TS ISO 14617-1

TS ISO 14617-1 is the introductory part of the graphical-symbol system used in technical diagrams. It provides the framework needed to navigate the rest of the ISO 14617 series, covering how graphical symbols are identified through registration numbers, how they are presented and applied, and how examples are organised for practical use. It also establishes the index structure that makes the collection usable as a reference tool.

Registration numbers and index structure

The standard explains the registration-number concept used to identify graphical symbols in a consistent way. In technical drawing practice, this helps distinguish one symbol from another and supports traceable referencing across diagram documentation. Its three indexes are designed for quick lookup within ISO 14617: an alphabetical index, a registration-number index, and an index of cross-references to related items in other International Standards.

General context for diagram symbols

Graphical symbols provide a compact visual language for representing items, functions and relationships in process, machine, plant and technical system diagrams. In general technical practice, such standards help users interpret symbols consistently across drawings and disciplines. ISO 14617-1 serves as the gateway to that larger symbol system, while pointing to ISO 81714-1 for the fundamental rules governing the creation and application of graphical symbols.

• Introduces the ISO 14617 family as a whole.
• Explains the registration-number approach for graphical symbols.
• Includes alphabetical, numeric and cross-reference indexes.
• Provides examples of symbol presentation and application.
• Refers to ISO 81714-1 for fundamental creation rules.
