TS EN ISO 81714-1

TS EN ISO 81714-1 addresses the basic rules for designing graphical symbols used in the technical documentation of products. It provides a common framework for symbols appearing in drawings, instructions, maintenance documents and related technical records for industrial products, with the aim of keeping them clear, consistent and suitable for practical use.

The role of graphical symbols in technical documentation

Graphical symbols are used to shorten text, communicate information quickly, and preserve meaning across language environments. In technical documentation, symbol design affects not only appearance but also line structure, recognisability, legibility and consistency with other symbols. The focus of this standard is the basic design discipline behind those symbols: the general rules for building and using a symbol system in line with application needs.

What the scope means in practice

• It applies to graphical symbols used in technical documentation for industrial products.
• It addresses basic design rules rather than providing a catalogue of individual symbols.
• It supports clarity and consistency in technical documentation.
• It serves as a foundational approach that can work alongside broader symbol systems.

In general technical practice, well-designed graphical symbols help make assembly, operation, maintenance and safety information quicker to understand. Symbol design is therefore not just a visual matter; it also affects the accuracy of technical communication and the consistency of documents. TS EN ISO 81714-1 is positioned as a foundational part of that design framework.
