GENERAL TERMS AND CONDITIONS

Measurement

3. MEASUREMENT

3.1 Measurement Unit. The unit of gas deliverable

hereunder shall be one Dt, measured as provided below.

3.2 Quantity and Heating Value Determination. The quantity

and heating value of gas received or delivered by

Pipeline shall be determined as follows:

A. Standardize the reporting basis for BTU as 14.73

psia and 60 degrees F (101.325 kPa and 15 degrees C

and dry). Standardize the reporting basis for

gigacalorie as 1.035646 Kg/cm² and 15.6 degrees C

and dry.

Standardize the reporting basis for gas volumes as

cubic foot at standard conditions of 14.73 psia, 60

degrees F, and dry. For gas volumes reported in cubic

meters, the standard conditions are 101.325 kPa, 15

degrees C, and dry.

B. The unit of weight for the purpose of

measurement shall be one pound mass of gas.

C. The average absolute atmospheric pressure

shall be assumed to be fourteen and four-tenths

pounds to the square inch (14.4 psi),

irrespective of actual elevation or location of

the Delivery Point above sea level or variations

in such atmospheric pressure from time to time.

D. The temperature of the gas flowing through

meters, when necessary for computing gas

quantities, shall be determined for any day by the

use of instantaneous temperature measurements

applied to measuring equipment, by the use of a

properly installed continuous recorder, or by

assuming 60 degrees
