What do IP Specification for Water/Dust Resistance mean for Two Way Radios?

17 June 2016

There was a time when only marine radios were waterproof. Over time and with developments in radio technology, both commercial two way radio and Amateur radio equipment now benefit from this feature.

One of the questions we are commonly asked is what does IP stand for and importantly what does it mean for the product I have purchased?

There are different levels of waterproofing and dust protection. IP "Ingress Protection" ratings are measured from "0" to "8" to define the level of water ingress or from "0" to "6" to state the level of dust protection built into each radio. If the product was tested in compliance with this standard it is usually listed on our leaflets.

If something has a water only rating (whether 4, 5, or 6) you write it as IPX5. The X acts as a placeholder since there is not a particle (or dust rating). If something has a dust rating of 6 (dustproof) and a water rating of 5, you write it as IP65. In the rare instance that the dust and water rating are the same (let’s say 6), you write it as IP6.
