EVS-EN 301 843-8 V1.1.1:2026

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 is given in annex A.
