TS EN ISO 15225/A1

TS EN ISO 15225/A1 is an amendment to a standard concerned with the technical specification of a nomenclature system for medical devices used for regulatory data exchange. Its subject is the construction of a controlled terminology that allows the same device to be described consistently across organisations, supporting structured regulatory information flows and more coherent data handling.

What a medical device nomenclature is for

In the medical device field, nomenclature is more than a list of names. It is a controlled terminology designed to identify devices in a regulatory context. Such a system helps manufacturers, suppliers, health care providers and regulatory authorities refer to the same product in a consistent way. The standard addresses the specification and guidance for building that terminology; it is not simply a product catalogue and does not, by itself, describe every individual device type.

Why the distinction matters in regulatory exchange

• It supports a common language for international exchange of regulatory data.
• It improves terminology consistency in device registration, notifications and related information systems.
• It helps reduce ambiguity when the same device is described differently across markets or institutions.
• It provides a conceptual framework for creating and maintaining the nomenclature, which is important for adding new terms and managing existing ones.

Because this listing is an A1 amendment, it should be understood as modifying the parent standard rather than replacing its technical subject. In general technical terms, controlled nomenclatures are important wherever databases, reporting systems and regulatory workflows need stable, interoperable product descriptions.
