What Does CGA Stand for?

CGA stands for the Compressed Gas Association. 

Since 1913, the Compressed Gas Association has been dedicated to the development and promotion of safety standards and safe practices in the industrial gas industry. More than 125 member companies worldwide work together through the committee system to create technical specifications, safety standards, and training and educational materials; to cooperate with governmental agencies in formulating responsible regulations and standards; and to promote compliance with these regulations and standards in the workplace.

They represent all facets of the industry; manufacturers, distributors, suppliers, and transporters of gases, cryogenic liquids, and related products. CGA's sphere of influence encompasses industrial, medical, and specialty gases in compressed or liquefied form, and a range of gas handling equipment. The work of CGA is carried out by committees of volunteers from member companies having expertise in the particular areas targeted. Each of these committees focuses on work item projects through its subcommittees and task forces. These working groups meet regularly at CGA headquarters in Northern Virginia or at other sites around the U.S. and Canada. CGA's staff provides coordination and technical support.


What Does DISS Stand For?

DISS stands for Diameter Index Safety System. The Compressed Gas Association (CGA) developed the diameter Index Safety System (DISS) to establish a standard for non-interchangeable removable connections for use in Medical gases (200 psi max.), Vacuum (Suction) and Evacuation Service. Each DISS connection consists of a Body adaptor, Nipple, and Nut. The DISS system is utilized on gas pressure regulators outlets, wall outlets, anesthesia equipment and respiratory equipment.


What Does PISS Stand For?

PISS stands for Pin Index System, a system for identifying connectors for certain small cylinders of medical gases that have flush valve outlets rather than threaded outlets. The identifying code consists of a specific combination of two holes in the face of the valve into which connecting pins for a particular type of gas must fit in perfect alignment. For example, the index hole position for a cylinder of oxygen is 2-5, for nitrous oxide it is 3-5, and so on.
