Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 9875 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 6, Navigation. This third edition cancels and replaces the second edition (ISO 9875:1996), which has been technically revised. Annex A forms a normative part of ISO 9875. Annex B is for information only. iv ISO 2000 All rights reserved
INTERNATIONAL STANDARD ISO 9875:2000(E) Ships and marine technology Marine echo-sounding equipment 1 Scope This International Standard specifies the minimum operational and performance requirements, methods of testing and test results of marine echo-sounding equipment required to comply with the performance standards adopted by the IMO Resolution A.224(VII). In addition, it takes account of IMO Resolution A.694(17) and is associated with IEC 60945. When a requirement in this International Standard is different from IEC 60945, the requirement in this International Standard takes precedence. The purpose of echo-sounding equipment is to provide reliable information on the depth of water under a ship to aid navigation in particular in shallow water. This International Standard is applicable for ship speeds from 0 kn to 30 kn. Any text in this International Standard with wording identical to that in the IMO Resolution A.224(VII) and IMO Res. A.694(17) is printed in italics. NOTE Resolution A.224(VII) represents Resolution A.224(VII) as amended by Resolution MSC.74(69), annex 4. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. IEC 60945:1996, Maritime navigation and radiocommunication equipment and systems General requirements, methods of testing and required test results. IEC 61162, Maritime navigation and radiocommunication equipment and systems Digital interfaces. IMO Resolution A.224(VII), Performance standards for echo-sounding equipment. IMO Resolution A.694(17), General requirements for shipborne radio equipment forming part of the global maritime distress and safety system (GMDSS) and for electronic navigational aids. International Convention of Safety of Life at Sea (SOLAS) Chapter V, Regulation 12, Shipborne navigational equipment. 3 Terms and definitions For the purposes of this International Standard, the following terms and definitions apply.
