Foreword

This standard is identical with ISO 11606:2000 "Ships and marine technology - Marine electromagnetic compasses" (in English).

This standard is equivalent to translate ISO 11606:2000.

The relative standard ISO 11606:2000 made the following editorial changes.

--- Preface and introduction are not included;

--- "This International Standard" is, to "present standard" in this standard;

--- Where there are existing national standards equivalent to international standards, and all references to the national standards;

--- Identification decimal "and" to ".";

--- Incorporates ISO 2005 to ISO 11606 errata content;

--- Of expression in accordance with the provisions of GB/T 1.1-2000 made editorial changes.

Appendix A of this standard is an informative annex.

The standard proposed by China State Shipbuilding Corporation.

This standard by the National Standardization Technical Committee boat ocean nautical instruments Technical Committee (SAC/TC12/SC5) centralized.

This standard was drafted. Technical and Economic Research Institute of China Shipbuilding Industry.

1 Scope

This standard specifies the line with "the 1974 International Convention for the Safety of Life at Sea" (SOLAS Convention) Chapter V chapter "International HSC Regulation General requirements for the structure and performance "(HSC Code), for the determination of the direction of steering and marine magnetic compass, type tests and individual inspection Inspection requirements. Specified in this standard applies to electromagnetic compass total length of not less than 24m of the ship. Electromagnetic compass is the use of the Earth's magnetic field Get Ship heading to the electronic device information, the information will be transmitted to the main measurement direction for steering and compass, attached to the main compass repeater and Other needs of navigation equipment.

NOTE. In this standard where the citation IMO resolutions are printed in italics.
