Ingress Protection (IP) Code Testing

ISO 17025

Ingress protection is the degree of protection provided by the product enclosure. In many cases, the level of protection provided by the enclosure is marked on the product in the form of an "IP" code. For example, IP 55 would indicate a dust protected (first digit 5) piece of equipment which is protected against water jets (second digit 5).

IP Code Chart

1st Digit	Protection Against Foreign Objects	2nd Digit	Protection Against Moisture
0	Not protected	0	Not protected
1	Protected against objects > 50 mm	1	Protected against dripping water
2	Protected against objects > 12 mm	2	Protected against dripping water tilted 15° N
3	Protected against objects > 2.5 mm	3	Protected against spraying water
4	Protected against objects > 1.0 mm	4	Protected against splashing water
5	Dust protected	5	Protected against water jets
6	Dust tight	6	Protected against heavy seas
7	Not applicable	7	Protected against the effects of immersion
8	Not applicable	8	Protected against submersion
