IP rating consists of IP and two numbers, the two numbers represent solid particle protection and liquid ingress protection respectively. The first number “6” means dust-tight, and the second number “7” means ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 meter (3 ft 3 in) of submersion), then test duration is 30 minutes. It means that our IP67 products can be completely dust-tight and waterproof.
Solid particle protection
The first digit indicates the level of protection that the enclosure provides against access to internal components (such as electronic and mechanical parts) and the ability to defend against the entry of external objects.
| Level | Protects balls of the following diameters from completely entering the enclosure |
|---|---|
| 0 | — |
| 1 | >50mm |
| 2 | >12.5mm |
| 3 | >2.5mm |
| 4 | >1mm |
| 5 | Dust protected |
| 6 | Dust-tight |
Liquid-penetration protection
The second number indicates the ability of the device enclosure to resist liquid penetration.
| Level | Protection | Target |
|---|---|---|
| 0 | None | — |
| 1 | Dripping Water | Dripping water (vertically falling drops) shall not effect the safety |
| 2 | 15 degree tilt dripping | When tilted to 15° of normal posture, vertical water droplets should have no negative effects under umbrella protection |
| 3 | Spraying water | There should be no negative effects such as penetration of the pressurized spray above the outside of the equipment (within 60 degrees of the vertical line) |
| 4 | Splash | Water splashing on the device from any angle should have no negative effect |
| 5 | Water jets | The water jet from the nozzle (6.3mm) should be sprayed on the equipment casing from any angle without negative effects |
| 6 | High pressure water jets | The water jet from the nozzle (12.5 mm) should be sprayed on the equipment casing from any angle without negative effects |
| 7 | Immersion in water up to 1m(3 ft 3 in) | The device enclosure will not damage the device when immersed in water (up to 1m) under defined conditions, including water pressure and time |
| 8 | Immersion in water more than 1m(3 ft 3 in) | The equipment may be suitable for prolonged immersion in water under the conditions specified by the manufacturer. Usually this means that the device is sealed. However, on some devices, it can also mean that water can enter without causing negative effects |
| 9 | High pressure and high-temperature water jets | Equipment can withstand close-range high temperature and high pressure water jet impact under the conditions specified by the manufacturer |
