What does "IP Rating" mean?
IP Rating, outlined in International Standard IEC 60529, stands for International Protection Rating (or sometimes also interpreted as Ingress Protection Rating) and classifies the degrees of protection provided against the intrusion of both solid object and water in electrical enclosures. This rating aims to provide users with more detailed information than by vague
marketing terms such as "outdoor or water-proof". IP Rating consists of the letter IP followed by two digits and an optional letter. The digits indicate conformity with the conditions summarized in thereference table of IP Rating Code.
Example of an IP Rating Code
IP 6 6
A component with this IP code indicates that a component is protected against ingress of dust completely(first number 6); and is protected against harmful effects due to water powerfully jetted against the component from any direction (second Number 6).
