5.2 Testing Measuring Equipment:


Southern LNG shall test its meters at reasonable intervals. Southern LNG shall test

thermometers, gravitometers, calorimeters, chromatographs, and other equipment at reasonable

intervals. Southern LNG will notify Customer in time to permit Customer to witness, at its

expense, these tests if Customer so elects. Measuring equipment shall be subject to check

tests and inspection by Customer at its expense, on notice, at all reasonable times.


5.3 Correction of Metering Errors:


If Southern LNG's measurement equipment is found to be inoperative or inaccurate, such

equipment shall be adjusted to register correctly, and the amount of error shall be determined

by the most accurate method feasible. If the inaccuracy shall have resulted in an error of

more than 2% in the measurement of gas, then the calculated deliveries of gas shall be adjusted

to compensate for such error. Such adjustment shall be made for such period of inaccuracy as

may be definitely known. If the period of inaccuracy shall not be definitely known, then such

adjustment shall be made for the last half of the period (but not exceeding 15 days) between

the time the metering equipment was adjusted to register correctly and the date of the last

previous meter test. If for any reason the measuring equipment is out of service or out of

repair so that the amount of gas delivered cannot be ascertained or computed from the readings

thereof, the amount of gas delivered during such period shall be estimated and agreed upon by

the use of the first of the following methods which is feasible: (a) by using the registration

of any check measuring equipment if installed and accurately registering; (b) by correcting the

error if the percentage of error is ascertainable by calibration, test or mathematical

calculation; or (c) by estimating the quantity of gas delivered by reference to actual

deliveries during preceding periods under similar conditions when the equipment in question was

registering accurately.
