IP Rating

An IP rating, also known as "International Protection" or "Ingress Protection" rating, is a value assigned to a product that determines its susceptibility to ingress from solids and liquids. The first numeric digit relates to the level of protection against solid objects, and the second numeric digit indicates the level of protection against liquid ingress.
