Introduction to IPXY certification

The IP (INGRESS PROTECTION) protection level system was drafted by the IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION), which classifies electrical appliances according to their dust-proof and moisture-proof characteristics. The IP protection level is composed of two numbers. The first number indicates the level of dustproofing and preventing foreign objects from entering the electrical appliance. In order to avoid electric shock), the second number indicates the sealing degree of the appliance against moisture and water immersion, and the larger the number, the higher the protection level.

The protection level is mostly expressed by IP followed by two numbers, and the number is used to clarify the protection level.

The first digit indicates the range of the equipment's resistance to fine dust, or the degree to which people are protected from harm in a sealed environment. Represents the level to prevent the entry of solid foreign objects, the highest level is 6;

The second digit indicates how waterproof the device is. Represents the level of preventing water ingress, the highest level is 8.

IP grade waterproof classification

⑴IPX 1

Test condition: the drip volume is 1.0±0.5mm/min

Duration: 10 min

⑵IPX 2

Method name: tilt 15° drip test

Test equipment: drip test device

Sample placement: Make a surface of the sample at an angle of 15° to the vertical, and the distance from the top of the sample to the drip port should not exceed 200mm. After each test, change the other side for a total of four times.

Test condition: the drip volume is 3.0±0.5 mm/min

Duration: 4×2.5 min (total 10 min)

⑶IPX 3

Method name: water spray test

experiment method:

a. Swing tube type water spray test

Test equipment: pendulum tube spray test device

Sample placement: Select a swing tube of appropriate radius so that the height of the sample table is at the diameter of the swing tube. Place the sample on the sample table so that the distance from the top of the sample to the sample spout is not greater than 200mm, and the sample table does not rotate.

Test condition: The water flow rate is calculated according to the number of spray holes of the pendulum tube, each hole is 0.07 L/min. When spraying water, the water spray holes in the 60° arcs on both sides of the pendulum tube are sprayed toward the sample. The test sample is placed in the center of the semicircle of the pendulum tube. The pendulum tube oscillates 60° on both sides of the vertical line for a total of 120°. Each swing (2×120°) about 4s

Test time: continuous watering for 10 min

b. Sprinkler test

Test equipment: hand-held water spray test device

Sample placement: make the parallel distance between the top of the test and the nozzle of the hand nozzle between 300mm and 500mm

Test conditions: a baffle with a counterweight should be installed during the test, with a water flow of 10 L/min

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

⑷IPX 4

Method name: Water splash test

experiment method:

a. Swing tube splash test

Test equipment and sample placement: same as paragraph a of IPX 3 above;

Test conditions: Except for the conditions described below, they are the same as paragraph a of IPX 3 above; the water spray area is the water spray from the spray holes in the 90° arcs on both sides of the midpoint of the pendulum tube. The test sample is placed in the center of the semicircle of the pendulum tube. The swing tube swings 180° on both sides of the vertical line for a total of about 360°. Each swing (2×360°) about 12s

Test time: the same as paragraph a of IPX 3 above (ie 10 min).

b. Sprinkler test

Test equipment and sample placement: same as paragraph b of IPX 3 above;

Test conditions: Remove the baffle with balance weight installed on the equipment, and the rest are the same as the above b of IPX 3;

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

⑸IPX 5

Method name: water spray test

Test equipment: the inner diameter of the nozzle of the nozzle is 6.3mm

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

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

⑹IPX 6

Method name: Strong water spray test;

Test equipment: the inner diameter of the nozzle of the nozzle is 12.5 mm

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

⑺IPX 7

Method name: Short-term immersion test

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

Test time: 30 min

⑻IPX 8

Method name: Continuous diving test;

Test equipment, test conditions and test time: It is agreed between the supply and demand (sales and purchase) parties, and its severity is higher than IPX 7.

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

IP grade dustproof classification

1: Prevent large solid intrusion

2: Prevent the invasion of medium-sized solids

3: Prevent intrusion of small solids

4: Prevent solid objects larger than 1mm from entering

5: Prevent harmful dust accumulation

IP certification process

1. Data and sample review;

2. Officially open the case;

3. Test;

4. Report preparation;

5. Review and issue a formal report

Documents prepared for IP level certification

1. Application form (applicant information, manufacturer information, product information three major pieces);

2. Product manual (need to indicate the maximum ambient temperature of the product);
