Ingress Protection (IP) testing
IP testing at TRaC's UKAS accredited test laboratory can determine a products susceptibility to solid particle (including dust) ingress and liquid (water) ingress.
The standard we most commonly use at TRaC for ingress protection is BS EN 60529. Within this standard it outlines an international classification system to test the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of solid particles and liquid. This classification system utilises the letters "IP" ("Ingress Protection") normally followed by two digits. The first digit of the IP rating represents the level of protection from solid ingress, and the second digit represents the level of protection from liquid ingress according the table below:
| IP rating | Level of protection | |
|---|---|---|
| Solid ingress |
IP1X | Protected against solid objects greater than 50mm diameter |
|
IP2X |
Protected against solid objects greater than 12.5mm diameter |
|
| IP3X |
Protected against solid objects greater than 2.5mm diameter |
|
| IP4X |
Protected against solid objects greater than 1.0mm diameter | |
| IP5X | Dust protected | |
| IP6X | Dust tight (with a vacuum applied to the product) | |
| Liquid ingress | IPX1 |
Protected against dripping water |
| IPX2 |
