GENERAL TERMS

AND CONDITIONS

3.0 GAS MEASUREMENT (Cont'd)

3.2 Volume Measurement (cont'd)

(b) Calculations (cont'd)

(3) The specific gravity of the Gas shall be determined

by a recording gravitometer of standard manufacture

except that, if neither Party considers it

necessary to install a recording gravitometer,

continuous proportional flow sampling shall be made

with an Edwards-type Gas balance, or by such other

method as shall be mutually agreed upon.

(4) Corrections of volumes for deviation from Boyle's

tables published by the American Gas Association,

Gas Measurement Committee in the current edition of

Report No. 8, "Compressibility and

Supercompressibility for Natural Gas and Other

Hydrocarbon Gases," as superseded or amended from

time to time. Any other measurement corrections

shall be made by use of factors obtained from

tables published by the current edition of the

American Gas Association, Gas Measurement Committee

Report No. 3, as superseded or amended from time to

time.

3.3 Heating Value Measurement

(a) Equipment
