Overview

EN 81714-3:2001 (adoption of IEC 81714‑3:1998) specifies requirements for the classification of connect nodes and networks used with graphical symbols in technical product documentation. The standard defines how connect nodes-points where connections are made or represented-are assigned to graphical symbols that represent functional and product concepts, and how those nodes and networks are encoded for clear, consistent documentation. Basic rules are given in ISO/IEC 11714‑1.

Key topics and requirements

• Classification of connect nodes: Defines the principles for categorizing connection points associated with graphical symbols to reflect function and product structure.
• Network classification: Sets out how networks (groups of interconnected nodes) are identified and organized in documentation.
• Encoding rules: Requires consistent encoding of node and network information so symbols carry unambiguous connection data.
• Alignment with IEC/CENELEC practice: EN 81714‑3 mirrors IEC 81714‑3:1998 and is intended for use in European electrotechnical documentation.
• Applicability to symbol libraries: Supports standardized symbol sets and digital symbol libraries used in CAD and documentation tools.

(Note: this summary reflects the scope and content described in the official EN/IEC documents; it does not reproduce the full technical specification.)

Applications

EN 81714‑3 is practical for any organization producing technical product documentation where accurate representation of connections is essential:

• Wiring diagrams, circuit and schematic drawings
• Equipment installation and maintenance manuals
• Telecommunications and networking diagrams
• CAD symbol libraries and documentation templates
• Product certification and compliance documentation

Using EN 81714‑3 improves clarity in technical documentation, reduces misinterpretation of connection points, and supports interoperability between engineering, manufacturing and maintenance teams.

Who should use this standard

• Technical authors and documentation specialists
• Electrical, electronics and telecommunications engineers
• Product designers and systems integrators
• CAD library managers and technical illustrators
• Quality, compliance and regulatory teams in electrotechnical industries

Related standards

• IEC 81714‑3:1998 – original international text adopted as EN 81714‑3:2001
• ISO/IEC 11714‑1 – referenced for basic rules governing graphical symbols and their use

Using EN 81714‑3 alongside symbol design guidelines ensures consistent, searchable, and standards-compliant technical documentation for electrotechnical products and networked systems.
