1.1 These requirements cover indicating pressure gauges of the elastic element type usually employed in the high-pressure side of regulators or reducing valves used on compressed gas containers or cylinders of oxygen, hydrogen, nitrogen, and other gases. Such gauges usually have pressure ranges of 0 – 1500, 0 – 2000, 0 – 3000, 0 – 4000, 0 – 5000, or 0 – 6000 pounds per square inch (psi) (0 – 10.34, 0 – 13.78, 0 – 20.68, 0 – 27.56, 0 – 34.47, or 0 – 41.36 MPa).
