CSA Preface

This is the second edition of CAN/CSA-Z8835-2, Inhalational anaesthesia systems - Part 2: Anaesthetic breathing systems, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 8835-2 (third edition, 2007-08-15). It supersedes the previous edition published in 2001 as CAN/CSA-Z8835-2, Inhalational anaesthesia systems - Part 2: Anaesthetic breathing systems for adults (adopted ISO 8835-2:1999).

* 1 Scope

This part of ISO 8835 specifies requirements for anaesthetic breathing systems that 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 inhalation anaesthetic system, including the expiratory gas pathway of an anaesthetic ventilator.

This part of ISO 8835 does not cover the performance of anaesthetic 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 anaesthetic breathing system itself.

This part of ISO 8835 does not apply to anaesthetic breathing systems intended for use with flammable anaesthetic agents/gases as determined by Annex DD of IEC 60601-2-13:2003.
