IP protection index and EMC

The IP protection index is an international standard. This index classifies the level of protection offered by equipment against intrusions by solids (e.g. dust) and liquids (e.g. water, oil).

Ultra-powerful headlamp.

How do you read the protection index?

Example: IP 67

  • The first number indicates protection against solid objects.
  • The second number indicates protection against liquids.

The IP 67 notation therefore corresponds to a completely dustproof product that is protected against the effects of immersion in liquid.

NB : When a criterion has not been tested, the number is replaced by X (e.g., IP X6 indicates that the product has not been tested for solids). The IP protection index is an international standard. This index classifies the level of protection offered by equipment against intrusions by solids (e.g. dust) and liquids (e.g. water, oil).

The first number indicates protection against solid objects

X = Not measured

-

0 = Not protected

-

1 = Protected against projection of solid objects 50 mm or greater in diameter 1 = Protected against projection of solid objects 50 mm or greater in diameter
2 = Protected against projection of solid objects 12.5 mm or greater in diameter 2 = Protected against projection of solid objects 12.5 mm or greater in diameter
3 = Protected against projection of solid objects 2.5 mm or greater in diameter 3 = Protected against projection of solid objects 2.5 mm or greater in diameter
4 = Protected against projection of solid objects 1 mm or greater in diameter 4 = Protected against projection of solid objects 1 mm or greater in diameter
5 = Protected against dust (limited ingress, no harmful deposits) 5 = Protected against dust (limited ingress, no harmful deposits)
6 = Completely protected against dust 6 = Completely protected against dust

The second number indicates protection against liquids

X = Not measured

-

0 = Not protected

-

1 = Protected against vertically falling water drops 1 = Protected against vertically falling water drops
2 = Protected against water drops (15° from vertical) 2 = Protected against water drops (15° from vertical)
3 = Protected against rain (60° from vertical) 3 = Protected against rain (60° from vertical)
4 = Protected against splashing water 4 = Protected against splashing water
5 = Protected against water jets 5 = Protected against water jets
6 = Protected against powerful water jets 6 = Protected against powerful water jets
7 = Temporary immersion (-1 meter for 30 minutes) 7 = Temporary immersion (-1 meter for 30 minutes)
8 = Prolonged immersion (deeper than 1 meter for period defined by manufacturer) 8 = Prolonged immersion (deeper than 1 meter for period defined by manufacturer)
