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 cooperation 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 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. IEC shall not be held responsible for identifying any such patent rights.
International Standard IEC 60601-2-12 has been prepared by subcommittee 62D: Electro-
medical equipment, of IEC technical committee 62: Electrical equipment in medical practice.
ISO TC 121/SC 3, Lung ventilators and related equipment, also participated in the preparation
of this standard.
This second edition replaces the first edition of IEC 60601-2-12:1988, Medical electrical
equipment – Part 2: Particular requirements for the safety of lung ventilators for medical use,
and ISO 10651-1:1993, Lung ventilators for medical use – Part 1: Requirements.
The text of this Particular Standard is based on the following documents:
FDIS Report on voting
62D/414/FDIS 62D/440/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annex BB forms an integral part of this standard.
Annexes AA and CC are for information only.

INTRODUCTION
Critical care VENTILATORS are an essential medical device in every intensive care unit (ICU).
Approximately half of all PATIENTS in ICUs receive partial to full ventilatory support with this
EQUIPMENT. Given the vulnerable status of these PATIENTS, EQUIPMENT safety is of fundamental
importance. Accordingly, this Particular Standard, by building on other standards and
specifically on IEC 60601-1: Medical electrical equipment – Part 1: General requirements for
safety, herein referred to as the “General Standard”, sets the minimum requirements that
should be met by every critical care VENTILATOR that is designed after the publication of this
Particular Standard.
A rationale for the most important requirements is given in Annex AA.
Continuous positive airway pressure (CPAP) devices, sleep apnea therapy devices, support-
care VENTILATORs, anaesthesia, emergency and transport VENTILATORs, jet and high frequency
VENTILATOR and oscillators are not covered by this Particular Standard, nor are devices that
may be used within hospitals, intended solely to augment the ventilation of spontaneously
breathing PATIENTS.

SECTION ONE – GENERAL
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 the safety requirements for VENTILATORS, as defined in
2.1.125, intended for use in critical care settings.
Continuous positive airway pressure (CPAP) devices, sleep apnea therapy devices, support-
care VENTILATORs, emergency and transport VENTILATORs, jet and high frequency VENTILATORs
and oscillators are outside the scope of this Particular Standard, nor are devices that may be
used within hospitals, intended solely to augment the ventilation of spontaneously breathing
PATIENTS. Standards for other types of VENTILATORs, e.g. high frequency jet and oscillation
ventilators, are under consideration.
Requirements for VENTILATORs intended for anaesthetic applications are given in IEC 60601-2-13.
1.2 Object
Addition:
The object of this standard is to specify particular safety requirements for VENTILATORS
intended for use in critical care settings.
1.3 Particular standards
Addition:
This Particular Standard refers to IEC 60601-1:1988, Medical electrical equipment – Part 1:
General requirements for safety, as amended by its amendment 1 (1991) and its amendment 2
(1995), herein referred to as the “General Standard”.
