TS ISO 14617-2

TS ISO 14617-2 defines a standardized symbol library for graphical symbols used in diagrams related to industrial components, products and processes. It provides a common visual language that helps technical drawings and process diagrams represent the same object consistently across different teams and disciplines.

In general technical terms, graphical symbols are used to express equipment, functions and interconnections with simplified signs instead of extensive text. This makes complex layouts faster to read, improves the exchange of documentation between engineering groups, and helps preserve consistent meaning from design through operation. This part of ISO 14617 supplies the symbols themselves; general rules for preparation and presentation are given in ISO 14617-1, while application rules are set out in normative Annex A.

What is included, and what is handled elsewhere

• Graphical symbols for fluid power objects are outside the scope of this part; ISO 1219-1 is the collective application standard for that area.
• Symbols for measurement and control functions, including mathematical and process functions, are not covered here.
• Graphical symbols for electrotechnical objects are provided in the IEC 60617 database.
• Symbols deleted from the previous edition of the ISO 14617 series are summarized for reference in informative Annex B.
• An alphabetical index of the symbols defined in this document is given in informative Annex C.

In practice, this standard is a reference for symbol consistency rather than a test method or equipment specification. It is especially relevant wherever industrial schematics, machinery documentation, and process-related drawings need a shared and unambiguous symbol set.
