IP Level Test Introduction

IP Level Test Introduction

 

IP is the abbreviation of Ingress Protection. IP grade is the protection level for electrical equipment shell against the foreign body intrusion. It comes from the international electrical commission standard IEC 60529 which was also used as the national standard of America in 2004. In this standard, for the protection level of electrical equipment shell against the foreign body intrusion, the IP level format is IPXX. In which the XX are the two Arabia number. The first tag number indicates the protection level of contact protection and external object protection; the second tag number indicates the protection level of waterproof. For the more specific protection level can refer to the table below.

Level of protection usually uses IP with the following two figures to express. The numbers used to specify the protection level. The first number indicates the range of the device against dust, or the extent of people against damage in sealed environment. ‘ I ‘ represents the level of prevention of the entry of solid foreign bodies, and the highest level is 6; the second number indicates the level of the device against water. P representative the level prevent from water, the highest level is 8. Such as the protection level of motor IP65, IP55 and so on.

Dustproof Level

 

Number Protection Level Definition
0 No protection No special protection
1 Prevent objects from more than 50mm Prevent the human body from accidentally touch the internal parts of the lamp, prevent the object intrusion which diameter is greater than 50mm
2 Prevent objects from more than 12mm Prevent the finger from the internal parts of the lamp
3 Prevent objects from more than 2.5mm Prevent the object, tool, wire intrusion which diameter is greater than 2.5mm
4 Prevent objects from more than 1.0mm Prevent the mosquitoes, insects or objects intrusion which diameter of more than 1.0mm
5 Dustproof Can not completely prevent dust intrusion, but the amount of intrusion of dust will not affect the normal operation of electrical
6 Dustproof Completely prevent dust intrusion

Waterproof Level

 

Number Protection Level Definition
0 No protection No special protection
1 Prevent water dripping Prevent vertical drop of water
2 Prevent dripping water intrusion even when inclined 15 degrees Can still prevent dripping when the lamp is inclined 15 degrees,
3 Prevent the injection of water intrusion Prevent rain, or vertical to the angle is less than 50 degrees in the direction of the water jet
4 Prevent splashing water intrusion Prevent water from splashing in all directions
5 Prevent the ingress of water waves Prevent the waves or spray holes rapidly sprayed water from intrusion
6 Prevent the ingress of water waves Lamps and lanterns can still ensure the normal operation when into the water in a certain time or water pressure conditions,
7 Prevent water from immersing into the lamp The lamp has no time limit for the submerged water under the condition of a certain water pressure, and can ensure the normal operation
8 Prevent the sinking Prevent the sinking

 

(1) IPX 1

Method name: Vertical drop test

Test equipment: Drop test device

Sample placement: According to the normal working position of the sample, place the sample on the rotating sample table of 1r/min. The distance between the top of the sample and the drop mouth is no more than 200mm

Test condition: Drip rate is 10.05 mm/min

Duration: 10 min

(2) IPX 2

Method name: Inclined 15 degree drop test

Test equipment: Drop test device

Sample placement: Making a 15° angle between the sample surface and the vertical line. The distance between sample top to drip mouth no greater than 200mm. After each test, change to the other side, a total of four times.

Test condition: Drip volume is 30.5 mm/min

Duration: 4 x 2.5 min (total 10 min)

(3) IPX 3

Method name: water spray test

Test method:

  1. Swing Tube type spray test

Test equipment: Swing pipe type water splashing test device

Sample placement: Select the appropriate radius of the tube so that the sample table height is in the position of the diameter of the pipe diameter. Place the sample on the sample table to make the distance between the top of the sample is no more than 200mm, and the sample table is not rotated.
Experimental conditions: Water volume calculated according to the number of holes in the pipe, each hole is 0.07 L/min. When pouring water, the spray hole which placed in the both sides of the swing pipe would spray to the sample. The sample placed in the pipe center circle. The swing pipe would swing 60° twice on both sides of the vertical of 60 degrees, total 120°. Each swing (2 x 120) is about 4s

Test time: Continuous pouring water 10 min

  1. Shower nozzle type shower water test

Test equipment: Portable water splashing test device

Sample placement: Make the parallel distance between the top of the test and the head of the hand-held nozzle is 300mm to 500mm

Test condition: When the test should be installed with the balance of the baffle, the water flow is 10 L/min

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

(4) IPX 4
