Specifies non-interchangeable connections for large medical oxygen and nitrous oxide cylinders to comply with AS 2473. For medical oxygen contained in cylinders greater than 5 kg water capacity, Types 10 and 10.5 connections will be used; for all other medical gas cylinders pin-indexed outlet connections are to be used. As the diversity of demands are exhausted for single-pin indexing, double-row pin indexing will be introduced. This Standard introduces pin-indexed connections for all medical nitrous oxide connections, in order to prevent the potentially dangerous connection of industrial carbon dioxide to medical nitrous oxide applications.

This standard specified inlet threads, outlet non-interchangeability features, material, testing, and marking requirements for medical gas cylinder valves.NOTE: Although medical gases may also be used for non-medical breathing application, it is not intended that valves specified in this standard be mandatory for non-medical applications.
