TS EN ISO 81714-1

TS EN ISO 81714-1 sets out the basic rules for designing graphical symbols intended for use in the technical documentation of products. Its focus is not merely on how a symbol looks, but on the design principles that help a symbol remain clear, consistent, and understandable across technical documents.

Why graphical-symbol design matters in technical documentation

Graphical symbols are used in product documentation to reduce text, communicate information efficiently, and support readability in drawings, manuals, and maintenance documents. In this context, the key issue is function rather than decoration: line structure, proportions, and visual consistency must support correct interpretation. This part of ISO 81714 provides a general framework for designing such symbols so they can be used coherently in technical product documents.

What the scope covers in practice

The standard covers basic rules for the design of graphical symbols, taking into account essential application needs. In practical terms, it gives a general design framework for symbols used in technical documentation, rather than a catalogue of product-specific symbols. The referenced drafting and character standards form part of the broader technical-documentation environment that supports legibility and consistent presentation.
