DIN EN ISO 12209:2017-05

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, 300 bar and 500 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. Annex A gives the outlet connection type test procedures. Requirements for cylinder valves (see ISO 10297) are not covered by this International Standard. Requirements for material specifications and gas/material compatibility (see ISO 11114-1 and ISO 11114-2) are not covered by this International Standard. This standard differs from DIN EN ISO 12209:2013-12 as follows: a) threaded type outlet connections up to a maximum cylinder working pressure of 500 bar have been included; b) the dimensions of the 232 bar filling connector and a gas withdrawal connector have been amended; c) the dimensions of the 300 bar filling connector and a gas withdrawal connector have been amended; d) the contents of Amendment 1 have been included. The responsible German standardization committee is Working Committee NA 016-00-03 AA "Druckgasflaschen und Ausrüstung; Spiegelausschuss zu CEN/TC 23 und ISO/TC 58" ("Transportable gas cylinders and equipment; National mirror committee to CEN/TC 23 and ISO/TC 58") at DIN Standards Committee Pressurized Gas Installations (NDG).
