Specifies requirements for the outlet connections for gas cylinders containing medical gases and certain related and manufacturing features of the valve.

This Standard specifies the outlet connections for gas cylinders containing medical gases. Additionally, it specifies certain related design and manufacturing features of the valve. It includes the following:(a) Outlet connections to be used with nominated medical gases.(b) Basic dimensions for pin-indexed yoke connections.(c) Design of the pin-indexed yoke. (d) Dimensions and positions of the holes and pins for the valve and yoke. (e) Requirements for cylinder valves to be fitted to medical gas cylinders, including working pressures and certain design and manufacturing features.WARNING: THE CONTENTS OF A GAS CYLINDER ARE IDENTIFIED PRIMARILY BY MARKING AND LABELLING ON THE CYLINDER. CYLINDER COLOURS ARE USED AS A SECONDARY MEANS OF IDENTIFICATION. LABELS AND MARKINGS ON A GAS CYLINDER SHOULD ALWAYS BE CONSULTED PRIOR TO USE. NOTE: Correspondence between the provisions of ISO 407 and this Standard is provided in Appendix A.
