Draft Scope/Description:

The Canadian Deviations are to replace the terms “female” and “male” when referring to connectors in the ISO standard, as a member flagged this when we last reaffirmed the second edition. As well as adopting the 2019 AMD 1 that provides additional content.

This part of ISO 5356 specifies dimensional requirements for screw-threaded weight-bearing conical connectors intended for use with inhalation anaesthesia apparatus and ventilators. Such connectors are intended for mounting heavy accessories.


This part of ISO 5356 specifies requirements for the following screw-threaded, weight-bearing conical connectors:
— 22 mm connectors;
— 22 mm/15 mm coaxial connectors.


Requirements for the application of screw-threaded, weight-bearing conical connectors 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 on cones and sockets are specified in ISO 5356-1.
