STRUCTURE, MEANING OF IP54
The structure of the IP protection level IP54 examples include: IP and two digits. The first digit (5) speaks of protection against dust penetration, 2nd digit (4) speaks of protection against water penetration.
MEANING OF THE FIRST: LEVEL AGAINST DUST
1 Said to prevent the intrusion of solid objects larger than 50mm. Protection from objects (such as hands) touch lamp parts at random. Prevent material size (diameter) greater than 50mm.
2 Indicates that prevents the entry of objects with larger average size of 12mm. Prevent the entry of fingers and other objects with average size (diameter greater than 12mm, length greater than 80mm).
3 Said to prevent the intrusion of solid objects larger than 2.5mm. Prevent objects (eg tools, wires or similar) with a diameter or thickness greater than 2.5mm to touch the inner parts of the lamp.
4 Said to prevent the intrusion of solid objects larger than 1.0mm. Prevent the objects (tools, wires or similar) with a diameter or thickness greater than 1.0mm to touch the inside of the lamp.
5 Indicate dust protection. Prevent the intrusion of solid objects completely, it can not prevent the intrusion of dust completely, but dust does not affect the normal operation of the device.
6 Indicates integral dust protection. Prevent the entry of objects and dust completely.
MEANING OF THE SECOND: WATER RESISTANCE LEVEL
0 Indicates no protection.
1 Only to prevent the penetration of water dripping. Vertical drops of water (such as rain, without wind) does not affect the operation of the device.
2 Only prevent the infiltration of water at 15 degrees angle. Or when the device is tilted 15 degrees, vertical dripping water will not cause any harm.
3 Indicates that prevents the penetration of small water jets, light. Equipment that can withstand water jets, water hose in a smaller angle of 60 degrees (Specifically as rain accompanied by strong winds)
4 Said to prevent the intrusion of water from the nozzle in all directions.
5 Said to prevent the intrusion of high pressure water jets in all directions.
6 Said can resist the intrusion of big waves. Equipment can be mounted on the deck, and can withstand big waves.
7 Said device can be soaked in water for 1 short time in little water pressure.
8 Said device can operate normally while domestic long soak in water pressure one certain, and ensure that no harm caused by water.
