IP Testing (Ingress Protection Testing)

IP testing (Ingress Protection) is designed to certify a product's
resistance to the intrusion and or ingress by  foreign objects as defined
by BS EN 60529:1992. 
It certifies a product's resistance to intrusion by foreign objects and water and is signified by the IP testing coding IPXX. 

The meanings of the IP testing coding
for the first and second numeral indicating degree of protection is given in the tables below.

Sample diagrams of IP testing rigs are also given.
