Part 2-27: Particular requirements for the basic safety and essential
performance of electrocardiographic monitoring equipment


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 60601-2-27 has been prepared by IEC subcommittee 62D:
Electromedical equipment of IEC technical committee 62: Electrical equipment in medical
practice.
This third edition cancels and replaces the second edition of IEC 60601-2-27 published in
2005. This edition constitutes a technical revision to the new structure of IEC 60601-1:2005
(third edition).

INTRODUCTION
This particular standard concerns the BASIC SAFETY and ESSENTIAL PERFORMANCE of
ELECTROCARDIOGRAPHIC MONITORING EQUIPMENT. It amends and supplements IEC 60601-1
(third edition, 2005): Medical electrical equipment – Part 1: General requirements for basic
safety and essential performance hereinafter referred to as the general standard.
The aim of this third edition is to bring this particular standard up to date with reference to the
third edition of the general standard through reformatting and technical changes.
The requirements of this particular standard take priority over those of the general standard.
A “General guidance and rationale” for the more important requirements of this particular
standard is included in Annex AA. It is considered that knowledge of the reasons for these
requirements will not only facilitate the proper application of the standard but will, in due
course, expedite any revision necessitated by changes in clinical practice or as a result of
developments in technology. However, Annex AA does not form part of the requirements of
this standard.

201.1.4 Particular standards
Replacement:
In the IEC 60601 series, particular standards may modify, replace or delete requirements
contained in the general standard and collateral standards as appropriate for the particular
ME EQUIPMENT under consideration, and may add other BASIC SAFETY and ESSENTIAL
PERFORMANCE requirements.
A requirement of a particular standard takes priority over the general standard.
For brevity, IEC 60601-1 is referred to in this particular standard as the general standard.
Collateral standards are referred to by their document number.
The numbering of clauses and subclauses of this particular standard corresponds to that of
the general standard with the prefix “201” (e.g. 201.1 in this standard addresses the content
of Clause 1 of the general standard) or applicable collateral standard with the prefix “20x”
where x is the final digit(s) of the collateral standard document number (e.g. 202.4 in this
particular standard addresses the content of Clause 4 of the IEC 60601-1-2 collateral
standard, 203.4 in this particular standard addresses the content of Clause 4 of the
IEC 60601-1-3 collateral standard, etc.). The changes to the text of the general standard are
specified by the use of the following words:
“Replacement” means that the clause or subclause of the general standard or applicable
collateral standard is replaced completely by the text of this particular standard.
“Addition” means that the text of this particular standard is additional to the requirements of
the general standard
