- May 07, 2018 -

IP test 



The waterproof test includes the second characteristic digits 1 to 8, that is, the protection level codes are IPX1 to IPX8.

Grade waterproof

(1) IPX 1

Method name: vertical drop test

Test equipment: drip test apparatus

Place the sample: Place the sample on the rotating sample stage with 1r/min according to the normal working position of the sample. The distance from the top of the sample to the drip opening should not exceed 200mm.

Test conditions: drip volume 1.0±0.5mm/min

Duration: 10 min

(2) IPX 2

Method name: tilted 15° drop test

Test equipment: drip test apparatus

Place the specimen: Make one surface of the specimen at an angle of 15° to the vertical, and the distance from the top of the specimen to the drip nozzle should not exceed 200mm. After each face is tested, change it to another face, four times in total.

Test conditions: drip volume is 3.0±0.5 mm/min

Duration: 4 x 2.5 min (10 min total)

(3) IPX 3

Method name: Water splash test

experiment method:

a. Plunge pipe type watering test

Test equipment: pendulum tube type water splash test device

Place the sample: Select the appropriate radius of the oscillating tube, so that the height of the sample table is in the position of the diameter of the oscillating tube. Place the sample on the sample table so that the distance from the top of the sample to the sample water outlet is no more than 200mm. The sample table does not rotate.

Test conditions: The water flow rate is calculated as the number of spray holes in the oscillating tube. Each hole is 0.07 L/min. When water is poured, the water spray holes in the 60° arc section on both sides of the midpoint of the oscillating pipe are sprayed to the sample. The sample was placed in the center of a semi-circular tube. The oscillating tube oscillates along both sides of the vertical 60°, 120° in total. Each swing (2×120°) for about 4s

Test time: continuous watering 10 min

b. Sprinkler test

Test Equipment: Hand-held splashing water splash test device

Specimen placement: The parallel distance from the top of the test to the nozzle of the hand shower is between 300mm and 500mm

Test conditions: The baffle with counterweight should be installed during the test. The water flow rate is 10 L/min.

Test time: Calculated according to the surface area of the shell of the tested sample, 1 min per square meter (excluding installation area), min. 5 min

(4) IPX 4

Method name: water shower test

experiment method:

a. Pendulum tube type splash test

Test equipment and specimen placement: Same as in paragraph a of IPX 3 above;

Test conditions: Except for the following conditions, it is the same as the above paragraph of IPX 3, and the water spray area is sprayed on the spray hole in the 90° arc section on both sides of the midpoint of the pendulum pipe. The sample was placed in the center of a semi-circular tube. The oscillating tube oscillates 180° on both sides of the vertical, totaling about 360°. Each swing (2×360°) about 12s

Test time: Same as above for IPX 3 (ie 10 min).

b. Sprinkler test

Test Equipment and Sample Placement: Same as in paragraph b of IPX 3 above;

Test conditions: remove the baffle with balance weights from the equipment, and the rest are the same as those of the above IPX 3 b;

Test time: the same as the above IPX 3 b, that is, according to the surface area of the shell of the tested sample, 1 min per square meter (excluding installation area) at least 5 min

(5) IPX 5

Method name: Water spray test

Test Equipment: The inner diameter of the nozzle is 6.3mm

Test conditions: The distance between the test sample and the nozzle is 2.5m to 3m, and the water flow rate is 12.5 L/min (750 L/h).

Test time: Calculated according to the surface area of the shell of the tested sample, 1 min per square meter (excluding installation area) at least 3 min

(6) IPX 6

Method name: Strong water spray test;

Test equipment: inner diameter of spray nozzle is 12.5 mm

Test conditions: The distance from the test sample to the water outlet is 2.5m to 3m, and the water flow rate is 100 L/min (6000 L/h).

Test time: Calculated according to the surface area of the shell of the tested sample, 1 min per square meter (excluding installation area) at least 3 min

(7) IPX 7

Method name: Short-term flooding test

Test equipment and test conditions: Immersion tank. The dimensions should be such that the sample is placed in the immersion tank and the distance from the bottom of the sample to the water surface is at least 1 m. The distance from the top of the sample to the water surface is at least 0.15m

Test time: 30 min

(8) IPX 8

Method name: Continuous diving test;

Test equipment, test conditions and test time: agreed upon by the supply and demand (sales) parties, the severity of which should be higher than IPX 7.

Note: In addition, many outdoor electronic products also emphasize floating ability.

IP (INGRESS PROTECTION) protection level and waterproof test are based on the criteria are:

1) International protective and waterproof test standards drafted by IEC (International Electrotechnical Communications): International Electrotechnical Commission standard IEC 529 – 598

2) GB GB 700 – 86

3) GB 4208-2008 enclosure protection grade (IP code) and so on.

IP protection level laboratory: The laboratory that can carry out IP level testing mainly includes a testing laboratory, environmental reliability and electromagnetic compatibility testing center, aerospace environmental reliability testing and testing center, Suzhou Institute of Electrical Science and Technology, and national electrical product quality. Supervision and inspection center.
