Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the World
Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see

This document was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory
equipment, Subcommittee SC 6, Medical gas supply systems.
This fourth edition cancels and replaces the third edition (ISO 11197:2016), which has been technically
revised. The main changes compared to the previous edition are as follows:
— editorial revision;
— change in the requirements defining the inclusion of USB outlets within medical supply units;
— addition of methods of internal cabling connections and specific tests including but not limited to
impact resistance.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

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. IEC 60601-
1:2005+A1:2012 is the basic 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 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
