Btu is the International Btu, which is also called the

Btu(IT). For reporting purposes, BTU conversion factors

should be reported to not less than 3 decimal places and

Pressure Base conversion factors should be reported to not

less than 6 decimals places. For calculation purposes,

not less than 6 decimal places should be used for both

conversion factors.

 

1.2 "Cubic foot" means the volume of gas which would

occupy a space of one cubic foot at a temperature of 60

degrees Fahrenheit and at a pressure of 14.73 pounds per

square inch absolute.

 

1.3 "Contract demand" means the volume of gas set forth

from time to time on Exhibit A of the transportation
