Solid Objects and Liquids

The IP Protection Index

The IP Protection index is used internationally to classify a products level of protection against intrusions by solids e.g. dirt / dust and liquids e.g. oil / water.

How to read the (IP) protection index rating
Example: Petzl Pixa 3 - IP67
The first number indicates the products protection against solids, the second liquids. By reading the table below you can see that the Petzl Pixa 3 is a completely dust proof product able to withstand immersion in water for upto 30 min at a maximum depth of 1m.

Note: If a product has only been tested against one of the criteria the missing figure will be replace by an 'X'. For example IP6X means a product is completely dust proof but has not been tested against water ingress.

The first number relates to protection against solid objects:
X: Not measured -
0: Not protected -
1 = Protected against solids ≥ 50 mm in diameter IP table image 1
2 = Protected against solids ≥ 12.5 mm in diameter IP table image 2
3 = Protected against solids ≥ 2.5 mm in diameter IP table image 3
4 = Protected against solids ≥ 1mm in diameter IP table image 4
5 = Protected against dust (limited ingress, no harmful deposits) IP table image 5
6 = Completely protected against dust IP table image 6
The second number indicates protection against liquids:
X: Not measured -
0: Not protected -
1 = Protected against vertically falling water drops
2 = Protected against water drops (15° from vertical) IP table image 7
3 = Protected against rain (60° from vertical) IP table image 8
4 = Protected against sprayed water IP table image 9
5 = Protected against jets of water IP table image 11
6 = Protected against forceful hose-projected water IP table image 12
6 = Temporary immersion (-1 meter for 30 minutes) IP table image 13
6 = Prolonged immersion (deeper than 1 meter for period defined by manufacturer) IP table image 14

Electromagnetic compatibility (EMC)

Electromagnetic compatibility (EMC) describes the ability of an electric device to work properly, independent of possible electromagnetic disturbances in the environment, and without producing its own. All Petzl headlamps conform to the requirements of the 89/366/CEE directive concerning electromagnetic compatibility: they will not interfere with any other CE-marked devices.
