Method name: rain test

a. Pendulum type water spraying test

Test equipment: pendulum type water spraying water splashing test

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