IP CODES

IP codes signify the extent to which a product is protected against water or solid objects or dust getting through the exterior of the product and affecting its performance. IP stands for International Protection.

The IP codes are defined in IEC standard IEC 60529, which is identical to EN 60529 and BS EN 60529. The code is usually given in the form IP45. The first digit gives the protection provided against solid objects or dust and the second digit gives the protection against water. There are six levels of protection against penetration by solid objects or dust and eight levels of protection against ingress by water. For each level of protection a test is specified.

The tables show the protection offered at each level.

First Numeral Protection against ingress of solid foreign objects. IP Requirements Example 0 no protection 1 full penetration of 50mm diameter sphere not allowed and shall have adequate clearance from hazardous parts. Contact with hazardous parts not permitted. 2 full penetration of 12.5mm diameter sphere not allowed. The jointed finger shall have adequate clearance from hazardous parts. 3 the access probe of 2.5mm diameter shall not penetrate. 4 the access probe of 1.0mm diameter shall not penetrate. 5 limited ingress of dust permitted (no harmful deposit). 6 totally protected against ingress of dust.

Second Numeral Protection against harmful ingress of water IP Requirements Example 0 no protection 1 protected against vertically falling drops of water. Limited ingress permitted. 2 protected against vertically falling drops of water with enclosure tilted 15º from the vertical. Limited ingress permitted. 3 protected against sprays to 60º from the vertical - limited ingress permitted. 4 protected against water splashed from all directions - limited ingress permitted. 5 protected against low pressure jets of water from all directions - limited ingress permitted. 6 protected against strong jets of water. 7 protected against the effects of immersion between 15cm and 1m. 8 protected against longer periods of immersion under pressure.
