Anaesthetic gas monitors (ISO 11196:1995 including Technical Corrigendum 1:1997)

NOTE1: See the rationale in annex N.  ISO 11196 is one of a series of International Standards based on IEC 601-1; in IEC 601-1 (the "General Standard"), this type of International Standard is referred to as a "Particular Standard". As stated in 1.3 of IEC 601-1:1988, the requirements of this International Standard take precedence over those of IEC 601-1.  The scope and object given in clause 1 of IEC 601-1:1998 apply except that 1.1 shall be replaced by the following:  This International Standard specifies requirements for anaesthetic gas monitors intended for use in determining the anaesthetic vapour and/or gas level(s) in breathing gas mixtures and/or fresh gas mixtures. Both diverting and non-diverting anaesthetic gas  monitors are covered, irrespective of the measuring technology used. Also included are anaesthetic gas identifying monitors. The field of application includes monitoring patient breathing mixtures, the output of anaesthesia workstations, and the output of vaporizers as well as anaesthesia ventilators and breathing systems.  Anaesthetic gas monitors intended for use in laboratory research, non-human applications or for calibration of anaesthetic agent vaporizers are outside the scope of this International Standard.  Anaesthetic gases addressed in this International Standard include, but are not limited to, halothane, enflurane, isoflurane, sevoflurane, desflurane and nitrous oxide.

ANMERKUNG 1: Siehe Begründung in Anhang N. ISO 11196 ist Teil einer Internationaler Normenreihe, die auf IEC 601-1 basiert. In IEC 601-1 (der "Allgemeinen Festlegung") wird diese Art einer Internationalen Norm als "Besondere Fetslegung" bezeichnet. Wie in 1.3 von IEC 601-1:1988 festgestellt, haben die Anforderungen dieser Internationalen Norm Vorrang vor denen der 601-1.

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. Esch 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 patt in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
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.
International Standard ISO 1 ‘l196 was prepared by Technical Committee
ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee
SC 1, Breathing attachments and anaesthetic machines.

Introduction
The measurement of the concentration of inhalation anaesthetic gases is
becoming common practice. This International Standard establishes re-
quirements for anaesthetic gas monitors that are achievable within the
limits of existing technology.
Calibration gases (i.e. gases with accurate molar concentrations of anaes-
thetic agents) generated by gravimetric methods defined in ISO 6142 are
directly traceable to national mass Standards.
Such gases may be used
to calibrate anaesthetic gas monitors directly, or
d
b) to calibrate intermediate methods used to verify secondary calibration
gases which are then used to calibrate anaesthetic gas monitors.
For example, such intermediate methods may be the use of refractometry,
mass spectrometry, etc.
Annex N contains rationales for the most important requirements and is
included to provide additional insight for the reasoning that led to the re-
quirements and recommendations that have been incorporated in this
International Standard.

Anaesthetic gas monitors
Section 1: General
1.1 Scope
NOTE 1 See the rationale in annex N.
ISO 11196 is one of a series of International Standards based on IEC 601-1; in IEC 601-1 (the “General
Standard ”), this type of International Standard is referred to as a “Particular Standard ”. As stated in 1.3 of
IEC 601-1 :1988, the requirements of this International Standard take precedence over those of IEC 601-1.
The scope and Object given in clause 1 of IEC 601-1:1988 apply except that 1.1 shall be replaced by the following:
This International Standard specifies requirements for anaesthetic gas monitors intended for use in determining
the anaesthetic vapour and/or gas IeveI(s) in breathing gas mixtures and/or fresh gas mixtures. Both diverting and
non-diverting anaesthetic gas monitors are covered, irrespective of the measuring technology used. Also included
are anaesthetic gas identifying monitors. The field of application includes monitoring Patient breathing mixtures,
the output of anaesthesia workstations, and the output of vaporizers as well as anaesthesia Ventilators and
breathing Systems.
Anaesthetic gas monitors intended for use in laboratory research, non-human applications or for calibration of an-
aesthetic agent vaporizers are outside the scope of this International Standard.
Anaesthetic gases addressed in this International Standard include, but are not limited to, halothane, enflurane,
isoflurane, sevoflurane, desflurane and nitrous Oxide.
1.2 Normative references
The following Standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All Standards are subject to
revision, and Parties to agreements based on this International Standard are encouraged to investigate the possi-
bility of applying the most recent editions of the Standards indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.

1.3 Definitions
For the purposes of this International Standard, the definitions given in clause 2 of IEC 601-1 :1988 and ISO 4135,
and the following definitions apply.
1.3.1 alarm Set-Point: Setting of the adjustment control, or display value which indicates the anaesthetic gas
reading, at or beyond which the alarm is intended to be activated.
NOTE 2 Terms such as “alarm Iimits” or “alarm threshold” are frequently used to describe the same function.
1.3.2 alarm System: Those Parts of the anaesthetic gas monitor which
establish the alarm Set-Point(s);
a)
activate an alarm when the anaesthetic gas reading is less than or equal to the low alarm Set-Point, if provided,
b)
or is equal to or greater than the high alarm Set-Point.
1.3.3 anaesthesia workstation: System for administration of anaesthesia which includes, but is not limited to,
an anaesthetic gas delivery System, its essential monitoring devices, and essential hazard protection devices.
1.3.4 anaesthetic gas monitor: Device for the measurement of the anaesthetic gas level in anaesthetic gas
mixtures.
1.3.5 anaesthetic gas: Gas and/or vapour of a volatile agent used in anaesthesia.
1.3.6 anaesthetic gas level: Concentration in volume percent or partial pressure of anaesthetic gas in a gaseous
mixture.
1.3.7 anaesthetic gas reading: Measured anaesthetic gas level as indicated by the anaesthetic gas monitor
display.
1.3.8 applied Part: Part of the anaesthetic gas monitor intended to be connected with the Patient or with the
anaesthetic breathing system. ‘)
1.3.9 delay time: Time from a step function Change in anaesthetic gas level at the sampling site to the
achievement of IO % of the step Change in the anaesthetic gas reading of the anaesthetic gas monitor (see
figure 1).

1.4 General requirements and general requirements for tests
The requirements given in clauses 3 and 4 of IEC 601-1 :1988 apply with the following additions?
All Parts of an anaesthetic gas monitor and their devices should be designed and manufactured to minimize health
risks due to toxic products and substances leached from the devices during use.
3.6 j) Applicable Single fault conditions are:
short- and open-circuits of components or wiring which tan
a)
- Cause Sparks to occur, or
- increase the energy of Sparks, or
- increase the temperature (see section 7);
b) incorrect output resulting from Software error.
