The following waterproof grade reference standards: IEC60529, GB4208, GB/T10485-2007, DIN40050-9, ISO20653, ISO16750 and other internationally applicable standards:

1. range

Waterproof test includes second companion feature number 1 to 8, ie protection class code IPX1 to IPX8

2。 Various levels of waterproof test content。

(1) IPX1

Method name: vertical drop test

Test equipment: drip test apparatus and test method

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; test duration: 10min

(2) IPX2

Method name: tilted 15° drop test

Place the sample: Make a 15° angle from the vertical line of the sample, and the distance from the top of the sample to the drip outlet shall not exceed 200mm。 After each test, change the other side for a total of four times。

Test conditions: drip volume 3。0 + 0。5 mm/min; test duration: 4 x 2。5 min total 10 min


(3) IPX3

Method name: Rain test

a. Pendulum-type pouring test

Test equipment: pendulum tube type water splash test

Place the sample: Select the appropriate radius of the oscillating tube, so that the height of the sample table is in 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 less 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 being 0。07 L/min。 When spraying water, the water spray hole in the 60° arc section on both sides of the midpoint of the pipe was 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 by 60°, for a total of 120°。 Each swing (2×120°) is about 4s。

Test pressure: 400kPa; Test time: Continuously drenched for 10min; The sample rotates 90° after 5min of test

b. Sprinkler test

Test equipment: hand-held splashing water test device,

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

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

Test time: According to the surface area of the shell of the tested sample, it is 1 min per square meter (excluding the installation area) and at least 5 min.

(4) IPX4

Method name: splash test;

a。 Pendulum tube type splash test

Test equipment and sample placement: Select a suitable radius of the oscillating tube, so that the height of the sample table in the diameter of the oscillating tube, the sample on the sample table, make the distance from the top of the sample water nozzle is not more than 200mm, the sample table Do not rotate.

Test conditions: The water flow rate is calculated as the number of water spray holes in the oscillating tube, each hole is 0。07L/min; the water spray area is spray water sprayed to the sample within the 90° arc section on both sides of the midpoint of the pendulum tube。 The sample was placed in the center of a semi-circular tube。 The oscillating tube oscillates 180° along both sides of the vertical, totaling about 360°。 Each swing (2 × 360°) about 12s。

Test time: Same as paragraph (a) of paragraph (3) IPX3 above (ie 10 min).

b。 Sprinkler test

Test equipment: hand-held splashing water test device,

Specimen Placement: The baffles with counterweights installed on the equipment should be removed so that the parallel distance between the top of the test and the nozzle of the hand shower is between 300mm and 500mm.

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

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

(5) IPX4K

Test Name: Pressure Swing Tube Rain Test

Test equipment: oscillating rain test

Place the sample: Select the appropriate radius of the oscillating tube, so that the height of the sample table is in 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 less than 200mm. The sample table does not rotate.

Test conditions: The water flow rate is calculated as the number of spray holes in the pendulum tube, each hole is 0.6 ± 0.5 L/min. The water spray area was sprayed on the spray hole in the 90° arc section on both sides of the midpoint of the pendulum pipe to the sample. The sample was placed in the center of a semi-circular tube. The oscillating tube oscillates 180° along both sides of the vertical, totaling about 360°. Each swing (2 × 360°) about 12s.

Test pressure: 400kPa

Test time: The sample rotates 90° after 5 minutes of test

Note: The spray pipe has 121 holes with a diameter of 0。5mm;

-- One hole in the center

-- Core area 2 floors (12 holes per floor, 30 degree distribution)

-- 4 outer rings (24 holes per ring, 15 degrees distribution);

-- Removable cover.

The spray pipe is made of copper-zinc alloy (brass).
