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 (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 paragraph 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.
