Graphical symbols for diagrams — Part 2: Graphical symbols

Symboles graphiques pour schémas — Partie 2: Symboles graphiques

Abstract / scope

This document specifies graphical symbols for diagrams related to industrial components, products and processing.

This document constitutes a symbol library, from which users can use the symbols or created symbol examples for use in diagrams (see Tables 1 to 149).

General rules and guidance for the preparation and presentation of graphical symbols are given in ISO 14617-1. Application rules for the symbols are shown in normative Annex A.

This document does not apply to:

— graphical symbols for fluid power objects, see ISO 1219-1 (the collective application standard of the ISO 14617 series);

— symbols of measurement and control functions such as mathematical functions and process functions;

— graphical symbols for electrotechnical objects, see the IEC 60617 database.

Symbols deleted from the previous edition of the ISO 14617 series are summarized in informative Annex B as a reference. The alphabetic index of symbols defined in this document is shown in informative Annex C.
