(b) Shall not contain more than one grain of hydrogen sulphide per 100 cubic feet of Gas, as

determined by methods prescribed in Standards of Gas Service, Circular of the National

Bureau of Standards, No. 405, page 134 (1934 Edition), and shall be considered free from

hydrogen sulphide if a strip of white filter paper, moistened with a solution containing

freshly moistened with the same solution, after the first paper has been exposed to the

Gas for 1« minutes in an apparatus of approved form, through which the Gas is flowing at

the rate of approximately five cubic feet per hour, the Gas from the jet not impinging

directly upon the test paper; or the hydrogen sulphide content may be determined by an

instrument of approved type and by approved methods when mutually agreeable to the



(c) Shall not contain more than 20 grains of total sulphur (including the sulphur in any

(d) Shall not at any time have an oxygen content in excess of one percent by volume, and the

Parties hereto shall make every reasonable effort to keep the Gas free of oxygen;


(e) Shall not contain more than seven (7) pounds of water per million cubic feet of Gas



(f) Shall not contain more than three (3) percent by volume of carbon dioxide; provided,
