IP ratings

IP Ratings Explained

An Ingress Protection (IP) rating is an international rating which tells people how well electrical devices, such as two-way radios, are protected from solids and liquids. So, if you’re thinking of buying two-way radios, IP ratings should definitely be considered. Of course, this all depends on your reason for using two-way radios and the industry you’re working in. For example, some industries may need protection for any accidental wear and tear, yet construction industries would need two-way radios that are extremely resilient against dust and water.

The first number I an IP rating explains how well the device resists foreign materials entering it:

  • 0 = No special protection
  • 1 = Protected against objects greater than 50mm in diameter
  • 2 = Protected against objects greater than 12.5mm in diameter
  • 3 = Protected against objects greater than 2.5mm in diameter (tools/thick wires)
  • 4 = Protected against objects larger than 1mm (wires/screws or large ants)
  • 5 = Dust protected – not entirely prevented but cannot enter in sufficient quantity to interfere with the operation of the equipment
  • 6 = Complete protection (dust tight)

The second number of an IP rating indicates its resistance to liquids (freshwater only)

  • 0 = None
  • 1 = Protected against dripping water (vertically falling drops)
  • 2 = Protected against dripping water (when tilted at 15 degrees)
  • 3 = Protected against spraying water (at any angle up to 60 degrees)
  • 4 = Protected against splashing water
  • 5 = Protected against low pressure water jets
  • 6 = Protected against powerful water jets and waves
  • 7 = Protected against temporary immersion (up to 1 metre in depth) for up to 30 minutes
  • 8 = Protected against prolonged immersion under pressure (beyond 1 metre)
