This publication documents the minimum requirements for the safe preparation of compressed oxidant-fuel gas mixtures in cylinders by static methods (addition of one component after another in cylinders). This publication specifically addresses:

• key principles for compressed oxidant-fuel gas mixture manufacture;
• manufacturing feasibility studies;
• gas mixing equipment, filling, and analysis; and
• audit of oxidant-fuel gas mixture manufacturing procedures and operations.

This publication specifically describes the manufacture of compressed oxidant-fuel gas mixtures under the conditions of gas temperatures and pressures detailed within this publication. The manufacture of liquefied and liquid oxidant-fuel gas mixtures and the manufacture of compressed oxidant-fuel gas mixture by dynamic methods (filling into the cylinder by blending the components dynamically at calculated flowrates) are outside of the scope of this publication.

This publication shall be used in conjunction with the information and principles contained in CGA P-36, The Safe Preparation of Gas Mixtures [1].
