  • SCOPE

    1 Scope

    1.1 These requirements cover equipment for manifolding high-pressure gas cylinders to supply gas for various industrial and commercial applications. Cylinders are manifolded for the purpose of centralizing the gas supply, to provide a continuous supply of gas, or to provide gas at a rate in excess of that which may be obtained from a single cylinder.

    1.2 Manifolds for services other than for nonflammable medical gases are intended to be installed and used in accordance with the Standard for the Design and Installation of Oxygen-Fuel Gas Systems for Welding, Cutting, and Allied Processes, NFPA 51. Those for nonflammable medical gases are intended to be installed and used in accordance with the Standard for Healthcare Facilities, NFPA 99.
