shall be used throughout the term of this Agreement, except in

standards and charts shall be used. LNG level measuring

devices shall be approved by both TLC and Pan National. Each

tank shall be equipped with two level-measuring devices of

different types.

12.2 The density of the LNG shall be calculated using the

revised Klosek and McKinley method.

12.3 The temperature of the LNG contained in the tanks of

any LNG tanker shall be determined by using the arithmetic

average of the temperatures indicated by special thermo-couples

or resistance thermometers spaced at various locations from top

to bottom of each tank with an accuracy of plus or minus

two-tenths of a degree centigrade. Such temperatures shall be

either logged or printed.

12.4 Samples of the LNG shall be taken with a frequency

adequate to assure a representative analysis of the LNG being

unloaded, at a suitable point between the Discharge Point and

TLC's storage facilities. The sampling device shall be such as

to permit the total and continuous vaporization of a quantity

of LNG sufficient for the taking of a gaseous sample

representative of the LNG then being delivered. Such samples
