14、ardization) 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 has been established has the right
15、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 standardization. International St
16、andards 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 bodies for voting. Publication as an I
17、nternational 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 or all such patent rights. ISO 178
18、84 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 6, Navigation.

29、the maximum 3.6 tenth-peak divergence tangular extent of all the radius vectors of the polar curve of luminous intensity in the specified plane having lengths greater than 10 % of the maximum 4 Requirements 4.1 Required functions and their availability At night, searchlights shall be capable of loca
30、ting objects within a sufficient distance from ones own craft. The searchlights shall be provided with an electrical, hydraulic or pneumatic remote control for pan and tilt movement. 4.2 Permanent operation and life duration Searchlights shall be suitable for permanent operation. When tested in acco
31、rdance with 5.3, a life duration of the illuminant of at least 100 h shall be reached. 4.3 Luminous intensity The luminous intensity in the focused position of searchlights shall be minimally 2 10 6cd. This equals an illumination of 5,6 lx at a distance of 600 m with an atmospheric transmission of 0
32、,8. The luminous intensity of searchlights shall have its maximum in the centre of the luminous intensity distribution. With focus in any position, a homogenous luminous intensity distribution shall be ensured, i.e. the central spot area with at least 80 % of the maximum luminous intensity shall sho
33、w no position with less than 80 % of the maximum luminous intensity. BSISO17884:2004 3The half-peak divergence hshall be between 3 and 8, and the tenth-peak divergence tshall not exceed 14. The half-peak divergence hmay be smaller than 3 if focusing is possible during operation. In case of a non-cir
34、cular beam profile, the longer axis of the profile shall be orientated horizontally. 4.4 Chromaticity of the emitted light The chromaticity of the emitted light of searchlights shall lie within corner coordinates in the International Commission on Illumination (CIE) chromaticity diagram, see Table 1
