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.
Die Mindestleistungsanforderungen, die Prüfverfahren und die Darstellung der Prüfergebnisse für Echolotanlagen der Seeschifffahrt, die die Wassertiefe unter einem Schiff durch Aussendung akustischer Impulsenergie und Messung des Echos ermitteln, sind festgelegt.
