IP CODES
Degrees of Protection Provided by Enclosures (IP Codes)
Munawar Abbas (I.Dip NEBOSH – UK)
• The IP Code (or International Protection Rating, sometimes also
interpreted as Ingress Protection Rating*) consists of the letters IP
followed by two digits and an optional letter. As defined in
international standard IEC 60529, it classifies the degrees of protection
provided against the intrusion of solid objects (including body parts
like hands and fingers), dust, accidental contact, and water in electrical
enclosures. The standard aims to provide users more detailed
information than vague marketing terms such as waterproof.
• The digits (characteristic numerals) indicate conformity with the
conditions summarized in the tables below. For example, an electrical
socket rated IP22 is protected against insertion of fingers and will not
be damaged or become unsafe during a specified test in which it is
exposed to vertically or nearly vertically dripping water. IP22 or 2X are
typical minimum requirements for the design of electrical accessories
for indoor use.

certain types of equipment, it can mean that water can enter but only
in such a manner that it produces no harmful effects.
