MEDICAL ELECTRICAL EQUIPMENT –

Part 1-12: General requirements for basic
safety and essential performance –
Collateral Standard: Requirements for medical electrical
equipment and medical electrical systems intended for use
in the emergency medical services environment

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International standard IEC 60601-1-12 has been prepared by a joint working group of
IEC subcommittee 62A: Common aspects of electrical equipment used in medical practice, of
IEC technical committee 62: Electrical equipment in medical practice, and ISO subcommittee
SC3: Lung ventilators and related devices, of ISO technical committee 121: Anaesthetic and
respiratory equipment.
This first edition constitutes a collateral standard to IEC 60601-1 (third edition): Medical
electrical equipment – Part 1: General requirements for basic safety and essential
performance hereafter referred to as the general standard.

---------------------- Page: 6 ----------------------
IEC 60601-1-12:2014 © IEC 2014 – 5 –
The text of this collateral standard is based on the following documents:
FDIS Report on voting
62A/932/FDIS 62A/938/RVD

Full information on the voting for the approval of this collateral standard can be found in the
report on voting indicated in the above table. In ISO, this International Standard has been
approved by 18 P-members out of 19 having cast a vote.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
In the 60601 series of publications, collateral standards specify general requirements for
safety applicable to:
– a subgroup of MEDICAL ELECTRICAL EQUIPMENT (e.g. radiological equipment); or
– a specific characteristic of all MEDICAL ELECTRICAL EQUIPMENT, not fully addressed in the
general standard (e.g. ALARM SYSTEMS).
In this collateral standard, the following print types are used:
– requirements and definitions: roman type.
– test specifications: italic type.
informative material appearing outside of tables, such as notes, examples and references: in smaller type.
–
Normative text of tables is also in a smaller type.
– TERMS DEFINED IN CLAUSE 3 OF THE GENERAL STANDARD, IN THIS COLLATERAL STANDARD OR AS
NOTED: SMALL CAPITALS.
In referring to the structure of this standard, the term
– “clause” means one of the numbered divisions within the table of contents, inclusive of all
subdivisions (e.g. Clause 7 includes subclauses 7.1, 7.2, etc.);
– “subclause” means a numbered subdivision of a clause (e.g. 7.1, 7.2 and 7.3.1 are all
subclauses of Clause 7).
References to clauses within this standard are preceded by the term “Clause” followed by the
clause number. References to subclauses within this collateral standard are by number only.
In this standard, the conjunctive “or” is used as an “inclusive or” so a statement is true if any
combination of the conditions is true.
The verbal forms used in this standard conform to usage described in Annex H of the ISO/IEC
Directives, Part 2. For the purposes of this standard, the auxiliary verb:
– “shall” means that compliance with a requirement or a test is mandatory for compliance
with this standard;
– “should” means that compliance with a requirement or a test is recommended but is not
mandatory for compliance with this standard;
– “may” is used to describe a permissible way to achieve compliance with a requirement or
test.
Clauses, subclauses and definitions for which a rationale is provided in informative Annex A
are marked with an asterisk (*).
A list of all parts of the IEC 60601 series, published under the general title: Medical electrical
equipment, can be found on the IEC website.

INTRODUCTION
Medical practice is increasingly using MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL
SYSTEMS for monitoring, treatment or diagnosis of PATIENTS in the EMERGENCY MEDICAL
SERVICES ENVIRONMENT (see 3.1). The safety of MEDICAL ELECTRICAL EQUIPMENT in this
uncontrolled, rough environment is a cause for concern.
This collateral standard was developed with contributions from clinicians, engineers and
regulators. The terminology, requirements, general recommendations and guidance of this
collateral standard are intended to be useful for MANUFACTURERS of MEDICAL ELECTRICAL
EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS and for technical committees responsible for the
development of particular standards.

MEDICAL ELECTRICAL EQUIPMENT –

Part 1-12: General requirements for basic
safety and essential performance –
Collateral Standard: Requirements for medical electrical
equipment and medical electrical systems intended for use
in the emergency medical services environment



1 Scope, object and related standards
1.1 * Scope
This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of
MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS, hereafter referred to as
ME EQUIPMENT and ME SYSTEMS, which are intended, as indicated in the instructions for use by
MANUFACTURER, for use in the EMS ENVIRONMENT (EMERGENCY MEDICAL SERVICES
their
ENVIRONMENT), as defined in 3.1.
NOTE 1 For the purposes of this standard, the intent of the MANUFACTURER is indicated in the instructions for use.
The RESPONSIBLE ORGANIZATION and the OPERATOR need to be aware that any other use outside the
MANUFACTURER’S INTENDED USE can result in a HAZARDOUS SITUATION for the PATIENT.
The EMS ENVIRONMENT includes
– responding to and providing life support at the scene of an emergency to a PATIENT
reported as experiencing injury or illness in a pre-hospital setting, and transporting the
PATIENT, while continuing such life support care, to an appropriate professional healthcare
facility for further care.
– providing monitoring, treatment or diagnosis during transport between professional
healthcare facilities.
This International Standard does not apply to ME EQUIPMENT and ME SYSTEMS intended solely
for use in the HOME HEALTHCARE ENVIRONMENT covered by IEC 60601-1-11 or solely for use in
professional healthcare facilities covered by IEC 60601-1 without the additions of
IEC 60601-1-11 or this collateral standard. ME EQUIPMENT and ME SYSTEMS are often not solely
intended for one environment. Such ME EQUIPMENT or ME SYSTEM can be intended for multiple
use environments, and as such, if also intended for use in the EMS ENVIRONMENT, are within
the scope of this standard.
EXAMPLE ME EQUIPMENT or ME SYSTEM intended for both the EMS ENVIRONMENT and the professional healthcare
facility environment.
NOTE 2 EMS ENVIRONMENT ME EQUIPMENT and ME SYSTEMS can be used in locations with unreliable electrical
sources and outdoor environmental conditions.
1.2 * Object
The object of this collateral standard is to provide general requirements for ME EQUIPMENT and
ME SYSTEMS carried to the scene of an emergency and used there, as well as in transport, in
situations where the ambient conditions differ from indoor conditions.
The object of this collateral standard is to specify general requirements that are in addition to
those of the general standard and to serve as the basis for particular standards.
