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 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.
