V-7: Standard Method of Determining Cylinder Valve Outlet Connections for Industrial Gas Mixtures

Abstract

This standard applies to the selection of a suitable cylinder valve outlet connection for industrial, specialty, and semiconductor gas mixtures for pressures up to 3000 psi at 70 °F (20 680 kPa at 21.1 °C). It applies to cylinders filled for individual use, cylinders filled individually for the purpose of assembling into a cylinder bundle, and for all cylinder bundle manifold outlet connections.

This standard does not apply to cylinders contained within an assembled cylinder bundle filled as one individual unit by use of the cylinder bundle manifold outlet connections. It also does not apply to medical gas mixtures (see CGA V-7.1).

For the assignment of ultra high integrity service (UHIS) connections for mixtures, see Appendix A. Appendix A is reproduced with permission from International Organization for Standardization (ISO) 10692-1:2001.

For the purpose of this standard, a mixture is understood to be the purposeful combination of two or more components. An odorant shall be considered a component when added to either a pure gas or a mixture. Blanketing of a pure gas or mixture is not considered the generation of a new mixture. However, the effect of the pressure increase needs to be considered when determining the FTSC code.
