The American Welding Society's AWS C4.2, Recommended Practices for Safe Oxyfuel Gas Cutting Torch Operation, had been published.

The 62-page book describes the oxyfuel gas cutting process and latest procedures and safety requirements, using terminology compatible with ISO documents. Illustrations show torch and nozzle configurations, and examples of production-cut surfaces. The standard uses both U.S. Customary Units and the International System of Units.
