IP Code Designations

IP67 Coolant Proof Caliper

IP code (Ingress Protection Rating or International Protection Marking) classifies protection degrees of enclosures around electronic equipment against various environmental conditions (eg.: dust, fluids). These ratings are determined by specific tests

IP code consists of two numbers. The first number specifies protection against solid objects and the second protection against liquids. The higher the number, the better the protection.

 

First number - Protection against solid objects

0 No protection (Sometimes X)
1 Protected against solid objects up to 50mm?
2 Protected against solid objects up to 12mm?
3 Protected against solid objects up to 2.5mm?
4 Protected against solid objects up to 1mm?
5 Protected against dust, limited ingress (no harmful deposit)
6 Totally protected against dust

 

Second number - Protection against liquids

0 No protection (Sometimes X)
1 Protection against vertically falling drops of water (e.g. condensation)
2 Protection against direct sprays of water up to 15 degrees from vertical
3 Protection against direct sprays of water up to 60 degrees from vertical
4 Protection against water sprayed from all directions - limited ingress permitted
5 rotected against low pressure jets of water from all directions - limited ingress permitted
6 Protected against low pressure jets of water, limited ingress permitted (e.g. ship deck)
7 Protected against the effect of immersion between 15cm and 1m
8 Protected against long periods of immersion under pressure
