The present document has been produced by in response to a mandate from the European Commission issued under Council Directive 98/34/EC [6] (as amended) laying down a procedure for the provision of information in the field of technical standards and regulation. The present document, together with EN [1], is intended to become a Harmonized Standard, the reference of which will be published in the Official Journal of the European Communities referencing the Council Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility ("the EMC Directive") (89/336/EEC [3] as amended), and Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity (the "R&TTE Directive" [2]). The present document is part 2 of a multi-part deliverable. Full details of the entire series can be found in part 1 [1]. National transposition dates Date of adoption of this EN: 4 June 2004 Date of latest announcement of this EN (doa): 30 September 2004 Date of latest publication of new National Standard or endorsement of this EN (dop/e): 31 March 2005 Date of withdrawal of any conflicting National Standard (dow): 31 March 2006
5 5 EN V1.2.1 ( ) 1 Scope The present document together with EN [1], covers the assessment of VHF radiotelephone transmitters and receivers for the maritime mobile service, and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC). 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 the associated ancillary equipment. Examples of types of radiotelephone transmitters and receivers for the maritime mobile service covered by the present document are given in annex A. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and EN [1], the provisions of the present document take precedence. The electromagnetic environment used in the present document to develop the technical specifications encompasses the electromagnetic environment onboard ships as identified in EN [5]. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
