Defines requirements for anaesthetic gas monitors to be used in determination of the anaesthetic vapour and/or gas level(s) in breathing gas mixtures. Covers both diverting and non-diverting gas monitors, whichever measuring technology is used. Includes anaesthetic gas mixtures identifying monitors, and monitoring of patient breathing mixtures, output of anaesthesia workstations, output of vaporizers in addition to anaesthesia ventilators and breathing systems. Does not cover anaesthetic gas monitors for laboratory research, non-human use or for calibrating anaesthetic agent vaporizers.
