Seals IP56 protection class testing standards

IPxx dust and waterproof rating

Dust levels (first X represents) Waterproof grade (second X represents)

0: No protection

1: to prevent large solids invasion

2: to prevent intrusion of solid medium-sized

3: to prevent intrusion into the small solid

4: to prevent solid objects greater than 1mm into the

5: to prevent the accumulation of harmful dust

6: completely prevent dust entering

0: No protection

1: No effect of water droplets dripped into housing

2: when the housing is tilted to 15 degrees, no effect of water droplets drip into the housing

3: no effect of water or rain water from the corner to the housing 60 of the

4: Liquid splashed from any direction, there is no harm to the housing impact

5: wash with water without any harm

6: can be used within the cabin environment

7: resistant to immersion in a short time (1m)

8: prolonged immersion in water at a certain pressure

Example: There are scales or display instrument labeled as IP65, indicates that the product can completely prevent dust entering and can be washed with water without any harm.

IPXX water level in experiments on requirements.

(1) IPX 1

Method name: vertical drip test

Test equipment: drip test device

Sample Placement: normal operating position by placing the sample in order to rotate the sample 1r / min of the stage, at the top of the sample to the dripping mouth of not more than 200mm

Test conditions: dripping amount of 10.05 mm / min

Duration: 10 min

(2) IPX 2

Method name: 15 ° tilt drip test

Test equipment: drip test device

Sample Placement: the sample surface and perpendicular to a 15 ° angle, the top of the sample to the dripping mouth of not more than 200mm. After each test a surface finish, for another side, a total of four times.

Test conditions: dripping amount of 30.5 mm / min

Duration: 4 × 2.5 min (total 10 min)

(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

Method name: splashing water test

Test method:

a. pendulum tube splashing water test

Test equipment and sample placement: IPX a paragraph 3 above are the same;

Test conditions: In addition to the above conditions, and IPX a paragraph 3 of the above are the same; spray water area of ​​the midpoint of each side of the pendulum tube within 90 ° arc segment blowholes sprayed samples. Test samples were placed in a semicircle center pendulum tube. Placed along the vertical tube on each side of the swing 180 °, a total of about 360 °. Each swing (2 × 360 °) to about 12s

Test time: IPX of a paragraph above three are the same (ie, 10 min).

b. nozzle type splash water test

Test equipment and sample placement: with paragraph 3 of the above IPX b are the same;

Test conditions: Install the bezel with balance weights on the device removed, the rest of the paragraph 3 of the above IPX b are the same;

Test time: IPX b above, paragraph 3 of the same, ie sample shell surface area calculated per square meter for 1 min (not including installation area) at least 5min

(5) IPX 5

Method name: the water spray test

Test equipment: nozzle spout diameter of 6.3mm

Test conditions: the test sample to the spout of 2.5m ~ 3m, water flow rate of 12.5 L / min (750 L / h)

Test time: According to sample shell surface area calculated per square meter for 1 min (not including installation area) at least 3 min

(6) IPX 6

Method name: strong water spray test;

Test equipment: spout diameter is 12.5 mm nozzle

Test conditions: the test sample to the spout of 2.5m ~ 3m, water flow rate of 100 L / min (6000 L / h)

Test time: According to sample shell surface area calculated per square meter for 1 min (not including installation area) at least 3 min

(7) IPX 7

Method name: short-term immersion test
