The sulphur content and hydrogen sulphide content shall be determined by
approved standard methods generally in use in the natural gas industry.
The hydrogen content shall be determined by the method prescribed by
the Natural Gasoline Processors Association of America in NGPA Publication
2261-72 or ASTM publication D 194564 (1968) or any revisions thereof, or by
such other method as shall be mutually agreed upon.
The Btu content shall be determined by joint tests made by taking
samples of the gas and determining the Btu content by means of a method or
methods agreed upon. If a recording calorimeter is installed, the monthly
average of the daily readings obtained shall be used. Btu values shall be
corrected to 14.73 pounds per square inch absolute at 60oF. saturated with
The water vapor content shall be determined at such intervals as shall
be found necessary in practice, by the use of dew point apparatus approved
by the Bureau of Mines and utilizing curves for "Water Vapor Content of
Compressed Natural Gas" comprising Figure 41 to Bureau of Mines, U. S.
Department of the Interior, Monograph 8 "Gas Hydrates and Their Relation to
the Operation of Natural-Gas Pipe Lines," or by such other curve or method
as shall be mutually agreed upon.
