Overview
ISO 3767-2:2016 standardizes graphical symbols for operator controls and other displays specifically for agricultural tractors and machinery. Part of the ISO 3767 series, this edition is an extensive technical revision that adds many new symbols. It defines how symbols should be presented, reproduced, grouped and adapted for electronic displays so symbols communicate clearly and consistently across international markets.
Key topics and requirements
- Scope and purpose: Symbols apply to agricultural tractors and machinery as classified in ISO 3339-0 and complement the common symbols in ISO 3767-1.
- Symbol usage rules: Symbols shall be used as shown in the standard; selected outline symbols may be filled for clarity. Minor graphical modifications (line width, rounded corners) are allowed as long as the symbol’s essential meaning remains unchanged.
- Orientation and scaling: Symbols must appear in the prescribed orientation unless specific rotation/mirroring is allowed. Sizing guidance references IEC 80416-1 to ensure legibility and correct visual relationships when symbols are grouped.
- Colour coding for illuminated displays:
- Red - failure, serious malfunction, immediate attention required
- Yellow/amber - condition outside normal limits
- Green - normal operating condition
- Reproduction requirements: Symbols cast, moulded, embossed or stamped must be visually distinct without reliance on colour.
- Location and relation to controls: Symbols shall be placed on or adjacent to the control/display they identify and arranged so control movement toward a symbol corresponds to the function depicted.
- Digital adaptation: Symbols may be adapted into icons for GUIs and reconfigurable displays following ISO 80416-4, preserving the original symbol’s visual impression.
- Development of new symbols: New symbol proposals must follow ISO 3767-1 Annex A and consult ISO 7000/IEC 60417 databases to avoid duplication; proposed symbols require a short explanation of intended use.
- Registration references: Where applicable, ISO/IEC registration numbers (ISO 7000, IEC 60417) are shown for registered symbols.
Applications and users
ISO 3767-2 is essential for:
- Tractor and agricultural machinery manufacturers (control panels, dashboards)
- Human factors, UI/UX and product designers (physical and digital displays)
- Safety and compliance engineers implementing international marking requirements
- Service and training organizations ensuring consistent operator communication
- Regulators and standards bodies harmonizing machine labeling
Practical uses include control panel design, in-cab display iconography, operator manuals, safety labeling, and global product certification.
