So, you might have seen IP ratings many times when checking out the specifications of any device, smartphone, or gadget. Even we here at Gadgets in Nepal mention IP ratings in almost all of our articles and Youtube Videos. Have you ever wondered, how IP rating works, who rates the device and provide them IP rating, and what numbers in IP rating mean? Today in this article we will be addressing all of these questions so without any further delay let’s get started. 

What is IP Rating? 

The IP rating stands for Ingress Protection Rating. In simple terms, IP rating is a measure of protection for your device from Solid and Liquid. The IP ratings are defined or developed by IEC. Under this, a device is tested under certain conditions and the ability of the device to hold on to those conditions defines its IP rating. 

How does IP rating Work?

An IP rating consists of two numbers determining its rating against Solid and liquid. The first digit in an IP rating can be from 0 to 6 and it defines the protection against solids increases from low to high. While the second digit determines the protection against liquids. For example, if a device is rated IP53, this means the device is dust resistant and can withstand water sprays that are sprayed at an angle of 60° from the vertical on either side of the device. Let’s look at the chart below to further understand IP ratings.
