Rain Chamber

Test name

Vertical water dripping test

Sample position

a.Place sample on the rotation table with adjustable 1-17r/min             b.Distance between the top side of the sample and the spout less than 200mm

Test condition

The water dripping rate is 1+0.5 mm/min,spacing between dripping hole 20mm

Test time

10 min

Grade

IPX2

Test name

15° water dripping test

Sample position

a.15 angle between one side of the sample and the vertical line         b.Distance between the top side of the sample and the spout less than 200mm.   c.Turn to test another side  and repeat it 4 times.

Test condition

the water dripping rate is 3+0.5 mm/min,spacing between dripping hole 20mm

Test time

4×2.5 min(total 10 min)

Grade

IPX3

Test name

Water pouring test

Test method

Oscillated water pouring test device

Sample placement

a.Select pendulum tubes (F16mm) with appropriate radius(0.4/0.6m/0.2/0.8/1.0/1.2/1.4/1.6m) and make the sample table height equals to the diameter of pendulum tubes .

b.Place sample on the table(does not move) and dstance between the top side of the sample and the spout less than 200mm.

Test condition

Water flow rate is calculated on the basis of the number of the spray hole of the pendulum tubes, each hole equals to 0.07 L/min.During testing, the spray hole spray water to the sample on both side of the midpoint of the pendulum tubes with 60°swinging, and the sample is placed in the center of the semicircle of tubes. The tube swings 60°respectively back and forth, total 120. It takes about 4s to swing (2×120°) once a time.

Test time

b.Place sample on the table(does not move) and dstance between the top side of the sample and the spout less than 200mm.

Test condition

Water flow rate is calculated on the basis of the number of the spray hole of the pendulum tubes, each hole equals to 0.07 L/min.During testing, the spray hole spray water to the sample on both side of the midpoint of the pendulum tubes with 90°swinging, and the sample is placed in the center of the semicircle of tubes. The tube swings 180°respectively,total 360°.It takes about 12s to swing (2×360°) once a time.
