TS EN ISO 18542-2

TS EN ISO 18542-2 addresses the implementation requirements for standardized process handling in road-vehicle repair and maintenance information terminology. This part focuses on the Terminology Management System and the Registration Authority, providing the technical and organisational basis for keeping agreed RMI terms consistent and searchable across vehicle manufacturers’ information services.

In the ISO 18542 series, the goal is to support a common vocabulary for service and information retrieval. In general technical terms, agreed terminology reduces ambiguity when independent operators search for repair information, because the same concept can be indexed and published under a controlled, shared term rather than multiple local variants.

How the terminology system and the registration authority fit together

This part is about managing agreed terminology, not about creating the underlying term framework itself. A Terminology Management System provides the technical environment for storing, organising, and linking terms. The Registration Authority is the body responsible for maintaining and publishing the agreed terminology so that it remains usable over time.

That distinction matters in multi-brand, multilingual RMI environments: the content of the shared vocabulary is one issue, while its governance and publication are another. By defining implementation requirements for these functions, the standard supports more consistent indexing, better search behaviour, and more reliable access to maintenance information. It is aimed at technical stakeholders implementing the M/421 mandate context.

• Technical implementation requirements for the Terminology Management System
• The Registration Authority’s maintenance and publication role
• A standardised approach that supports search in RMI websites
• An implementation-focused part separate from the agreement framework in ISO 18542-1
