Overview
ISO 11192:2005 - Small craft - Graphical symbols specifies standardized graphical symbols for operator controls, gauges, tell‑tales, indicators, instructions and warnings used on small craft (up to 24 m hull length) and for engines and equipment intended for those craft. The standard helps convey operational information and safety messages independently of language, reducing misinterpretation on board recreational and commercial small boats.
Key topics and requirements
- Scope and intent: Symbols cover media, conditions, boat components, marine engine components, boat and engine operations, warning/caution/malfunction indicators and miscellaneous items relevant to small craft.
- Symbol colours: Where colour is used, red denotes danger/unsafe/hot and yellow/orange denotes caution. Colour use for safety follows ISO 3864‑1.
- Design and application guidance: ISO 11192 references principles and databases for symbol originals, sizing, positioning and restyling (see ISO 7000, ISO 7010, IEC 60417, IEC 80416‑1).
- Symbol categories: Examples include media (fresh water, fuel, diesel, LPG), conditions (temperature, pressure, rotational speed, fuel level), boat components (lights, horn, pumps, hydraulic systems, wipers), engine components (engine, transmission, battery, filters, heat exchangers), and operational controls (engine start/stop, choke, fuel shut‑off).
- Referenced resources: The standard relies on normative references such as ISO 3864‑1, ISO 7000, ISO 7010, ISO 17724 and IEC symbol standards for consistent implementation.
Applications and users
ISO 11192:2005 is practical for:
- Boat and marine‑equipment manufacturers - to label controls, gauges and warnings on vessels up to 24 m and on engines/accessories intended for such craft.
- Naval architects and systems designers - to create control panels, instrument clusters and user interfaces that meet international symbol conventions.
- Marine engine and component suppliers - to mark fuel, coolant, oil and filtration systems consistently.
- Regulatory bodies, surveyors and safety officers - to evaluate compliance and clarity of onboard signage and indicators.
- Technical writers and user manual authors - to reference correct symbols for operation and safety instructions.
Adopting ISO 11192:2005 improves usability, safety and international interoperability of small craft controls and warnings, reducing language barriers and enhancing emergency response clarity.
