Ip Classification Codes - Icom IC-F9511T User Manual

Ingress Protection (IP) ratings are developed by the European Committee for Electro Technical Standardization.
International Standard IEC 60529 outlines an international classification system that describes the sealing
characteristics of electrical equipment. The classification system defines the level of protection provided by
enclosures to prevent the ingress of foreign objects and moisture into the electrical equipment.
The classification system uses the "IP" code, or "Ingress Protection" code, to define the level of seal. An IP
number contains two numbers (i.e. IP57) in most instances which relate to the level of protection provided by an
enclosure or housing. Either number may be shown as "X" (i.e. IPX6 / IP7X) to indicate the "X" part is not tested.
