Overview
ISO/FDIS 11197:2026 – Medical Supply Units specifies requirements for the basic safety and essential performance of medical supply units (MSUs) in healthcare environments. Medical supply units are integral parts of healthcare facilities, providing services such as electrical power, communication connections, lighting, medical gases, and liquids at the point of care. This standard applies to MSUs both factory manufactured and those assembled on site, including cabinetry, joinery, and enclosures that form part of patient care services.
Developed by ISO Technical Committee 121/SC 6, this standard replaces previous editions to reflect technological advancements and the evolution of healthcare facility needs-including requirements for both temporary and permanent healthcare installations. It covers MSUs used in all clinical environments and addresses the marking, performance, and testing to ensure the optimal safety and functionality of these critical devices.
Key Topics
ISO/FDIS 11197 provides comprehensive requirements and guidelines for the following key areas:
- Basic Safety and Essential Performance: Outlines general and particular requirements for MSU safety, drawing on the foundational IEC 60601-1 medical electrical equipment standard.
- Design, Manufacturing, and Assembly: Applies to MSUs whether built in manufacturing facilities or assembled at healthcare premises. Defines the manufacturer’s responsibilities, including on-site assembly.
- Electrical and Gas Services Integration: Specifies requirements for electrical power outlets, communication systems, light fixtures, as well as integration of medical gases, vacuum, and even plume evacuation systems.
- Protection against Hazards: Contains measures to reduce risks associated with electrical, mechanical, temperature-related, radiation, and other hazards.
- Identification and Marking: Requires clear marking of all MSU components, connectors, terminal units, and attachable parts, with specific labelling for different services (e.g., medical gas, power outlets, liquids).
- Testing and Documentation: Mandates rigorous testing procedures and traceable documentation to demonstrate compliance with safety and performance requirements.
Applications
Medical Supply Units (MSUs) designed under ISO/FDIS 11197 are critical for a wide variety of clinical settings, supporting clinical workflows and patient safety. Practical applications include:
- Hospital Bed Areas: Bedhead service modules and wall supply units delivering power, gas, data, and communication at patient bedsides.
- Operating Theatres and ICUs: Ceiling pendants, columns, beams, or booms that allow flexible and safe distribution of services to critical care environments.

Introduction
Many healthcare facilities use surface-mounted or recessed containment systems and enclosures for
accommodating and displaying essential patient care services. These are known as medical supply units.
This document specifies requirements for medical supply units manufactured in factories or assembled from
components on site.
It is intended for use by those persons involved in the design, construction, inspection, testing, maintenance
and operation of healthcare facilities as well as those manufacturing, assembling and installing medical supply
units.
Persons involved in the design, manufacture, installation, maintenance and testing of equipment intended to
be connected to gas for medicinal use, medical device gas, vacuum, anaesthetic gas scavenging and/or plume
extraction systems should be aware of the contents of this document.
This document is a particular standard, based on IEC 60601-1:2005+A1:2012+A2:2020. IEC 60601-
1:2005+A1:2012 +A2:2020 is the general standard for the safety of all medical electrical equipment used by or
under the supervision of qualified personnel in the general medical and patient environment; it also contains
certain requirements for reliable operation to ensure safety.
IEC 60601-1:2005+A1:2012+A2:2020 has associated collateral standards and particular standards. The
collateral standards include requirements for specific technologies and/or hazards and apply to all applicable
equipment, such as medical systems, electromagnetic compatibility (EMC), radiation protection in diagnostic
X-ray equipment, software, etc. The particular standards apply to specific equipment types, such as medical
electron accelerators, high frequency surgical equipment, hospital beds, etc.
Where a healthcare facility is developed for temporary use, such as in a pandemic or other natural disaster,
the basic principles of this document shall apply. Once the stage of critical use of the facility has normalised
the product remaining in use shall fulfil the requirements of this document.
NOTE Definitions of collateral standard and particular standard can be found in
IEC 60601:2005+A1:2012+A2:2020.
Annex AAnnex A contains rationale statements for some of the requirements of this document. It is included
to provide additional insight into the reasoning that led to the requirements and recommendations that have
been incorporated in this document.

Introduction
Un grand nombre d’installations de soins utilisent des systèmes et des enveloppes de confinement montés en
saillie ou encastrés, destinés à loger et à présenter les principaux services de soins aux patients. Ces systèmes
et enveloppes sont appelés gaines techniques à usage médical.
Le présent document définit les exigences relatives aux gaines techniques à usage médical fabriquées en usine
ou montées sur site à partir de composants.
Il est destiné à être utilisé par les personnes impliquées dans la conception, la construction, l’inspection,
les essais, la maintenance et l’exploitation des installations de soins ainsi que par celles qui fabriquent,
assemblent et installent les gaines techniques à usage médical.
Il convient que les personnes impliquées dans la conception, la fabrication, l’installation, la maintenance
et les essais des appareils destinés à être raccordés à des systèmes de distribution de gaz médicaux, de gaz
dispositif médical et de vide, ainsi qu’à des systèmes d’évacuation de gaz d’anesthésie et/ou des effluents gazeux
soient informées du contenu du présent document.
Le présent document est une norme particulière, qui repose sur l’IEC 60601-1:2005+A1:2012+A2:2020.
L’IEC 60601-1:2005+A1:2012+A2:2020 est la norme générale relative à la sécurité de tous les appareils
électromédicaux utilisés par ou sous la supervision d’un personnel qualifié dans l’environnement médical
général et dans l'environnement du patient. Elle comporte également certaines exigences relatives à la
fiabilité de fonctionnement, afin de garantir la sécurité.
L’IEC 60601-1:2005+A1:2012+A2:2020 est associée à des normes collatérales et à des normes particulières.
Les normes collatérales comportent des exigences relatives à des technologies spécifiques et/ou à des
dangers, et s’appliquent à tous les équipements concernés, tels que les systèmes médicaux, la compatibilité
électromagnétique (CEM), la radioprotection dans les appareils à rayonnement X de diagnostic, les logiciels,
etc. Les normes particulières s’appliquent à des types d’appareils spécifiques, tels que les accélérateurs
d’électrons à usage médical, les équipements chirurgicaux à haute fréquence, les lits d’hôpitaux, etc.
Les principes de base du présent document doivent s’appliquer lorsque des installations de soins sont mises
en place pour une utilisation temporaire, comme dans le contexte d’une pandémie ou d’une catastrophe
naturelle. Une fois le stade d’utilisation critique de l’installation passé, les produits continuant à être utilisés
doivent respecter les exigences du présent document.
