The Definitive Guide to IP Ratings
Sep 25, 2020

What does “IP Rating” stand for and what does it mean?

IP Ratings is a short form for Ingress Protection (IP) mark, IEC standard 60529. This system was started by the International Electrotechnical Commission or short form IEC.

IP Ratings are normally comprised of two digits that is commonly used for electrical items such as current day mobile phones or mechanical enclosures such as explosion proof enclosures. This rating would be able to tell people immediately the level of protection that the product has based on the table further below.

What do the numbers in “IP Ratings” mean?

An IP rating is usually formed by 2 numbers. The 1st number would indicate the level of protection from solid objects or materials. The 2nd number indicates the level of protection from liquids such as water and the higher the number the better the protection. An example of an IP Rating could be “IP56” which would mean the item is dust resistant as well as protected against powerful jets of water.

Let us see what the various numbers mean below:
