These requirements are for stationary cylinder discharging manifolds for compressed gases for industrial use. Manifolds are used to connect compressed gas cylinders together to supply a distribution system with a particular gas at a selected distribution pressure. The requirements cover manifolds complete to the point where they connect to a distribution system.

Three basic gas groupings are covered:
  • Fuel gases (grouped as acetylene, liquefied fuel gases, and nonliquefied fuel gases) - maximum 3000 psi (20 684 kPa) at 70 °F (21.1 °C);
  • Oxygen and air - maximum 3000 psi (20 684 kPa) at 70 °F (21.1 °C); and
  • Carbon dioxide, nitrogen, and inert gases - maximum 3000 psi (20 684 kPa) at 70 °F (21.1 °C).
This publication does not cover manifolds for medical gas cylinders, for charging cylinders, or for gas or liquid withdrawal from portable cryogenic containers (DOT 4L/TC-4LM).
