Description

This standard specifies requirements for regulators used with compressed gases to reduce the supply pressure from a storage cylinder, pipeline, or other source to the use pressure.

This standard contains design and manufacturing requirements relating to materials, construction, perfor-mance, test procedures, information, marking, and packaging of pressure regulators. Appendix A provides information relating to regulator flow capacity calculations. For pressure regulators used with medical gases, additional requirements are specified in CGA E-7, Medical Gas Pressure Regulators, Flowmeters, and Orifice Flow Selectors [1].

This standard does not apply to liquefied petroleum gas pressure regulators for equipment intended for installation and use in accordance with the requirements of NFPA 58, Liquefied Petroleum Gas Code [2].
