9、 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 has been est

10、ablished 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 standardiz

11、ation. 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 bodies for voti

12、ng. 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 or all such

14、ce requirements, methods of testing and required test results 1 Scope This International Standard applies to operational and performance requirements and methods of testing for night vision equipment fitted to high-speed craft in accordance with the International Code of Safety for High-Speed Craft

15、(HSC code), Chapter 13, of the International Maritime Organisation (IMO) and the IMO performance standards MSC.94 (72) for night vision equipment for HSC. All texts of this International Standard, whose wording is identical to that in IMO MSC.94 (72), are printed in italics and the resolution and pa

16、ragraph numbers are indicated in brackets. It is expected that both performance requirements and test procedures will need to be reviewed in the near future as data on candidate night vision systems are accumulated and correlated with performance. 2 Normative references The following referenced docu
