6.5 Measuring Equipment Inaccuracy and Failure. The quantity of gas delivered hereunder

during periods when the measuring equipment is out of service or registering

inaccurately shall be estimated as follows:


(a) If, upon test, any measuring equipment, the readings of which are used in the

registration, integration, or computation of quantities of gas hereunder, is found

to be in error to the extent that it introduces not more than 2% measurement error

in the individual measuring equipment affected, previous records of such equipment

shall be considered accurate.


(b) If, upon test, any such above measuring equipment is found to be inaccurate to the

extent that it causes the registered or computed quantities of the instrument(s)

so affected to be in error by an amount exceeding 2% at a recording corresponding

to the average hourly rate of flow through the instrument(s) in the period since

the last preceding test, then any registrations, integration, or computed

quantities of such instruments affected shall be corrected to zero error for any

part of the period since the last test in which such error is known to have

existed or which may be agreed upon by representatives of the parties. In case

the period of such error is not known definitely or agreed upon, such correction

shall be for a period of one-half of the elapsed time since the date of the last

test, but not exceeding a correction period of sixteen days.
