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 8835-2 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,
Subcommittee SC 1, Breathing attachments and anaesthetic machines.
This third edition cancels and replaces the second edition (ISO 8835-2:1999), which has been technically
revised.
ISO 8835 consists of the following parts, under the general title Inhalational anaesthesia systems:
⎯ Part 2: Anaesthetic breathing systems
⎯ Part 3: Transfer and receiving systems of active anaesthetic gas scavenging systems
⎯ Part 4: Anaesthetic vapour delivery devices
⎯ Part 5: Anaesthetic ventilators

Introduction
An anaesthetic breathing system comprises an assembly of tubes and connectors and may include valves, a
reservoir bag and a circle absorber assembly. Other items of equipment (e.g. humidifiers, filters, spirometers,
thermometers, gas analysers) may be incorporated into an anaesthetic breathing system.
Its function is to convey mixtures of gases to and from the patient.
Annex A gives typical test arrangements and methods. Annex B gives the rationale for some of the
requirements found within this part of ISO 8835.
Annex B contains rationale statements for some of the requirements of this part of ISO 8835. The clauses and
subclauses marked with an asterix (*) before their number have corresponding rationale contained in Annex B,
included to provide additional insight into the reasoning that led to the requirements and recommendations
that have been incorporated in this International Standard.
Annex C lists the clauses of this part of ISO 8835 that address the environmental aspects of the device.

INTERNATIONAL STANDARD ISO 8835-2:2007(E)

Inhalational anaesthesia systems —
Part 2:
Anaesthetic breathing systems
* 1 Scope
This part of ISO 8835 specifies requirements for anaesthetic breathing systems that are supplied either
assembled by the manufacturer or for assembly by the user in accordance with the manufacturer's
instructions.
It also covers circle absorber assemblies, exhaust valves, inspiratory and expiratory valves and, in some
designs, those parts of an anaesthetic breathing system that are incorporated within an inhalation anaesthetic
system, including the expiratory gas pathway of an anaesthetic ventilator.
This part of ISO 8835 does not cover the performance of anaesthetic breathing systems regarding the
elimination of expired carbon dioxide since this is complex and depends on the interaction of the patient, the
fresh gas flow, the carbon dioxide absorbent and the anaesthetic breathing system itself.
This part of ISO 8835 does not apply to anaesthetic breathing systems intended for use with flammable
anaesthetic agents/gases as determined by Annex DD of IEC 60601-2-13:2003.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 4135 and IEC 60601-2-13 and the
following apply.
3.1
anaesthetic breathing system
ABS
those inspiratory and expiratory pathways through which gas flows at respiratory pressure between the fresh
gas inlet (3.6), the patient connection port (3.9) and the exhaust valve (3.5) or exhaust port (3.4)
3.2
circle absorber assembly
that part of a circle breathing system (3.3) which comprises one or more carbon-dioxide-absorbent
containers, inspiratory and expiratory valves or other means of ensuring unidirectional gas flow, two ports for
connection to breathing tubes, a fresh gas inlet (3.6), a reservoir bag port and/or an anaesthetic ventilator
port
3.3
circle breathing system
anaesthetic breathing system (3.1) in which the direction of gas flow through inspiratory and expiratory
pathways is unidirectional and in which the two pathways form a circle
3.4
exhaust port
that port through which waste gas(es) are discharged to the atmosphere or to an anaesthetic gas scavenging
system (AGSS)
3.5
exhaust valve
valve through which waste gas(es) are discharged to the atmosphere or to an AGSS

4 General
4.1 Materials
All components of an anaesthetic breathing system shall be designed and manufactured in such a way as to
reduce to a minimum the risks posed by substances leaching from them.
When selecting materials for components of anaesthetic breathing systems, manufacturers should take
particular care to ensure compatibility of the materials with the gases and anaesthetic agents with which they
are intended to come into contact.
4.2 Anaesthetic breathing system component packaging
Anaesthetic breathing system components shall be packaged in such a way as to minimize the risk of
incomplete removal of the packaging before use.
NOTE 1 This is to prevent accidental retention of the packaging (e.g. transparent wrapper, caps, lids, covers, etc.) and
to ensure its removal by the operator prior to use.
NOTE 2 Attention is drawn to IEC 60601-1-6 which requires a usability engineering process. Completion of this
process will ensure that such risks are minimized to an acceptable level.
4.3 Electrical requirements
* 4.3.1 General
If the anaesthetic breathing system incorporates electrically powered components, the system shall comply
with applicable parts of IEC 60601-1 and IEC 60601-1-2.
Anaesthetic breathing systems and anaesthetic breathing system components which incorporate RF wireless
technology should be assessed for the following risks:
⎯ electromagnetic compatibility (EMC);
⎯ performance of wireless functions;
⎯ wireless coexistence;
⎯ wireless quality of service;
⎯ integrity of data transmitted wirelessly;
⎯ security of data transmitted wirelessly;
⎯ wireless network access.
