IP Ratings Explained
What is an IP Rating?
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. (As defined in international standard IEC 60529.) The standard aims to provide users more detailed information than vague marketing terms such as “waterproof”.
The digits (numerical characteristics) indicate conformity with the conditions summarised 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.
First Digit: Solids
The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g. electrical conductors, moving parts) and the ingress of solid foreign objects.
Second Digit: Liquids
Protection of the equipment inside the enclosure against harmful ingress of water.
