This International Standard specifies the characteristics of outlet connections for gas cylinder valves for compressed breathable air gas cylinders. It states the fundamental requirements for both; the connection and its components and includes basic dimensions. Included in this International Standard are the following connections: - yoke type outlet connection for SCUBA use up to a maximum cylinder working pressure of 232 bar; - threaded type outlet connections up to a maximum cylinder working pressure of 232 bar and 300 bar; and - threaded type outlet connection for SCUBA use up to a maximum cylinder working pressure of 232 bar including adaptor for users to convert into a yoke type outlet.
