TS EN ISO 11192

TS EN ISO 11192 is the standard for graphical symbols used for operator controls, gauges, tell-tales, indicators, instructions and warnings against risks in small craft. It also addresses symbols intended for engines and other equipment used on small craft of up to 24 m length of hull, helping create a consistent visual language across marine controls and displays.

Why standardised symbols matter on small craft

Graphical symbols reduce dependence on wording and support quicker recognition in compact, multilingual, or time-sensitive environments. On board a small craft, controls and status indications often need to be understood at a glance, so a standard symbol set helps manufacturers present functions such as propulsion, steering, alarms, or operating states in a clearer and more uniform way. In general technical use, this improves usability and helps avoid ambiguity between different equipment designs.

Technical areas covered by the document

• Operator controls and their associated graphical symbols
• Gauges, tell-tales and indicators
• Instructions and warning symbols
• Small craft and equipment intended for use on small craft
• Applicability to craft with a hull length up to 24 m

As a general technical context, such symbols form part of the human-machine interface of marine equipment. They support quick reading of engine, electrical, steering, cooling and safety-related functions, while the broader layout, illumination and physical design of the panel remain separate equipment-design concerns. The result is a more consistent and intuitive interface for users of small craft.
