This work item implements the extension of the scope of the EN to cover Over the air (OTA) antenna performance requirements in terms of Receiver Total Radiated Sensitivity (TRS) and Total Radiated Power (TRP) for devices over 72mm wide, and will consider essential changes applicable to 3GPP release 13.

The present document contains the common requirements for marine radio communications and radio determination equipment and associated ancillary equipment operating from any combination of internal batteries, DC and single phase AC, in respect of ElectroMagnetic Compatibility (EMC). The provisions of the present document apply to marine radio equipment not covered in the scope of the Council Directive on marine equipment (the "Marine Equipment Directive" 2014/90/EU [i.4]). Product dependent arrangements necessary to perform the EMC tests on dedicated types of marine radio communications and radio determination equipment, and the assessment of test results, are detailed in the appropriate product related parts of the present document. The present document, together with the product related part, specifies the applicable EMC tests, the methods of measurement, the limits and the performance criteria for marine radio equipment and associated ancillary equipment. In case of differences (for instance concerning special conditions, definitions, abbreviation) between the present document and the relevant product related part of the present document, the product related part takes precedence. For the further content of the present document, the expression "radio equipment" is taken to mean marine radio communications or radio determination equipment, in each individual case. Technical specifications related to the antenna port of radio equipment and emissions from the enclosure port of radio equipment and combinations of radio and associated ancillary equipment are not included in the present document. Such technical specifications are normally found in the relevant product standards for the effective use of the radio spectrum. The environment classification used in the present document is maritime, as defined in EN IEC 60945 [i.3]. Marine radio communications equipment meeting the EMC requirements set out in EN IEC 61000-6-3 [i.1] and EN 61000-6-1 [i.2] is deemed to meet also the EMC requirements for the maritime environment described in EN IEC 60945 [i.3]. The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus intended to be used in the maritime environment. The levels, however, do not cover extreme cases which may occur in any location but with low probability of occurrence.

The present document covers the assessment of VHF radiotelephone transmitters and receivers for the maritime mobile service operating in the frequency range 156 MHz to 174 MHz, and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC) intended to be used in a marine environment. Technical specifications related to the antenna port and emissions from the enclosure port of marine radiotelephone transmitters and receivers are not included in the present document. Such technical specifications are found in the related product standards for the effective use of the radio spectrum. The present document specifies the applicable test conditions, performance assessment, and performance criteria for VHF radiotelephone transmitters and receivers for the maritime mobile service, and associated ancillary equipment. NOTE: The relationship between the present document and essential requirements of article 3.1b of Directive 2014/53/EU [i.2] is given in annex A.

The present document covers the assessment of the following maritime radio beacons in respect of ElectroMagnetic Compatibility (EMC): • Emergency Position Indicating Radio Beacons (EPIRBs) operating in the COSPAS-SARSAT satellite system in the UHF band 406,0 MHz to 406,1 MHz and in the maritime VHF band on frequencies 161,975 MHz (AIS1) and 162,025 MHz (AIS2). • Personal Locating Beacons (PLBs) operating in the COSPAS-SARSAT satellite system in the UHF band 406,0 MHz to 406,1 MHz. • Maritime Survivor Locating Devices (MSLDs) operating in the maritime VHF band on frequencies 156,525 MHz (CH 70), 161,975 MHz (AIS1) and 162,025 MHz (AIS2). • Mobile Aids to Navigation (AtoN) operating on 161,975 MHz (AIS1) and 162,025 MHz (AIS2). • Search And Rescue Transmitters (SARTs) operating on 161,975 MHz (AIS1) and 162,025 MHz (AIS2). Any of the above devices may also include homing transmitters operating on 121,5 MHz and/or 243 MHz. These devices may operate stand alone or together with ancillary equipment as a system. Technical specifications related to the antenna port and emissions from the enclosure port of radio beacons are not included in the present document. Such technical specifications are found in the related product standards for the effective use of the radio spectrum. The present document specifies the applicable test conditions, performance assessment, and performance criteria for radio beacons and the associated ancillary equipment. NOTE: The relationship between the present document and essential requirements of article 3.1b of Directive 2014/53/EU [i.2] is given in annex A.
