CGA PS-22

USP is in the process of modifying the monographs for medical gases. CGA PS-22 defines the basic industry practices that will enable a medical gas manufacturer to be in compliance with FDA regulations during modifications to the USP/NF monographs.

This position statement sets forth acceptable industry test practices for products manufactured at ASU and cylinder filling operations. It also establishes the use of industry-produced reference standards that are NIST traceable as an acceptable practice.
