The experiment of IP waterproof test grades

The experiment of IP waterproof test grades

(1) The IPX 1

Method name: Vertical drip water test

Testing equipment: Drop test device

Sample to place: According to the normal work of the sample position put on the 1 r/min rotation sample, the top sample to drop water distance not far more than 200 mm

Test conditions: Drops of water is 10.5 mm/min

Duration: 10 min

(2) The IPX 2

The method name: Tilt 15 ° drip test

Testing equipment: Drop test device

A sample to be placed: Make sample surface vertical into 15 ° angle, sample top to drop port distance is no more than 200 mm. After each surface test, test another side, a total of four times.

Test conditions: Drops of water for 30.5 mm/min

Duration: 4 x 2.5 min (10 min)

(3) The IPX 3

Method name: Water spray test

Test method:

A. Swing Pipe Water Spray Test

Testing equipment: Swing pipe water spray test splash water test device

Place sample: Select the appropriate swing pipe radius, place the sample mesa height on the swing pipe’s diameter position, make the distance from the top to the sample water is not more than 200 mm, samples stage not rotating.

Test conditions: Calculate water flow by each number of blowhole, every hole is 0.7 L/min, water spray, make the both blowhole to spray to the samples. Place the samples into the semicircle center. Each side of swing pipe along the vertical swings 60 ° , 120° in total. Each time swing (2 x 120 °) about 4 s

Test time: Continue spray water test

B. Nozzle type water spray test

Testing equipment: Hand-held spray water splashing water test device

Sample place: Make the top to the handheld shower nozzle water-jet parallel distance between 300 mm to 500 mm

Experiment conditions: When test it should be install with balance plate

Test time: According to the shell surface area calculation, test sample for 1 min per square meter area (not including installation), at least 5 min.

(4) The IPX 4

Method name: Splash water test

Test method:

A. Swing pipe splash water test(Waterproof Tester(JL-X))

Test equipment and sample to place: As the same as IPX3

Test conditions: In addition to the above conditions of IPX3 are the same; Each side of swing pipe along the vertical swings 180° , 360° in total. Each time swing (2 x 360 °) about 12s

The test time: The same as IPX3(that is 10 min).

B. Nozzle type splash water test

Test equipment and sample placed: The same as IPX 3B;

Test conditions: Dismantle the baffle, the rest is the same as the IPX 3B;

Test time: With the same as IPX 3B

(5) The IPX 5

Method name: Water spray test

Testing equipment: Water orifice diameter of nozzle is 6.3 mm

Test conditions: Make the test distance between sample and water-jet as 2. 5 m ~ 3 m, water flow is 12.5 L/min (750 L/h)

Test time: According to the shell surface area calculation, test sample of every square metre is 1 min (not including installation area) at least 3 min

(6) The IPX 6

Method name: Strong hydraulic test

Testing equipment: Nozzle water orifice diameter is 12.5 mm

Test conditions: Make the test distance between sample and water-jet as 2.5 m ~ 3 m, water flow is 100 L/min (6000 L/h)

Test time: According to the shell surface area calculation, test sample of every square meter is 1 min (not including installation area) at least 3 min

(7) The IPX 7

The method name: Short water immersion test

Test equipment and test conditions: Immersion tank. Its size should be make the sample into the immersion tank, the surface distance to the bottom of sample at least 1 m. The sample top distance to the surface at least 0.15 m.

The test of time: 30 min

(8) The IPX 8

Method name: Continue diving test

Test equipment, test conditions and test time: Agreed upon by the buyer and the seller,its harsh degree should be higher than the IPX 7.
