scope:

This 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 callibration of anaesthetic agent vaporizers are outside the scope of this International standard. Anaesthetic gases adressed in this standard include, but are not limited to, halothane, enflurane, isoflurane, sevoflurane, desflurane and nitrous oxide.
