The present document specifies the minimum requirements for shipborne radio transmitters and receivers for fixed
installations operating in the VHF frequency bands between 156 MHz and 174 MHz used by the maritime mobile
service, using both 25 kHz and 12,5 kHz channels and capable of Radiotelephony and Digital Selective Calling
communications within the Global Maritime Distress and Safety System. The present document incorporates the
requirements of the relevant resolutions of the International Maritime Organization (IMO) and is primarily intended to
specify equipment suitable for fitting to ships subject to the SOLAS Convention [i.2] and complying with the Council
Directive 2014/90/EU [i.3] of 23 July 2014 on marine equipment (the European Marine Equipment Directive).
The present document does not address the testing of ancillary equipment on a stand-alone basis, i.e. separately from the
radio equipment with which it is to be used.
