Full title and description

IEC Technical Specification 62771:2012 — Information model covering the contents of IEC 81346-1 and IEC 81346-2, IEC 61175, IEC 61666 and IEC 81714-3. This TS contains a formal reference information model of the concepts and methods established in those normative documents, intended to provide a consistent data- and information-structure for technical documentation and graphical-symbols management.

Abstract

IEC/TS 62771:2012 defines a formal reference information model that captures and maps the concepts, relationships and attribute structures used across a set of IEC documentation and symbol standards (notably IEC 81346 series, IEC 61175, IEC 61666 and IEC 81714-3). It is intended to promote interoperability of documentation systems, consistent object identification and clearer representation of graphical-symbol metadata used in technical documentation workflows.

Scope

The Technical Specification provides a formal reference information model describing the principal concepts and methods used in the cited IEC standards (IEC 81346-1/-2, IEC 61175, IEC 61666 and IEC 81714-3). It is focused on modelling how identification, classification, naming and graphical-symbol metadata should be represented so that different documentation systems and tools can share and interpret technical information consistently.

Key topics and requirements

• Definition of a formal reference information model for documentation and graphical-symbol metadata.
• Mapping of concepts and relationships from IEC 81346-1/-2, IEC 61175, IEC 61666 and IEC 81714-3 into a common model.
• Attribute definitions and recommended data structures to support consistent object identification and classification.
• Guidance to support interoperability between documentation systems, symbol libraries and engineering tools.
• Normative references to the established IEC standards that form the model’s basis.

Typical use and users

Intended users include standards and documentation committees, technical authors, information-architects and software vendors that develop documentation management systems, symbol libraries, CAD and PLM/ERP integrations. It is used when implementing or harmonizing structured technical documentation, object identification schemes and graphical-symbol management across engineering domains.

Related standards

Normative and closely related documents include IEC 81346-1 and IEC 81346-2 (structuring principles and reference designations), IEC 61175 (designation of signal-bearing systems), IEC 61666 and IEC 81714-3 (graphical symbols and identification). The TS explicitly references and maps to these standards as its normative basis.

FAQ

Q: What is this standard?

A: IEC TS 62771:2012 is a Technical Specification that defines a formal reference information model covering the content and concepts used in a set of IEC standards for reference designation and graphical-symbols documentation.

Q: What does it cover?

A: It covers the conceptual data model — concepts, relationships and attribute structures — needed to represent identification, classification and graphical-symbol metadata consistently across documentation systems, and maps those concepts to the cited IEC normative standards.

Q: Who typically uses it?

A: Standards committees, documentation engineers, technical authors, tool and software vendors (CAD/PLM/PDM/document management systems), and organizations implementing structured reference-designation and symbol-management workflows.

Q: Is it current or superseded?

A: As published, IEC/TS 62771:2012 is the first edition (2012). The IEC catalogue shows the TS as published on 8 August 2012 with a listed stability date to 2026, indicating it remains the published Technical Specification up to that stability date (check IEC or national bodies for any updates after that date).

Q: Is it part of a series?

A: It is a standalone Technical Specification that explicitly references and models content from other IEC standards (notably the IEC 81346 series, IEC 61175, IEC 61666 and IEC 81714-3), and therefore functions as a companion/reference model within that family of documentation and graphical-symbol standards.

Q: What are the key keywords?

A: information model; reference designation; technical documentation; graphical symbols; IEC 81346; IEC 61175; metadata; interoperability.
