This publication describes the specification requirements for air including atmospheric air and air synthesized by blending oxygen and nitrogen in the proper proportions. Atmospheric air contains a large variety of trace constituents. It is impractical to set individual limits for many of these; however, this specification qualifies certain grades of air by limiting the concentrations of specific trace constituents.

NOTE—This publication does not attempt to recommend or establish end usage designations for specific types or grades of products. It is suggested that users requiring this kind of information contact individual gas suppliers.
