CGA Standards

What is CGA?

Founded in 1913, the Compressed Gas Association is dedicated to the development and promotion of safety standards in the industrial, medical, and food gases industry.

CGA publications address a wide range of standards, technical information and recommendations for best practices in the manufacture, storage, transportation, distribution, and use of industrial gases, cryogenic liquids and other products, including gas-handling equipment.

From industrial gases used in welding and metal fabrication, to medical gases used in hospitals and clinics, CGA members are dedicated to ensuring that these gases are handled safely and responsibly. With over 100 years of industry experience, CGA is the go-to resource for regulators, policymakers, and gas industry professionals looking for guidance on the safe production, transportation, and use of compressed gases.

CGA Standards

CGA maintains a library of over 350 publications, safety alerts, safety bulletins, technical bulletins, technical reports, training materials, and our Handbook of Compressed Gases. CGA’s positions address safety and technical information related to the manufacture, transportation, storage, transfilling, and disposal of gases (liquefied, non-liquefied, dissolved, and cryogenic); and the containers and valve which hold compressed gases.

Gain easy access to CGA standards with ASTM Compass. With up-to-date standards available anytime and anywhere with an internet connection, you can save valuable time and resources. Compass provides you one of the most comprehensive libraries of technical information available in the world including offering easy navigation through CGA’s extensive collection of standards.

With the ability to download and print PDF standards, you can work even when offline. Experience streamlined workflow and quick access to the information you need with the power of ASTM Compass.
