Rain Test ChamberAlso known as waterproof test box, waterproof test box is divided into different structures according to different IPX level standards. For example, IPX3/IPX4 is the test box structure (referred to as box type), IPX5/IPX6 is the laboratory structure, and IPX7/IPX8 is the water tank structure. So the box type rain test box is a waterproof test box with a rating of IPX3/IPX4. Now, Liu Qin Technology will explain to you the detailed requirements of IPX3 and IPX4 standards.

(3) IPX3

Method name: Rain test.

a. Swing tube water pouring test:

Experimental equipment: Swing tube water splashing test.

Sample placement: Select a swing tube with an appropriate radius, so that the height of the sample table is at the diameter position of the swing tube. Place the sample on the sample table so that the distance from its top to the sample spray nozzle is not greater than 200mm, and the sample table does not rotate.

Experimental conditions: The water flow rate is calculated based on the number of spray holes in the swing pipe, with each hole being 0.07 L/min. When pouring water, the water sprayed from the spray holes on both sides of the midpoint of the swing tube in a 60 ° arc segment is directed towards the sample. The sample is placed at the center of the half circle of the pendulum tube. The swinging tube swings 60 degrees on both sides along the vertical line, for a total of 120 degrees. Each swing (2 × 120 °) takes about 4 seconds.

Test pressure: 400kPa.

Test time: Continuous watering for 10 minutes; Rotate the sample 90 ° after 5 minutes of testing.

b. Nozzle type water spray test:

Test equipment: Handheld water splashing test device.

Sample placement: Ensure that the parallel distance between the top of the test and the handheld nozzle is between 300mm and 500mm.

Test conditions: A baffle with a balance weight should be installed during the test, with a water flow rate of 10L/min.

Test time: Calculated based on the surface area of the tested sample shell, 1 minute per square meter (excluding installation area), 5 minutes.

(4）IPX4

Method name: Splash test.

a. Swing tube splash test:

Test equipment and sample placement: Select a swing tube with an appropriate radius, so that the height of the sample table is at the diameter position of the swing tube. Place the sample on the sample table so that the distance from its top to the sample spray nozzle is not greater than 200mm, and the sample table does not rotate.

Experimental conditions: The water flow rate is calculated based on the number of spray holes in the swing pipe, with each hole being 0.07 L/min; The spraying area is the water sprayed from the spraying holes within the 90 ° arc segments on both sides of the midpoint of the swing pipe towards the sample. The sample is placed at the center of the half circle of the pendulum tube. The swinging tube swings 180 ° on both sides along the vertical line, for a total of approximately 360 °. Each swing (2 × 360 °) lasts about 12 seconds.

Test time: Same as IPX3 clause a in (3) above (i.e. 10 minutes).

b. Spray nozzle splash test:

Test equipment: Handheld water splashing test device.

Sample placement: The baffle with balanced weight installed on the equipment should be removed, so that the parallel distance from the top of the test to the handheld nozzle spray port is between 300mm and 500mm.

Test conditions: A baffle with a balance weight should be installed during the test, with a water flow rate of 10L/min.

Test time: calculated based on the surface area of the tested sample shell, with a minimum of 5 minutes per square meter (excluding installation area).
