Full title and description

ISO 14617-3:2002 — Graphical symbols for diagrams — Part 3: Connections and related devices. This part specifies graphical symbols for functional connections, mechanical links, pipelines and related devices such as connection joints, ports, terminals, quick‑release couplings and connectors, for use in technical diagrams and engineering documentation.

Abstract

This standard defines a set of standardized graphical symbols for representing connections and related devices on technical diagrams. It is intended to harmonize symbol use across mechanical, process and pipeline diagrams and to be used together with the general rules and index information provided in other parts of ISO 14617 and in ISO 81714-1.

Scope

ISO 14617-3:2002 covers the graphical symbols used to represent functional connections and related devices in diagrams: mechanical links, pipelines, connection joints, ports, terminals, quick‑release couplings, connectors and similar items. It is intended for use where clear, standardized depiction of connections is required and should be used in conjunction with Part 1 (general information and indexes) and ISO 81714-1 (rules for creation and application of graphical symbols).

Key topics and requirements

• Standardized graphical symbols for functional connections (pipes, links, terminals, ports).
• Symbols for connection joints, quick‑release couplings and connectors.
• Compatibility and cross‑reference with ISO 14617-1 (indexes and registration numbers) and ISO 81714-1 (symbol creation and application rules).
• Guidance for diagram authors to ensure consistent representation of connections across technical documentation.
• Registration numbers and identification rules for symbols as part of the ISO 14617 family.

Typical use and users

Used by engineers, technical illustrators, CAD specialists, documentation authors and standards administrators who create or maintain mechanical, process and pipeline diagrams. Typical application areas include process and plant engineering, mechanical system design, technical manuals, installation diagrams and any documentation that requires unambiguous depiction of connections and related devices.

FAQ

Q: What is this standard?

A: ISO 14617-3:2002 is the Part 3 publication in the ISO 14617 series providing standardized graphical symbols for connections and related devices on technical diagrams.

Q: What does it cover?

A: It covers symbols for functional connections, mechanical links, pipelines and related devices (connection joints, ports, terminals, quick‑release couplings and connectors) and how these symbols are to be used in diagrams, in coordination with the general rules in other parts of the ISO 14617 family and ISO 81714-1.

Q: Who typically uses it?

A: Engineers, CAD and drawing specialists, technical authors and documentation teams producing process, mechanical and piping diagrams who need consistent, internationally recognized symbol conventions.

Q: Is it current or superseded?

A: ISO 14617-3:2002 has been withdrawn. ISO indicates the part is withdrawn and later work in the ISO 14617 family (including updated parts published in 2025) supersedes or revises aspects of the series. The withdrawal/supersession is recorded by ISO; an example withdrawal action for the part is noted in national registries (withdrawal recorded in 2025). Consult the latest ISO 14617 parts for current symbol lists.

Q: Is it part of a series?

A: Yes — it is one part of the multipart ISO 14617 series (Graphical symbols for diagrams). Use it together with ISO 14617-1 (indexes), ISO 14617-2 and the other numbered parts for a complete symbol library and application rules.

Q: What are the key keywords?

A: Graphical symbols, diagrams, connections, connectors, ports, joints, quick‑release coupling, pipelines, ISO 14617.
