CSA Preface This is the second edition of CAN/CSA-ISO 5356-1, Anaesthetic and respiratory equipment — Conical connectors — Part 1: Cones and sockets , which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 5356-1 (fourth edition, 2015-03-15). It supersedes the previous edition published in 2008 as CAN/CSA-Z5356-1 (adopted ISO 5356-1:2004, with Canadian deviations). For brevity, this Standard will be referred to as “CAN/CSA-ISO 5356-1” throughout. This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Perioperative Safety, under the jurisdiction of the CSA Strategic Steering Committee on Health Care Technology & Systems, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This part of ISO 5356 specifies dimensional and gauging requirements for cones and sockets intended for connecting anaesthetic and respiratory equipment, e.g. in breathing systems, anaesthetic gas scavenging systems, and vaporizers. The cones and sockets are therefore not regarded as devices in their own right. This part of ISO 5356 gives requirements for the following cones and sockets: — 8,5 mm and 11,5 mm sizes intended for use in neonatal and paediatric breathing systems; — 15 mm and 22 mm sizes intended for general use in breathing systems; — 22 mm latching sockets (including performance requirements); — 23 mm size intended for use with vaporizers, but not for use in breathing systems; — 30 mm size intended for the connection of a breathing system to an anaesthetic gas scavenging system. This part of ISO 5356 does not specify the medical devices and accessories on which these cones and sockets are to be provided. Requirements for the application of cones and sockets are not included in this part of ISO 5356, but are or will be given in the relevant International Standards for specific medical devices and accessories. NOTE Requirements for screw-threaded weight-bearing connectors are specified in ISO 5356-2.
