13、m. Foreword The text of document 80/479/FDIS, future edition 2 of IEC 61097-1, prepared by IEC TC 80, Maritime navigation and radiocommunication equipment and systems, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61097-1 on 2007-08-01. This European Standard super
14、sedes EN 61097-1:1993. The main changes with respect to EN 61097-1:1993 are listed below: some amendments to bring the standard up to date with newer IMO resolutions and ITU recommendations. In particular, in 1995, the IMO adopted new performance standards for the SART in resolution A.802 (19) which
15、 replaced those of resolution A.697 (17). This new resolution introduced a new requirement for the SART to be provided with a pole arrangement. In 2006, the ITU-R revised recommendation M.628 to permit the optional use of circular polarisation with the SART; the Introduction has been deleted as it w
16、as of historical interest only; Annex A, which contained details of the parts of the EN 61097 series of standards, has been deleted; Annex B, which contained a Bibliography, has been deleted and the information moved into the normative references. The following dates were fixed: latest date by which
17、 the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2008-05-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2010-08-01 Annex ZA has been added by CENELEC. _ Endorsement notice The t

25、equirements, methods of testing and required test results 1 Scope This part of IEC 61097 specifies the performance standards and type testing of marine radar transponders used in search and rescue operations at sea (SART), as required by Regulation 6.2.2 of Chapter III, and 7.1.3 and 8.3.1 of Chapte
26、r IV of the 1988 amendments to the 1974 International Convention for Safety of Life at Sea (SOLAS), and which is associated with IEC 60936 (Shipborne radar) and IEC 60945 (General requirements). This standard incorporates the performance standards of IMO Resolutions A.530 (13) and A.802 (19) (Surviv
27、al craft radar transponders for use in search and rescue operations) and the technical characteristics for such transponders contained in ITU-R Recommendation M.628-4, and takes account of the general requirements contained in IMO Resolution A.694 (17). NOTE 1 The categories of SART operation which
28、are applicable to the stated SOLAS Regulations, IMO Resolutions and ITU-R Recommendation are: a) integral with a survival craft; b) portable and capable of floating; c) as part of an EPIRB. NOTE 2 This standard does not include non-SOLAS options for instance those envisaged in ITU-R Recommendation 6
29、28-4 - Considering (b). All text whose meaning is identical to that in IMO Resolutions A.530 (13), A.694 (17), A.802 (19) and ITU-R Recommendation M.628-4 is printed in italics. 2 Normative references The following referenced documents are indispensable for the application of this document.
