Ingress Protection (IP) Ratings Explained

What is an IP Rating?

Ingress Protection Rating (IP Rating) is an international standard, IEC 60529, for classifying the degree of protection provided by mechanical casings and electronic enclosures.

What do the Numbers Mean?

An IP rating is shown as two numbers. The first number defines the protection rating against solid objects, including people and tools. The second number shows the protection offered against liquids.
The table below shows the levels of protection offered by each:
