BS EN ISO 8835-4:2009 Inhalational anaesthesia systems. Anaesthetic vapour delivery devices BS EN ISO 8835 consists of the following parts, under the general title Inhalational anaesthesia systems:

Part 2: Anaesthetic breathing systems for adults
Part 3: Anaesthetic gas scavenging systems. Transfer and receiving systems
Part 4: Anaesthetic vapour delivery devices
Part 5: Anaesthetic ventilators

BS EN ISO 8835-4 specifies particular requirements for the essential performance of anaesthetic vapour delivery devices (AVDDs). This international standard is applicable to AVDDs which are a component of an anaesthetic system and are intended to be continuously operator-attended. Part 4 of BS EN ISO 8835 gives specific requirements for AVDDs which are supplementary to the applicable general requirements in IEC 60601-2-13 . BS EN ISO 8835-4 is not applicable to AVDDs intended for use with flammable anaesthetics, as determined by Annex CC, and AVDDs intended for use within anaesthetic breathing systems (e.g. draw-over vaporizers). The requirements of this part of ISO 8835 which replace or modify the requirements of IEC 60601-1:1988 and its Amendments 1 (1991) and 2 (1995) are intended to take precedence over the corresponding general requirements.
