Full title and description

ISO 1219-3:2016 — Fluid power systems and components — Graphical symbols and circuit diagrams — Part 3: Symbol modules and connected symbols in circuit diagrams. This part of ISO 1219 specifies rules for generating and combining symbols for connectable components (for example stacked valves, manifold assemblies and air preparation units) so that modular functional units can be represented compactly in circuit diagrams, reducing piping and design envelope while improving diagram clarity.

Abstract

ISO 1219-3:2016 supplements ISO 1219-1 and ISO 1219-2 by defining the rules for symbol modules and connected symbols used in fluid-power circuit diagrams. It gives conventions for grouping and displaying connected component symbols and includes application examples to aid diagram generation and interpretation.

Scope

This part of ISO 1219 defines rules for the generation and combination of symbols of connectable components to represent modular built functional units (for example manifold assemblies, stacked valve assemblies and air preparation (FRL) units). The rules aim to reduce the design envelope and piping shown on circuit diagrams, improve readability, and provide examples of how to apply the symbol-module conventions in practice. It is intended to be used together with ISO 1219‑1 (graphical symbols) and ISO 1219‑2 (circuit diagram rules).

Key topics and requirements

• Rules for creating symbol modules that represent modular assemblies (stacked valves, manifolds, FRL units).
• Conventions for visually connecting component symbols to show physical and functional connections while minimizing piping depiction.
• Guidance on combining individual component symbols into compact connected-symbol representations.
• Examples illustrating application of the rules to typical assemblies and circuit-diagram layouts.
• Requirement to use in conjunction with ISO 1219-1 (graphical symbols) and ISO 1219-2 (circuit diagrams) for complete diagram standardization.

These topics are intended to standardize modular symbol presentation and improve clarity and interchangeability of fluid-power diagrams.

Typical use and users

Engineers and designers of hydraulic and pneumatic systems, technical illustrators and documentation authors, OEMs and component manufacturers, maintenance personnel, and standards committees use ISO 1219-3 to produce and interpret consistent circuit diagrams that represent modular assemblies compactly. It is commonly applied in design drawings, installation and service manuals, and technical training materials.

Related standards

Directly related: ISO 1219-1 (Graphical symbols for conventional use and data-processing applications) and ISO 1219-2 (Circuit diagrams). Related vocabulary and terminology are covered by ISO 5598 (Fluid power systems and components — Vocabulary). Other system-level standards for hydraulic and pneumatic safety and system rules (for example ISO 4413 / ISO 4414) are often used in conjunction with the ISO 1219 series.

FAQ

Q: What is this standard?

A: ISO 1219-3:2016 is Part 3 of the ISO 1219 series; it defines symbol-module and connected-symbol rules for representing modular fluid-power assemblies in circuit diagrams.

Q: What does it cover?

A: It covers rules for generating and combining symbols of connectable components to represent modular built functional units (examples include manifold assemblies, stacked valve assemblies and air preparation units), plus examples showing how to apply these rules.

Q: Who typically uses it?

A: System and product designers, technical illustrators, OEMs, maintenance engineers and documentation specialists working with hydraulic and pneumatic systems. Standards committees and publishers of technical drawings also rely on it for consistent diagram presentation.

Q: Is it current or superseded?

A: The ISO bibliographic entry shows ISO 1219-3:2016 as the published edition (2016) and the standard was confirmed (reviewed) in ISO’s lifecycle process; as of the last ISO confirmation it remains the current edition. Users should check national or ISO catalogues for the most recent confirmation or amendments before relying on a purchase or citation.

Q: Is it part of a series?

A: Yes — it is Part 3 of the ISO 1219 series; Part 1 covers graphical symbols and Part 2 covers circuit-diagram rules. The three parts are intended to be used together.
