12、ternational Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee h
13、as been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical
14、 standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodi
15、es 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any
16、or all such patent rights. ISO 25861 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 6, Navigation. ISO 25861:2007(E) ISO 2007 All rights reserved v Introduction ISO 17884 “Ships and marine technology Searchlights for high-speed craft” specifies many requir
17、ements that are also applicable for this International Standard, ISO 25861 “Ships and marine technology Navigation Daylight signalling lamps”. For a clearer structure, it is proposed for the future to merge these International Standards into one International Standard with a general part and an Anne
18、x A for searchlights and an Annex B for daylight signalling lamps. INTERNATIONAL STANDARD ISO 25861:2007(E) ISO 2007 All rights reserved 1 Ships and marine technology Navigation Daylight signalling lamps 1 Scope This International Standard applies to daylight signalling lamps, which are required for

20、C.95(72). Where the wording of this International Standard is identical to that in MSC.95(72), all such text is printed in italics and the resolution and paragraph numbers are indicated in brackets. 2 Normative references The following referenced documents are indispensable for the application of th
