The work of preparing International
23、 Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also
24、 take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (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 b
25、y 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
26、ofpatent 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 987
27、5:1996), which has been technically revised.Annex A forms a normative part of ISO 9875. Annex B is for information only.EN ISO 9875:2001Ships and marine technology Marine echo-sounding equipment1 ScopeThis International Standard specifies the minimum operational and performance requirements, methods
28、 of testingand test results of marine echo-sounding equipment required to comply with the performance standards adopted bythe IMO Resolution A.224(VII). In addition, it takes account of IMO Resolution A.694(17) and is associated withIEC 60945.When a requirement in this International Standard is diff
29、erent from IEC 60945, the requirement in this InternationalStandard takes precedence.The purpose of echo-sounding equipment is to provide reliable information on the depth of water under a ship toaid navigation in particular in shallow water.This International Standard is applicable for ship speeds
30、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 referencesThe fo
