The IP rating is the protection level provided by enclosures to electrical equipment. This is denominated by a two digit number; for example IP67 is;
- 6 = product is completely protected from dust
- 7 = product is completely protected against the effect of immersion
Please see below table for explanation of all digits.
Protected against solid bodies larger than 50mm (eg. accidental contact with the hand)
Protected against vertically falling drops of water (condensation)
Protected against solid bodies larger than 12mm (eg. finger of the hand)
Protected against drops of water falling at up to 15 degrees from the vertical
Protected against solid bodies larger than 2.5mm (eg. tools and wires)
Protected against drops of rain water at up to 60 degrees from the vertical
Protected against the solid bodies larger than 1mm (fine tools and small wires)
Protected against splashings of water from all directions (360 degrees)
Protected against dust (no harmful deposit). Completed protection from solid bodies
Protected against jets of water from all directions (12.5mm bore nozzle, 10m head, 3m distance)
Completed protection against dust. Complete protection from solid bodies.
Protected against jets of water of similar force to heavy seas. Same conditions as 5 but distance of 1.5m
Protected against the effects of immersion at a specified pressure for a limited time (1m immersion).
Protected against the effects of immersion at a specified pressure for unlimited time(1m immersion).
