The protection level is IP57, the IP54 waterproof than the m65 stronger.
IP stands for Ingress Protection yes, IP rating of electrical equipment against foreign body penetrated the protective shell of the hierarchy, the source is the International Electrotechnical Commission standard IEC 60529, this standard was adopted in 2004 as the U.S. national standards.
In this standard for electrical equipment enclosure of the foreign body protection, IP level format IPXX, where XX is two digits, the first tag number, said access to the conservation and protection level of foreign objects, and the second tag numbers indicate water level of protection , the specific protection level can refer to the following form.
IP is an international code used to identify levels of protection levels Ip formed by the two figures, the first digit dust; second number from said water-proof, the greater the number of its defense chief, said the better.
Dust Level
Number of degree of protection Definition
0 No protection, no special protection
An object to prevent the intrusion of more than 50mm (large-size objects) to prevent exposure to light accidentally encounter the internal parts is greater than 50mm in diameter to prevent the intrusion of objects
2 is greater than 12mm to prevent the intrusion of the object (medium-size objects) to prevent the internal parts fingers encountered lamps
3 to prevent objects larger than 2.5mm of invasive (small-size objects) to prevent the tool diameter greater than 2.5mm, wire or object intrusion
4 to prevent objects larger than 1.0mm of the intrusion (granular object) diameter greater than 1.0 to prevent mosquito, insects or objects invasive
5 dust can not completely prevent dust intrusion, but the intrusion of dust will not affect the amount of the normal operation of equipment,
6 dust to completely prevent dust intrusion (sealed), improve the anti-contact protection.
Waterproof grade
Number of degree of protection Definition
0 No protection, no special protection
An invasion to prevent the vertical drop to prevent the dripping of water droplets
2 tilted 15 degrees to prevent dripping water intrusion when the lights are still tilted 15 degrees, can prevent the drip
3 to prevent the jet of water to prevent intrusion of rainwater, or vertical angle of less than 50 degrees into the direction of the water jet
4 to prevent the splash of water splashing from all directions to prevent the intrusion of water intrusion
5 to prevent the big wave of water intrusion to prevent the big wave, or blowhole spray of water intrusion rapid
6 to prevent the waves of water intrusion in water intrusion devices in a certain time or under conditions of pressure, can guarantee the normal operation of equipment,
7 to prevent the intrusion of water of water intrusion devices without sinking in the water in a certain period of water pressure conditions, can guarantee the normal operation of equipment,
8 to prevent the impact of sinking when the device continuously immersed in water, which soaked the conditions determined by the manufacturer, installation is still nice. Usually this means that the device is completely sealed, welded firmly to. However, certain types of equipment, water can still enter into the water just said does not harm the operation of the equipment only. |
