What does IP67 mean?
IP67 is two numbers, one that refers to the dust resistance rating and one that refers to water resistance.
IP6x is the highest dust resistance rating, so this product is fully protected against dust.
IPx7, the water resistance rating, means this product can withstand immersion in water up to one meter (3.3 feet) for 30 minutes, tested in laboratory conditions.
IPx7 is the second-highest rating, below IPx8, which indicates an ability to withstand long periods of submersion under pressure.
First digit: Solid particle protection
The first number in the rating code represents the degree of protection provided against the entry of foreign solid objects, such as fingers or dust. These protection levels range from 0 to 6.
| Code | Effective against | Description |
|---|---|---|
| 0 | - | No protection against contact and ingress of objects |
| 1 | >50 mm | Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part |
| 2 | >12.5 mm | Fingers or similar objects |
| 3 | >2.5 mm | Tools, thick wires, etc. |
| 4 | >1 mm | Most wires, slender screws, large ants etc. |
| 5 | Dust protected | Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment. |
| 6 | Dust tight | No ingress of dust; complete protection against contact (dust tight). A vacuum must be applied. Test duration of up to 8 hours based on air flow. |
Second digit: Liquid ingress protection
The second number represents the degree of protection against the entry of moisture, with protection levels ranging from 0 through 8.
| Code | Protection against | Test duration | Description |
|---|---|---|---|
| 0 | - | - | No protection |
| 1 | Dripping water | 10 mins | Protection against vertically dripping water |
| 2 | Dripping water when tilted at 15° | 10 mins | Protection against vertically dripping water when device is tilted at an angle up to 15 degrees |
| 3 | Spraying water | 5 mins | Protection against direct sprays of water when device is tilted at an angle up to 60 degrees |
| 4 | Splashing of water | 5 mins | Protection from sprays and splashing of water in all directions. |
| 5 | Water jets | 3 mins from a distance of 3 meters | Protection from low-pressure water projected from a nozzle with a 6.3mm diameter opening in any direction | 6 | Powerful water jets | 3 mins from a distance of 3 meters | Protection from water projected in powerful jets from a nozzle with a 12.5mm diameter opening in any direction |
| 7 | Immersion, up to 1 m depth | 30 mins | Protected from immersion in water with a depth of up to 1 meter (or 3.3 feet) for up to 30 mins | 8 | Immersion, 1 m or more depth | Varies | Protected from immersion in water with a depth of more than 1 meter (manufacturer must specify exact depth) |
