Mobile WebSiteIP (INGRESS PROTECTION) The protection system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION) to classify electrical appliances according to their dust and moisture resistance characteristics. IP protection level is composed of two figures, the first number that electrical dust, to prevent the intrusion of foreign objects, the second number that electrical anti-moisture, waterproof intrusion of the degree of closure, the greater the number that the degree of protection high. With the continuous improvement of product quality, protection requirements are getting higher and higher.
| Dust rating | waterproof level | ||||
| digital | Protection range | Description | digital | Protection range | Description |
| 0 | No protection | No special protection for people or things outside | 0 | No protection | No special protection against water or moisture |
| 1 | To prevent the diameter of more than 50mm of foreign objects intrusion | To prevent the body (such as the palm of your hand) due to accidental access to electrical parts inside, to prevent larger size (diameter greater than 50mm) of foreign objects intrusion | 1 | Prevent water immersion | Vertical drops of water droplets (such as condensate) will not cause damage to electrical appliances |
| 2 | To prevent the diameter of more than 12.5mm of foreign objects intrusion | Prevents human fingers from touching parts inside the appliance and prevents foreign objects from medium size (diameter greater than 12.5mm) | 2 | Tilt 15 degrees, can still prevent water immersion | When the electrical tilt from the vertical to 15 degrees, the water will not cause damage to the electrical |
| 3 | To prevent the diameter of more than 2.5mm of foreign objects intrusion | To prevent the diameter or thickness of more than 2.5mm tools, wires and similar small foreign objects invade and access to electrical parts | 3 | Prevent water from spraying | Rain or prevent damage from the water sprayed into the appliance in a direction with a vertical angle of less than 60 degrees |
| 4 | To prevent the diameter of more than 1.0mm solid foreign objects intrusion | To prevent the diameter or thickness of more than 1.0mm tools, wires and similar small foreign objects into contact with the electrical parts of the internal | 4 | Prevent splash of water from dipping | To prevent all aspects of the splash of water into the electrical damage caused |
| 5 | To prevent foreign objects and dust | Completely prevent foreign invasion, although not completely prevent the intrusion of dust, but the amount of dust intrusion will not affect the normal operation of electrical appliances | 5 | To prevent the water from being sprayed | To prevent the water from the nozzle from all directions into the electrical damage caused by the nozzle |
| 6 | To prevent foreign objects and dust | Completely prevent foreign objects and dust intrusion | 6 | To prevent the big waves immersed | Installed on the deck of the electrical appliances, to prevent damage caused by the invasion of the waves |
| 7 | To prevent immersion in water when immersed | Electrical equipment immersed in water for a certain period of time or water pressure below a certain standard to ensure that damage is not caused by flooding | |||
| 8 | To prevent submerged water immersion | Can be completely immersed in the water structure, the experimental conditions determined by the producers and users | |||
