and seventy-three hundredths pounds per square inch absolute

(14.73 psia) and under standard gravitational force (acceleration

of 980.665 cm per second per second) with air of the same

temperature and pressure as the gas when the products of

combustion are cooled to the initial temperature of the gas and

air and when the water formed by combustion is condensed to the

liquid state. The gross heating value so determined shall be

corrected from the conditions of testing to that of the actual

condition of the gas as delivered expressed in Btu's per cubic

foot. Standardize the reporting basis for gross heating value as

Btu(IT)/cubic foot at standard conditions of 14.73 psia, 60

degrees F, and dry. For gross heating value based on cubic

meters, the reporting standard is megajoules/cubic meter at

standard conditions of 101.325 kPa, 15 degrees C, and dry. (For

reference one megajoule equals one million joules). Standardize

the reporting basis for gas volumes as cubic foot at standard

conditions of 14.73 psia, and 60 degrees F. For gas volumes

reported in cubic meters, the standard conditions are 101.325 kPa

and 15 degrees C. If the gas as delivered contains seven (7)

pounds of water vapor or less per one million (1,000,000) cubic

feet, such gas shall be assumed to have zero (0) pounds of water

per one million (1,000,000) cubic feet (dry gas); however, if the

gas delivered contains greater than (7) pounds of water vapor per

one million (1,000,000) cubic feet, Transporter will correct the

gross heating value for the actual water content..

 

hydrocarbons or of hydrocarbons and non-combustible gases, in

gaseous state, consisting essentially of methane.

 

quantity of natural gas occupying a volume of one thousand

(1,000) cubic feet at a temperature of sixty degrees Fahrenheit

(60EF.) and at a pressure of fourteen and seventy-three

hundredths pounds per square inch absolute (14.73 psia).

 

 

nominations, scheduling, confirmations, allocations, invoicing

and balancing in the United States. The standard for Canada

shall be Gigajoules per gas day. (For reference 1 Dekatherm =

1,000,000 Btu’s; and 1 Gigajoule = 1,000,000,000 joules.) For

commercial purposes, the standard conversion factor between

Dekatherm and Gigajoules should be 1.055056 Gigajoules per

Dekatherm. The standard Btu is the International Btu, which is

also called the Btu (IT); the standard joule is the joule

specified in the SI system of units.
