test equipment: hand-held water spray test device,
Specimen placement: Make the parallel distance from the top of the test to the nozzle of the hand-held nozzle between 300mm and 500mm
Test conditions: During the test, a baffle with a counterweight should be installed, and the water flow should be 10L/min
Test time: Calculated according to the surface area of ​​the shell of the tested sample, 1min per square meter (excluding installation area), at least 5min.
