General Information
- Abstract
This Technical Report lists collective terms and codes for groups of medical devices having common features. The listing is structured so that the terms can be used for the purposes required in regulatory reporting and for communication relevant to the application of the medical device regulation.
For certain purposes in the application of the Medical Devices Directives, there is an urgent need for the development of a list of collective terms based on the identified principles to be used, for examples, as follows:
- to illustrate the scope of certificates issued by Notified Bodies when assessing which groups, families or types of medical devices are covered within a manufacturer's quality system,
- to be used to identify the range of skills and general technological abilities for which a Notified Body has been approved, and is so appointed by the relevant Competent Authority,
- for the exchanges of information between Competent Authorities when general information on individual manufacturers capabilities is notified for inclusion in the European Database for Medical Devices (EUDAMED).
For the purpose of developing sets of collective terms, Accessories to medical devices are integrated de facto in the corresponding medical device collective term.

Overview
SIST HD 60269-2:2013 – Nomenclature - Collective terms and codes for groups of medical devices – is an essential standard developed by CLC (CENELEC) for the classification and coding of medical devices. This technical report provides methodology and structure through collective terms and associated codes, making it easier to identify, catalogue, and harmonize groups of medical devices within healthcare systems, regulatory bodies, and the medical device industry.
By establishing a standardized nomenclature, this document supports consistent communication, data exchange, and traceability across all stakeholders in the medical device sector. The classification framework is aligned with related European and international standards, ensuring compliance, interoperability, and simplification of regulatory documentation.
Key Topics
- Collective Terms and Codes: Provides a framework for the grouping and identification of medical devices using standardized terms and codes.
- Classification Structure: Outlines how medical devices are categorized based on common functionality, technology, or intended use, supporting better regulatory oversight and industry alignment.
- Harmonization and Interoperability: Facilitates seamless data interchange between manufacturers, regulators, and healthcare providers by promoting the use of common nomenclature.
- Support for Electronic Records: Enables effective implementation in databases, electronic health records, and regulatory submissions by providing standardized terms and codes.
- Alignment with Other Standards: Designed to complement broader regulatory and classification frameworks such as the Global Medical Device Nomenclature (GMDN) and other IEC, CEN, and ISO standards.
- Updates to Reflect Industry Practices: The nomenclature and coding schemes are periodically reviewed and updated to reflect advancements in medical technologies and evolving regulatory requirements.
Applications
- Regulatory Submissions: Ensures consistent and accurate identification of medical devices in submissions to regulatory bodies at the national and international level.
- Procurement and Inventory Management: Facilitates efficient procurement, stock control, and inventory management within hospitals and healthcare organizations by standardizing device identifiers.
- Market Surveillance and Vigilance: Supports traceability and rapid identification of devices during recalls and post-market surveillance activities.
- Healthcare Information Systems: Enhances interoperability in health IT systems, including electronic medical records and hospital information systems, through the use of consistent device codes.
- Industry Communication: Improves clarity in communication between manufacturers, suppliers, healthcare providers, and regulators by using common terminology.
- Research and Analysis: Enables robust categorization and statistical analysis of device usage, performance, and incident reporting for evidence-based healthcare decision-making.
Related Standards
SIST HD 60269-2:2013 is used alongside several key standards to enhance consistency and technical interoperability in the field of medical devices, notably:
- ISO 15225: Nomenclature system for medical devices, providing a globally recognized framework for device identification.
- IEC 60601 series: Safety and performance of medical electrical equipment.
- GMDN (Global Medical Device Nomenclature): International system of names and codes for medical devices, aligned with CEN/TR 15133’s approach to classification.
- ISO 13485: Quality management systems for medical devices.
Practical Value
Using SIST HD 60269-2:2013 ensures that all stakeholders in the healthcare sector can precisely identify and classify medical devices, aiding regulatory compliance, improving supply chain efficiency, and supporting patient safety initiatives. Standardized nomenclature and codes streamline processes ranging from approval and procurement to surveillance and incident management, making this standard integral to both regulatory and operational excellence in the European and global medical device markets.
Keywords: CEN/TR 15133, medical device nomenclature, device coding, collective terms, medical devices classification, healthcare interoperability, regulatory compliance, medical device identification, supply chain efficiency.
