pounds per million standard cubic feet.

delivered shall not exceed twenty degrees Fahrenheit (20øF) at a pressure
of 600 psig.
11.4 Total Sulfur. The gas shall not contain more than three-
quarters (0.75) grain of total sulfur per one hundred (100) standard cubic
feet, which includes hydrogen sulfide, carbonyl sulfide, carbon disulfide,
mercaptans, and mono-, di- and poly-sulfides. The gas shall also meet the
following individual specifications for hydrogen sulfide, mercaptan sulfur

(c) Organic Sulfur. The organic sulfur content shall not
exceed five-tenths (0.5) grain per one hundred (100) standard cubic feet,
which includes mercaptans, mono-, di- and poly-sulfides, but it does not
include hydrogen sulfide, carbonyl sulfide or carbon disulfide.
11.5 Oxygen. The oxygen content shall not exceed two-tenths of one
percent (0.2%) by volume and every reasonable effort shall be made to keep
the gas delivered free of oxygen.
