Overview
EN ISO 11197:2019 - Medical supply units is a particular standard that establishes basic safety and essential performance requirements for medical supply units (also called ME equipment). It is based on IEC 60601-1:2005+A1:2012 and applies to medical supply units manufactured in a factory or assembled on site, including cabinetry and enclosures that incorporate patient care services. A party assembling components on site is considered the manufacturer. The 2019 edition supersedes EN ISO 11197:2016 and includes editorial updates and technical changes (e.g., USB outlet requirements, internal cabling methods and impact-resistance tests).
Key Topics
- Scope and definitions: Clarifies what constitutes a medical supply unit and the role of manufacturers/assemblers.
- Basic safety and essential performance: Requirements for protecting patients, users and maintenance personnel from electrical, mechanical, thermal and radiation hazards.
- Construction and internal cabling: Standards for cabinetry, enclosures, wiring methods, and mounting to ensure durability and serviceability.
- Protection against hazards: Electrical protection, mechanical strength (including impact resistance), temperature limits and prevention of hazardous outputs.
- ME systems and PEMS: Requirements for medical electrical systems and programmable electrical medical systems where applicable.
- Identification, marking and documentation: Labelling, user manuals and technical documentation required for safe installation and maintenance.
- Testing and production controls: Type and production tests, including those referenced in informative annexes (tests during production, documentation).
- Usability and risk rationale: Informative annexes provide rationale for requirements and guidance for testing and documentation.
Applications
EN ISO 11197:2019 is intended for:
- Designers and manufacturers of wall‑mounted, recessed or freestanding medical supply units and cabinetry.
- Hospital facility planners and contractors specifying or installing medical gas, vacuum, power, data and accessory services in patient rooms, operating theatres, ICUs and emergency departments.
- Installers, assemblers and on‑site integrators, who are treated as manufacturers under the standard and must ensure compliance when assembling components into enclosures.
- Maintenance, inspection and testing personnel responsible for routine checks, safety tests and conformity assessments.
Practical benefits include improved patient-safety integration, consistent requirements for medical gas and electrical outlets, clearer responsibilities for on‑site assembly, and harmonised testing to support regulatory compliance.
Related Standards
- Based on IEC 60601-1:2005+A1:2012 (general standard for medical electrical equipment).
- Refers to applicable collateral standards in the IEC 60601 family (EMC, usability, etc.).
- Notes that some collateral standards (e.g., IEC 60601-1-3, -1-8, -1-9, -1-10, -1-11, -1-12) do not apply to this particular standard.
