TS EN ISO 15225/A1

TS EN ISO 15225/A1 is an amendment to a nomenclature standard used for regulatory data exchange in the field of medical devices. It concerns the controlled naming structure that supports consistent identification, coding, and exchange of device-related information across regulatory and information systems. In practical terms, such nomenclature systems help different organisations describe the same device in a comparable way for registration, surveillance, database management, and administrative data handling.

What a medical device nomenclature system does

In medical device work, a nomenclature is different from free-text product description. It provides standardised terms, and sometimes codes, so that similar products can be grouped and identified consistently. This improves data quality, searchability, matching, and reporting across registries and electronic systems. In general technical terms, nomenclature is about naming control, while classification is about arranging items into categories; the two are related but not identical.

Why this A1 document matters as an amendment

This record is an amendment to a parent standard, so it should be read as part of the broader EN ISO 15225 nomenclature framework rather than as a standalone full specification. Amendment documents commonly update terminology, clarify usage, or align the existing system with revised regulatory or data-exchange needs. Because the full scope text is not available here, it would not be reliable to state exactly which clauses or entries were changed.

• It is associated with controlled terminology intended to support a common language for regulatory data exchange.
• It helps medical devices be identified consistently across different organisations and information systems.
• Using standardised names instead of free text improves consistency in coding, matching, and reporting.
• As an amendment, it should be understood together with the main standard’s nomenclature framework.
