(3) IPX 3
Method name: water spray test
Test method:
a. Put water spray test tube
Test equipment: swing tube splashing water spray test device
Sample Placement: Select the appropriate radius of the pendulum tube, placed in the sample tube diameter table height position, the sample on the sample stage, so that the top of the spout from the sample is not more than 200mm, the sample stage does not rotate.
Test conditions: the number of holes sprinkler water flow by calculating the oscillating tube, each hole is 0.07 L / min, when watering, swing pipe sprinkler spray holes on each side of the midpoint within a 60 ° arc sprayed samples. Test samples were placed in a semicircle center pendulum tube. Placed along the vertical tube on each side of the swing 60 °, a total of 120 °. Each swing (2 × 120 °) to about 4s
Test time: 10 min continuous watering
b. Nozzle type water spray test
Test Equipment: Handheld water spray splashing water test device
Sample Placement: to make the top of the test at between 300mm to 500mm handheld spray nozzle distance parallel port
Test conditions: baffles should test installation with balance weights, water flow was 10 L / min
Test time: According to sample shell surface area calculated per square meter for 1 min (not including installation area), at least 5 min
(4) IPX 4
