shall be analyzed by means of a suitable gas chromatograph.

The analysis or the average of such analyses shall determine

the molecular composition of the LNG. A calibration of the

chromatograph utilized shall be performed before the analysis

of the samples taken from each unloading. Representatives of

Pan National shall have the right to be present, but the

absence of a duly summoned representative of Pan National shall

not prevent the carrying out of calibration and sampling. Such

calibration shall be effected with the aid of a gaseous mixture

having a known composition closely similar to the vaporized LNG

being measured.

12.5 The Gross Heating Value of LNG shall be calculated on

the basis of its molecular composition and of the molecular

weights and the thermies per kilogram of each of its

components. The values of physical constants to be used for

such calculations are set forth in Annex A hereto. Such values

shall be revised by mutual agreement from time to time to

conform with those contained in the most current publications

of the National Bureau of Standards of the United States or

those of any corresponding national institution the standards

of which are approved by such institution of the country in
