DIN Standards Committee Pressurized Gas Installations

Overview

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).
