The work
25、 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-governmen
26、tal, 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
27、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 Interna
28、tional 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 a
29、nd 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.

30、e technology Marine echo-sounding equipment 1Scope 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(V
31、II). 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 reliab
32、le 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
33、(17) is printed in italics. NOTEResolution A.224(VII) represents Resolution A.224(VII) as amended by Resolution MSC.74(69), annex 4. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.
34、 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.
35、 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.
