In cases where government regulation is inspecific, CGA documents are considered authoritative.
CGA falls into a group of trade associations whose publications are relied on by government.
These groups include the National Fire Protection Association (NFPA) and ASTM International.
For example, the state of Montana, the U.S. Army, and OSHA point to CGA documents for regulatory guidance.
The range of available connection standards covers the majority of the range of industrial, ultra-pure and medical gases in use, including the medical pin index safety system, scuba cylinder valves and liquefied natural gas for home use.
