Overview
EN ISO 18542-2:2014 (CEN adoption of ISO 18542-2:2014) specifies the procedural and technical requirements for implementing a standardized terminology process for automotive repair and maintenance information (RMI). It defines what a Terminology Management System (TMS) must deliver and sets the responsibilities and requirements for the Registration Authority (RA) that maintains and publishes the agreed RMI terminology. This part of the ISO 18542 series supports consistent, secure exchange of RMI across vehicle manufacturers, independent repairers and digital systems.
Key topics and technical requirements
The standard addresses the lifecycle, architecture and operational constraints of a TMS and RA, covering principal areas including:
- Overall system architecture
- Conceptual architecture and role/data models for terminology governance.
- System infrastructure
- IT infrastructure components, database management and security requirements.
- User interface
- Graphical and programmatic interfaces for editors, reviewers and consumers of terminology.
- Data management
- Meta-object models, data exchange formats and data management services to ensure consistent terminology storage and retrieval.
- Application and workflow management
- Process steps for proposal, evaluation, review, translation, release and publication of terms under RA control.
- Operation and support
- Availability, system administration, change and release management and operational support expected of a TMS/RA.
The document also references the Digital Annex and how ISO 18542 integrates with vehicle RMI systems and related security and legislative requirements.
Practical applications and users
EN ISO 18542-2:2014 is practical for organizations and stakeholders involved in automotive RMI standardization and implementation:
- Registration Authorities (RAs) - to define roles, responsibilities and technical platform requirements for administering the agreed terminology.
- TMS vendors - to design or certify commercial-off-the-shelf (COTS) terminology management solutions that meet ISO requirements.
- Vehicle manufacturers and suppliers - to ensure consistent terminology publishing and compliance with regulatory mandates (e.g., EC Mandate M/421).
- Aftermarket and independent repairers - to access standardized, reliable terminology that improves information interoperability.
- Regulators and standards bodies - to reference a consistent implementation framework for legislation on RMI access.
Related standards
This part is intended to be used alongside other ISO 18541 and ISO 18542 documents:
- ISO 18542-1 - General information and use case definition (terminology process framework)
- ISO 18541-1 to -4 - RMI system requirements, technical, UI and conformance testing
EN ISO 18542-2:2014 is essential for organizations implementing standardized RMI terminology workflows and for software vendors building compliant TMS platforms.
