TS 4802 ISO 7001

TS 4802 ISO 7001 is a standard concerned with public information symbols for use in public places and buildings. Its subject is the communication of needed information through non-verbal signs, so that guidance, identification and wayfinding messages can be understood more consistently across different user groups. In general technical terms, this kind of symbol system reduces reliance on language and helps make public information quicker to recognise.

What symbol-based communication does differently from text

Within this subject area, a symbol is treated not just as a graphic mark but as a carrier of a specific function. In public environments, symbols are commonly used for entrances, exits, toilets, access points, service areas and route-finding. As a general principle, such visual systems simplify information delivery, support multilingual contexts and improve immediate recognition when users need to act quickly.

What this standard covers in practical terms

• It relates to information needed in public places and buildings.
• It covers non-verbal signs.
• It focuses on the functions of those signs.
• It is linked to ISO 7001:1980 Add.1:1985 through the national adoption record.
• The standard has since been withdrawn, so it serves as a historical reference rather than a current active issue.

Symbol systems matter because readability and consistency affect how well people can navigate a space. Clarity depends on factors such as shape, contrast, simplicity and repeated use of the same meaning. Standards in this area help align symbol use across locations, but this particular record does not by itself define a new test method or a separate design regime.
