Ships and marine technology - Marine electromagnetic compasses (ISO 11606:2000)

This International Standard specifies general requirements, type tests and individual tests for marine electromagnetic
compasses intended for steering purposes and/or taking bearings on board ships required by Chapter V of SOLAS,
1974 and the International Code of Safety for High-Speed Craft (HSC Code). The magnetic compasses
specified in this standard shall apply to the ships the overall length of which is normally not less than 24m . In this
context an electromagnetic compass is an item of electronic equipment which uses the geomagnetic field to obtain
information about the ship's heading. This information is conveyed to the main compass (which is used for steering
and taking bearings), to additional repeater indicators and, if required, to other navigational equipment.
NOTE All requirements that are extracted from the recommendations of IMO resolutions are printed in italics.

Schiffe und Meerestechnik - Elektromagnetische Kompasse für Schiffe (ISO 11606:2000)

Diese Internationale Norm legt allgemeine Anforderungen, Baumusterprüfungen und Einzelprüfungen für elektro-magnetische Kompasse fest, die zum Steuern und/oder zum Peilen an Bord von Schiffen nach SOLAS 1974, Kapitel 5 und dem Internationalen Code für die Sicherheit von Hochgeschwindigkeitsfahrzeugen (HSC Code) vorgeschrieben sind. Die elektromagnetischen Kompasse nach dieser Norm gelten für Schiffe deren Länge über alles nicht unter 24 m beträgt.
Ein elektromagnetischer Kompass ist hier eine elektronische Anlage, die das erdmagnetische Feld benutzt, um eine Information über den Schiffskurs zu erhalten. Diese Information wird in den Hauptkompass (der zum Steuern und zum Peilen benutzt wird), in zusätzliche Tochterkompasse und, falls erforderlich, in andere Navigationsanlagen übertragen.
ANMERKUNG   Alle Anforderungen, die den Empfehlungen der IMO-Resolutionen entnommen wurden, sind kursiv gedruckt.
