IP Rating Chart

Ingress Protection (IP) Rating
IP Number First Digit - Protection from Solids IP Number Second Digit - Protection from Liquids
0 Not protected from solids. 0 Not protected from liquids.
1 Protected against solid objects over 50 mm, e.g. accidental touch by persons hands. 1 Protection against vertically falling drops of water e.g. condensation.
2 Protected against solid objects over 12 mm, e.g. persons fingers. 2 Protection against direct sprays of water up to 15° from the vertical.
3 Protected against solid objects over 2.5 mm (tools and wires). 3 Protected against direct sprays of water up to 60° from the vertical.
4 Protected against solid objects over 1 mm (tools, wires, and small wires). 4 Protection against water sprayed from all directions - limited ingress permitted.
5 Protected against dust limited ingress (no harmful deposit). 5 Protected against low pressure jets of water from all directions - limited ingress.
6 Totally protected against dust ingress. 6 Protected against temporary flooding of water, e.g. for use on ship decks - limited ingress permitted.
7 – 7 Protected against the effect of immersion between 15 cm and 1 M.
8 – 8 Protects against long periods of immersion under pressure.
9k – 9k Protected against close range high pressure, high temperature water jet.
