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.

ISO 11197:2016(E)
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 International Standard 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 MEDICAL GAS, vacuum, ANAESTHETIC GAS SCAVENGING and/or PLUME EXTRACTION SYSTEMS should be aware of
the contents of this document.
This International Standard 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, 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.
NOTE Definitions of collateral standard and particular standard can be found in IEC 60601:2005+A1:2012.
For an explanation of the special numbering in this document and more on the terms “collateral”, “particular” and
“general” standards, see 201.1.3, 201.1.4, and 201.1.5.
Annex AA contains rationale statements for some of the requirements of this International Standard. It is included
to provide additional insight into the reasoning that led to the requirements and recommendations that have been
incorporated in this International Standard. The clauses and subclauses marked with (*) after their number have a
corresponding rationale contained in Annex AA.
