Fluid power systems and components - Graphical symbols and circuit diagrams - Part 3: Symbol modules and connected symbols in circuit diagrams - First Edition
 N 1219-3

Annotation

This part of ISO 1219 supplements ISO 1219-1 and ISO 1219-2 by specifying rules for the generation and combination of symbols of connectable components in circuit diagrams. Using these symbols, the design envelope and piping can be reduced.

These rules define the generation of symbols and their combination to represent modular built functional units, such as manifold assemblies or stacked valve assemblies or air preparation units (FRL units). The rules not only help in generating circuit diagrams but also aid and raise understanding of these diagrams by grouping and displaying symbols of connected components.

Examples for the application of these rules are included in this part of ISO 1219.

NOTE 1 In addition to terms in English and French, two of the three official ISO languages, this part of ISO 1219 gives the equivalent terms in German; these are published under the responsibility of the member body for Germany (DIN). However, only the terms and definitions given in the official languages can be considered as ISO terms and definitions.

NOTE 2 Exemplary application of the rules described in this part of ISO 1219 can be found in the Annexes. Table 1 gives an overview of which rule is applied as best practice in each Annex.
