Graphical symbols for diagrams - Part 2: Graphical symbols

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
