manifold piping, pressure gage(s), two master flow control and shutoff valves, and two final

outlet fittings.

3.9.2 Design and construction. The manifold assembly shall be designed and

constructed to handle helium gas without leakage during cylinder filling or discharging

operations and under the mobile operating and environmental conditions specified herein.

3.9.3 Manifold materials. The manifold assembly shall be constructed of corrosion-

resistant material with high impact resistance, such as copper or brass. Manifold piping, fittings,

and attachments shall be fabricated from materials that are chemically compatible with each

other or basically the same type material.

3.9.4 Manifold piping. The manifold piping shall consist of the manifold header plus a
