CAN/CSA-Z8835-2-01 (R2006)

International Standard ISO 8835-2:1999 has been adopted with Canadian deviations as CSA Standard CAN/CSA-Z8835-2-01. 1 Scope This part of ISO 8835 specifies requirements for inhalational anaesthetic breathing systems for adults which are supplied either assembled by the manufacturer or for assembly by the user in accordance with the manufacturer's instructions. It also covers circle absorber assemblies, exhaust valves, inspiratory and expiratory valves and, in some designs, those parts of an anaesthetic breathing system that are incorporated within an anaesthetic workstation, including the expiratory gas pathway of an anaesthetic ventilator and any parts of a non-operator-detachable anaesthetic-gas scavenging system (AGSS). This part of ISO 8835 does not cover the performance of breathing systems regarding the elimination of expired carbon dioxide, since this is complex and depends on the interaction of the patient, the fresh-gas flow, the carbon dioxide absorbent and the breathing system itself.
