Ingress Protection (IP) Ratings
What does IP stand for?
IP is an acronym for Ingress Protection
Why is Ingress Protection Important?
Liquid and/or solid particle ingress into electrical equipment may not only be harmful to the equipment, it may also be dangerous to the operator. Therefore when buying electrical equipment whether it be a transmitter, a switch, or a warning beacon it is essential to know what degree of ingress protection the item offers.
So how is Ingress Protection quoted?
An "IP" number, or as it is commonly known, an IP rating is used to specify the environmental protection offered. The IP rating is composed of two numbers, the first referring to the protection against solid object ingress and the second against liquid ingress. The higher the number the better the protection.
Are there standards covering these ratings?
The applicable European standards for ingress protection are:
- BS EN 60529 Specification of Degrees of Protection Provided by Enclosures
- IEC 529 Specification of Degrees of Protection Provided by Enclosures.
