Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 8835-5 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,
Subcommittee SC 1, Breathing attachments and anaesthetic machines.
ISO 8835 consists of the following parts, under the general title Inhalational anaesthesia systems:
 Part 2: Anaesthetic breathing systems for adults
 Part 3: Anaesthetic gas scavenging systems — Transfer and receiving systems
 Part 4: Anaesthetic vapour delivery devices
 Part 5: Anaesthetic ventilators
NOTE ISO 8835-1, Medical electrical equipment — Part 1: Particular requirements for the safety of anaesthetic
workstations, was withdrawn in 1998 and replaced by the second edition of IEC 60601-2-13, Medical electrical
equipment — Part 2-13: Particular requirements for the safety and essential performance of anaesthetic systems.

ISO 8835-5:2004(E)
Introduction
This part of ISO 8835 is a Particular Standard based on IEC 60601-1:1988, including Amendments 1 (1991)
and 2 (1995), hereafter referred to as the General Standard. The General Standard 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.
The General Standard 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 60601-1:1988, 1.5 and A.2,
respectively.
To facilitate the use of this part of ISO 8835, the following drafting conventions have been applied.
This part of ISO 8835 uses the same main clause titles and numbering as the General Standard, for ease of
cross-referencing of the requirements. The changes to the text of the General Standard, as supplemented by
the Collateral Standards, are specified by the use of the following words.
 “Replacement” means that the indicated clause or subclause of the General Standard is replaced
completely by the text of this Particular Standard.
 “Addition” means that the relevant text of this Particular Standard is a new element (e.g. subclause, list
item, Note, table, figure) additional to the General Standard.
 “Amendment” means that an existing element of the General Standard is partially modified by deletion
and/or addition as indicated by the text of this Particular Standard.
To avoid confusion with any amendments to the General Standard itself, a particular numbering has been
employed for elements added by this part of ISO 8835: subclauses, tables and figures are numbered starting
from 101; additional list items are lettered aa), bb), etc. and additional annexes are lettered AA, BB, etc.
In this part of ISO 8835, the following print types are used:
 requirements, compliance with which can be verified, and definitions: roman type;
 notes and examples: smaller roman type;
 description of type of document change, and test methods: italic type;
 terms defined in the General Standard IEC 60601-1:1988, Clause 2 and terms defined in this part of
ISO 8835: bold type.
Throughout this part of ISO 8835, text for which a rationale is provided in Annex AA is indicated by an asterisk

Part 5:
Anaesthetic ventilators
1 Scope
IEC 60601-1:1988, Clause 1 applies except as follows:
This part of ISO 8835 specifies particular requirements for the essential performance of anaesthetic
ventilators (as defined in 3.1). This part of ISO 8835 is applicable to anaesthetic ventilators which are
always a component of an anaesthetic system and are intended to be continuously attended by an operator.
This part of ISO 8835 is not applicable to anaesthetic ventilators intended for use with flammable
anaesthetics, as determined by Annex BB.
The requirements of this part of ISO 8835 which replace or modify the requirements of IEC 60601-1:1988 and
its Amendments 1 (1991) and 2 (1995) are intended to take precedence over the corresponding general
requirements.
