FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60601-2-13 has been developed by a Joint Working Group
consisting of IEC/SC 62D, Electromedical equipment, of IEC technical committee 62:
Electrical equipment in medical practice, and ISO TC 121/SC 1, Breathing attachments and
anaesthetic machines.
It is published as double logo standard.
This third edition cancels and replaces the second edition published in 1998. This edition
constitutes a technical revision.
The text of this Particular Standard is based on the following documents:
FDIS Report on voting
62D/475/FDIS 62D/476/RVD
Full information on the voting for the approval of this Particular Standard can be found in the
report on voting indicated in the above table. In ISO, the standard has been approved by 13
P-members out of 13 having cast a vote.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
In this Particular Standard, the following print types are used:

INTRODUCTION
In response to requests for harmonization between the current European and International
standards for anaesthetic workstations this standard has been developed by the
IEC/ISO Joint Working Group to specify requirements for ANAESTHETIC SYSTEMS supplied
complete, as well as requirements for individual devices which are intended to be part of an
ANAESTHETIC SYSTEM. It applies in conjunction with IEC 60601-1:1988 (Including all
amendments) hereafter referred to as the General Standard. As stated in 1.3 of
IEC 60601-1-1988, the requirements in this standard take priority over those of the General
Standard.
This standard has been structured to allow USERS to configure an ANAESTHETIC SYSTEM in
conformance with professional guidelines and to meet the needs of their clinical practice.
In order to achieve this aim, the standard identifies particular requirements pertinent to
specific devices, and to their associated MONITORING DEVICE(S), ALARM SYSTEM(s) and
PROTECTION DEVICE(S), and defines the interfaces. This standard also specifies requirements
for optional devices, together with their respective MONITORING DEVICE(S), ALARM SYSTEM(S)
and PROTECTION DEVICE(S).
The indicated requirements are followed by specifications for the relevant tests. An asterisk
(*) denotes clauses for which there is a rationale comment in Annex AA. It is considered that
knowledge of the reasons for these requirements will facilitate the proper application of the
standard and be of use in any revision that may be necessitated by changes in clinical
practice or as a result of developments in technology.
NOTE The decimal separator for all numeric values is "," (comma).
The following graphic representation of the structure of this standard is being provided for
informational purposes only.

The clauses and subclauses of this section of the General Standard apply except as follows:
1 Scope and object
This clause of the General Standard applies except as follows:
1.1 Scope
Addition
This Particular Standard specifies safety and essential performance requirements for an
ANAESTHETIC SYSTEM (as defined in 2.101.7) as well as individual devices designed for use in
an ANAESTHETIC SYSTEM.
This Particular Standard does not apply to:
– ANAESTHETIC SYSTEM(S) intended for use with flammable anaesthetic agents, as
determined by Annex DD,
– portable ANAESTHETIC SYSTEM(S) for use in remote sites, open fields for rescue operations
or in disaster areas,
– dental analgesia apparatus.
1.2 Object
Replacement:
The object of this Particular Standard is to specify particular safety and essential performance
requirements for individual devices designed for use in an ANAESTHETIC SYSTEM as well as
specific requirements for the ANAESTHETIC GAS DELIVERY SYSTEM. This standard specifies
requirements and defines interfaces for:
– individual devices designed for use in an ANAESTHETIC SYSTEM(S), and
– integrated ANAESTHETIC SYSTEMS.
1.3 Particular Standards
This Particular Standard amends and supplements a set of IEC publications consisting of
IEC 60601-1:1988, Medical electrical equipment – Part 1: General requirements for safety,
its amendment 1 (1991) and amendment 2 (1995), hereinafter referred to as the “General
Standard”.
The General Standard takes into account IEC 60601-1-1:2000, Medical electrical equipment –
Part 1-1: General requirements for safety – Collateral standard: Safety requirements for
medical electrical systems and IEC 60601-1-2 2001, Medical electrical equipment – Part 1-2:
General requirements for safety – Collateral standard: Electromagnetic compatibility –
Requirements and tests.
– 8 – 60601-2-13  IEC:2003(E)
The numbering of sections, clauses and subclauses of this Particular Standard corresponds
with that of the General Standard. 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 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.
“Amendment” means that the clause or subclause of the General Standard is amended as
indicated by the text of this Particular Standard.
Subclauses or figures which are additional to those of the General Standard are numbered
starting from 101, additional annexes are lettered AA, BB, etc., and additional items aa), bb),
etc.
The term "this standard" covers this Particular Standard, used together with the General
Standard and the Collateral Standards.
Where there is no corresponding section, clause or subclause in this Particular Standard, the
section, clause or subclause of the General Standard, although possibly not relevant, applies
without modification.
Where it is intended that any part of the General Standard, although possibly relevant, is not
to be applied, a statement to that effect is given in this Particular Standard.
The requirements of this Particular Standard replacing or modifying requirements of the
General Standard or a Collateral Standard take precedence over the corresponding general
requirement(s).
