The IP stands for Ingress Protection.
The Rating is the sealing level for electrical enclosures against intrusions from foreign bodies. In simple terms this basically means the devices protection level against solids and liquids.
The IP rating is made up of two numbers. The first number relates to the level of protection against solids and the second number relates to the level of protection against liquids.
The above image breaks down the defition of the IP ratings that you will see on two-way radio products.
The first number is rated on a scale of 0 to 6
0 being no protection against solid objects and 6 meaning effectively dust proof.
The second number is rated on a scale of 0 to 8
0 being no protection against liquids and 8 meaning protected against immersion greater than 1 metre.
It's important to note that the second number is the number which reflects whether a two-way radio is waterproof or not.
