Programmable resonant tube rain boxAlso known as waterproof test box, waterproof test box is divided into different structures according to different IPX standards, such as IPX3/IPX4 is the test box structure (box type for short), IPX5/IPX6 is the laboratory structure and IPX7/IPX8 is a water tank structure. Therefore, the box-shaped rain test box is a waterproof test box with a rating of IPX3/IPX4. Now published by QINSUN Technology, I will tell you the detailed requirements of the IPX3 and IPX4 standards.
Method name: rain test.
a. Swing pipe spray test:
Test device: pendulum water spray test.
Sample placement: choose a swing tube with appropriate radius, so that the height of the sample stage matches the diameter of the swing tube, place the sample on the sample stage so that its top reaches the sample nozzle Shuikou, the distance is not greater than 200mm and the sample stage does not rotate.
Test conditions: Water flow rate according to swing pipe Calculated from the number of water spray holes per hole is 0.07L/min. When you spray water, spray water from the water spray holes in the 60°BEyes on either side of the center point of the swing tube on the sample. The sample to be tested is placed in the center of the semicircle of the swivel tube. The swing tube swings 60° on either side of the vertical line, for a total of 120°. Each swing (2×120°) takes about 4s.
Test pressure: 400kPa.
Test time: continuous water jet for 10 minutes; sample rotated 90° after 5 minutes test.
b. Nozzle spray test:
Test Device: Portable Water Splash Test Device.
Test conditions: A During the test, a baffle plate with a counterweight should be installed and the water flow rate should be 10 l/min.
Test time: Calculated according to the surface of the test pattern
, 1 minute per square meter (excluding installation area) , 5 minutes.
wellme the method: splash test.
a. Ram Splash Test:
test device andnd Sample placement: Choose a swing tube with an appropriate radius so that the height of the sample stage matches the diameter of the swing tube Place the sample on the sample stage so that the distance from the top to the sample water nozzle is no more than 200mm and the sample stage does not rotate.
test conditions: The water flow rate is calculated by the number of swivel tube spray holes, and each hole is 0.07L/min; the spray area is to spray water from the spray hole in the 90° arc on both sides of the center point of the tubeSample The sample to be tested is placed in the center of the semi-circle of the swing tube. The swing tube swings 180° on either side of the vertical line, approximately 360° in total. Each swing (2×360°) approx. 12s.
test time: same as point a of IPX3 in point (3) above (i.e. 10 min).
b. Nozzle spatter test:
Test device: Portable water splash test device.
Sample placement: The counterweight baffle installed on the instrument should be removed so that the parallel distance from the top of the test to the nozzle of the hand nozzle is between 300mm and 500mm.
Test conditions: The belt should be installed during the test. The balance weight baffle, the water flow rate is 10L/min.
Test time: calculated according to the surface of the sample shell tested, 1 min per square meter (excluding the installation area), at least 5 min.
