Full title and description
Standard data element types with associated classification scheme for electric components — Part 2: EXPRESS dictionary schema (IEC 61360-2:2012). This part specifies a formal, computer-sensible dictionary data model (expressed using EXPRESS) to represent classes, properties (data element types), value domains, units and related structures for electrical and electronic component data to support information exchange, cataloguing and the IEC Common Data Dictionary (IEC CDD).
Abstract
IEC 61360-2:2012 (3rd edition) defines the EXPRESS-based dictionary schema used to model the structure and semantics of product classes, properties (DETs), data types and units for electrotechnical components. It provides the information model that underpins the IEC Common Data Dictionary and harmonizes with ISO 13584-42 to enable consistent, machine-readable exchange of product-property information across suppliers, systems and software.

Scope
This part specifies the EXPRESS dictionary schema for the representation of standard data element types, classification classes and associated metadata for electric and electronic components. It defines the three-level dictionary architecture (dictionary, basic semantic units, data element types), the type system, value formats, unit handling and mechanisms for constraints and class/property relationships. The schema is intended to be used where computer-interpretable, standardized property and class definitions are required for cataloguing, product data exchange, and integration with IEC CDD and ISO 13584-42.
Key topics and requirements
- Formal EXPRESS schema for dictionary structures, classes and properties (DETs).
- Three-level dictionary architecture and identification rules for elements.
- Definition of a comprehensive type system and data subtypes (including rational_type).
- Value format specification and lexical representations (aligned with ISO 8601 for dates/time).
- Rules for units of measurement, named and SI units, and unit string generation.
- Value constraints for properties and classes, and class/categorization distinctions.
- Exchange requirements and examples (EXPRESS-G diagrams, sample dictionary files).
- Extensions and compatibility notes with ISO 13584-42 and IEC CDD integration.
Typical use and users
Used by standards committees, product data managers, component manufacturers, cataloguers, PLM/PDM/ERP vendors, EDA and CAD tool developers, data integrators and software engineers who implement machine-readable product dictionaries. It is applied when building or mapping to the IEC Common Data Dictionary, preparing formal property definitions for supplier catalogs, or enabling standardized product-property exchange in Industry 4.0 / digital twin scenarios.
