Overview
ISO 16273:2020 - Ships and marine technology - Night vision equipment for high-speed craft - specifies operational and performance requirements, and the methods of testing and required test results for night vision systems fitted to high-speed craft. The standard aligns with IMO performance standards (IMO Resolution MSC.94 (72)) and supports implementation of the IMO International Code of Safety for High-Speed Craft (HSC Code), Chapter 13. It covers both thermal imaging and active image‑intensifier systems and defines how equipment shall perform, be tested, marked, installed and maintained.
Key topics and technical requirements
- Performance requirements: functions and availability, continuous operation, detection range, field of view, pan/tilt ranges and panning speeds, stabilization against vessel motions, heading marker indication and clear view requirements.
- Image and sensor criteria: line of sight, instantaneous field of view, optical interference limits, minimum temperature difference perceived (MTDP) for thermal imagers.
- Controls, ergonomics and presentation: human‑machine interface, single operator actions, presentation of information and software considerations.
- Environmental and durability tests: shock, roll and pitch, wind endurance, optical interference tests, EMC/performance checks and resistance to environmental conditions.
- Laboratory tests and sea trials: specific test procedures for thermal imagers and active image‑intensifier systems, sea trial protocols, standard test targets and required test results.
- Installation, marking and documentation: identification, installation guidance, maintenance requirements and required documentation for compliance and operational use.
- Annexes: normative procedures such as MTDP measurement (Annex D) and stabilisation tests for thermal and image‑intensifier systems (Annexes E and F), plus informative guidance for range prediction and sea trial records.
Practical applications and who uses this standard
ISO 16273:2020 is used to ensure safe night navigation and reliable situational awareness on high‑speed craft. Typical users include:
- Manufacturers of night vision systems (thermal imagers, image intensifiers) for design and compliance testing.
- Shipbuilders and system integrators for correct installation and interface with vessel systems.
- Classification societies, flag states and maritime regulators for certification and acceptance against IMO HSC Code requirements.
- Operators, crew trainers and procurement teams for specifying equipment, planning sea trials and maintenance regimes.
- Test laboratories executing the standardised laboratory and sea trial methods.
