The work of preparing I
11、nternational Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison
12、 with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of tech
13、nical committees is to prepare International Standards. Draft International Standards adopted by 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 draw
14、n 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 or all such patent rights. ISO 25861 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 6, Navigation. BS
15、 ISO 25861:2007vIntroduction ISO 17884 “Ships and marine technology Searchlights for high-speed craft” specifies many requirements that are also applicable for this International Standard, ISO 25861 “Ships and marine technology Navigation Daylight signalling lamps”. For a clearer structure, it is pr
16、oposed for the future to merge these International Standards into one International Standard with a general part and an Annex A for searchlights and an Annex B for daylight signalling lamps. BS ISO 25861:2007blank1Ships and marine technology Navigation Daylight signalling lamps 1 Scope This Internat
17、ional Standard applies to daylight signalling lamps, which are required for certain ships pursuant to Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended, and Chapter 8 of the International Code of Safety for High-Speed Craft, in force, in accordance wit
18、h the Performance Standards for Daylight Signalling Lamps IMO Resolution MSC.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
