Waterproof They are all relatively meaningless because put anything in water for long enough and at high enough pressure and water will get in. Even if a radio is not submerged in water it can be damaged by water ingress from condensation which will find its way into electrical equipment that is fairly well sealed.

found here: http://www.protectingpeople.co.uk/fire_tech/ip_explained.htm IPx5 involves subjecting a transceiver to a shower of rain for three minutes from all directions. The water is delivered through holes of 6.3mm diameter at a rate of 12.5 l/minute and from a distance of 2.5m. This equates to water hitting the transceiver at a speed of 24km/hour - sufficient for it to be pushed away were it not anchored.
Electronic circuitry is fatally corroded even when slightly damp, particularly while powered. Should the worst happen and the radio does get wet, remove the battery at once. Keep the radio in a warm and airy place for a couple of days before putting the battery back. If salt water gets on or into the radio nothing will save it. Radios taken onto boats should always be protected by a totally waterproof and floating package. |
