TS ISO 3864-3

TS ISO 3864-3 is the Turkish listing for a standard focused on the design principles of graphical symbols used in safety signs. The subject is not simply drawing icons; it is about shaping symbols so they are clear, consistent, and usable within a safety-sign system. Graphical symbols sit at the centre of visual safety communication, where colour, shape, and pictorial meaning work together to convey warnings, prohibitions, mandatory actions, and safe-condition information.

The role of graphical symbols in safety communication

In general technical terms, a graphical symbol is a simplified visual sign that communicates meaning without relying on text. In safety applications, this matters because users may not share the same language, may need to react quickly, or may be viewing the sign at a distance or under poor conditions. Design factors such as outline clarity, proportion, contrast, and pictorial simplicity influence whether a symbol can be recognised quickly and reproduced consistently at different sizes.

Why design principles matter

From the title alone, this part of ISO 3864 is concerned with how safety-sign symbols should be designed, rather than defining the meaning of every individual symbol. That distinction is important: a safety sign system depends on both the message and the visual form that carries it. Good symbol design supports visual consistency across a family of signs, reduces ambiguity between similar symbols, and helps align the symbol with the surrounding colour and sign format. As a result, the standard serves as a design reference for creating symbols that are easier to understand and apply in safety signage contexts.
