Overview
SIST ISO 7001:2023 - Graphical symbols - Registered public information symbols is the fourth edition of the international standard that defines a library of internationally validated public information symbols for use in public signage and wayfinding. The standard is applicable across all locations and sectors accessible to the public, except where sector-specific regulations apply (for example, safety signs and traffic signs on public roads). Symbols are provided as original, scalable designs and may be used alone or together with text to improve comprehension.
Key topics and technical requirements
- Scope and exclusions: Applies to public information symbols (PI symbols) but explicitly excludes safety signs and regulated sectors (e.g., road traffic signage).
- Symbol library and categorization: Symbols are organized into categories - PF (public facilities), TF (transport facilities), TC (tourism, culture and heritage), SA (sporting activities), CF (commercial facilities), BP (behaviour of the public), and AC (accessibility). New accessibility symbols and additional PI codes were added in this edition.
- Design rules:
- Symbols are designed to be scalable for a variety of applications (from small notices to large wayfinding signs).
- Arrows: The direction arrow (PI PF 030) must be used only in combination with another symbol or text to indicate directional movement; other arrow uses are specified with each symbol.
- Colour & contrast: Symbols may be reproduced in any colour but must avoid the safety-colour/shape combinations defined in ISO 3864‑1 (to prevent confusion with safety signs). Avoid green/white combinations for arrows to prevent confusion with evacuation signage.
- Negation: Two negation devices are defined - a diagonal negation bar (top-left to bottom-right) for whole-symbol prohibition and a negation cross for negating elements. Negation marks are normally red and must not include a surrounding circle (so as not to resemble safety signs).
- Validation & evolution: Symbols in the standard have been validated by testing methods (ISO 9186 series referenced) or established international use. The standard is maintained electronically via the ISO Online Browsing Platform.
Practical applications and users
SIST ISO 7001:2023 is directly useful for:
- Signage designers and graphic designers creating public wayfinding and information systems
- Architects, facility and transport planners specifying signage for airports, train stations, malls, hospitals, museums, and public buildings
- Sign manufacturers and wayfinding consultants implementing consistent, scalable symbol artwork
- Public authorities and accessibility specialists aiming to improve comprehension and inclusivity of public information
- Technical committees developing industry-specific symbols to ensure single-meaning consistency
Typical use cases: indoor/outdoor wayfinding, maps, digital kiosks, service directories, tourism signage, and accessibility information panels.
