Radio Equipment and Systems (RES); ElectroMagnetic Compatibility (EMC) for Radiotelephone Transmitters and Receivers for the Maritime Mobile Service Operating in the VHF Bands
The European Telecommunication Standard (ETS) covers the assessment of radiocommunication and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions for the enclosure port of the radio equipment are found in the related product standard ETS 300 162 [7] for the effective use of the radio spectrum. This ETS specifies the applicable EMC tests@ the test methods@ the limits and the minimum performance criteria for transmitters and receivers for fixed installation on board ships operating in the maritime VHF bands in the frequency range 156 MHz - 174 MHz@ and the associated ancillary equipment. The electromagnetic environment used in thus ETS to develop the technical specifications encompasses the electromagnetic environment on board ships as identified in EN 60945 [8]. The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus in maritime environments. The levels do not cover extreme cases which may occur in any location but have a low probability of occurrence. Compliance of radio equipment to the requirements of this ETSdoes not signify compliance to any requirements related to the use of the equipment (i.e. licensing requirements). Compliance to the ETS does not signify compliance to any safety requirements. However@ it is the responsibility of the assessor of the equipment that any observations regarding apparatus becoming dangerous or unsafe as a result of the application of the tests defined inthis ETS@ shall be recorded in the test report. This ETS is based on the considerations and guidance as given in ETR 238 [9].
