DSCR F18E: DETERMINATION OF QUANTITY

F18E   52.211-9G56       DETERMINATION OF QUANTITY       DSCR (SEP 1996)
AND
F11F45

    (a)  The quantity of supplies furnished under this contract shall be 
determined by one of the following methods:

         (1)  The Contractor shall provide delivery equipment that enables 
the receiving activity and the Contractor to determine quantity at destination 
in the delivery conveyance by one of the following:

              (i)  Calibrated meter (in areas where environmental restrictions 
prohibit the opening of dome hatches prior to, during, or after off-loading, 
calibrated meter must be used); or

             (ii)  Certified capacity tables.  The tables must be made available 
at the time of delivery; or

            (iii)  Certified tank calibration markers.  Certified tank calibration 
markers will not be accepted unless the conveyance is full to the marker and the 
entire quantity is off-loaded at the receiving activity.

         (2)  The Contractor and the receiving activity may mutually agree in 
writing to determine quantity by inventories of the receiving tank(s) just prior 
to and after delivery.  For each contract line item mutually agreed to under this 
section, the Contractor shall submit one copy of the written mutual agreement to 
the DSCR contract administrator.

         (3)  The Contractor and the receiving activity may mutually agree in 
writing to accept the net quantity determined at the loading point using a 
calibrated loading rack meter.  For each contract line item mutually agreed to 
under this section, the Contractor shall submit one copy of the written mutual 
agreement to the DSCR contract administrator.

              (i)  This quantity must be mechanically printed on the loading 
rack meter ticket that is generated by the loading rack meter.  In addition, 
the loading rack meter ticket must contain whatever additional information the 
receiving activity specified when they agreed in writing to use this method.

             (ii)  Such quantity will be accepted only if the conveyance is 
sealed at the loading point with serially numbered seals, the seal numbers are 
recorded on the meter ticket at the loading point, and all seals are intact upon 
arrival at the receiving activity.  The Contractor must affirm in writing that 
the conveyance was sealed at the loading point.

            (iii)  If this method is being used, the Government reserves the 
right to determine the quantity received in gallons at 60 degrees Fahrenheit 
(or liters at 15 degrees Centigrade) at any time and by any valid means available.  
If the difference between the quantity determined at the loading point and the 
quantity determined by the Government at the receiving point exceeds 0.5 percent 
of the quantity determined at the loading point or if the difference is attributed 
to a source other than measurement techniques, the net quantity determined by 
the Government will be the quantity received.

         (4)  In any case, at the Government's option, quantity may be determined 
at the receiving activity on the basis of--

              (i)  Weight, using calibrated scales; or

             (ii)  A calibrated meter on the receiving tank system.

    (b)  WATER BOTTOMS.  Every delivery must be free of all water bottoms prior 
to discharge, and the Contractor is responsible for their removal and disposal.

    (c)  VOLUME CORRECTION.  Volume correction to gallons at 60 degrees Fahrenheit 
(or liters at 15 degrees Centigrade) is required for all product volumes of 
lubricating oils measured in tank trucks, trucks and trailers, and tank wagons.

    (d)  MEASUREMENT STANDARDS.  All measurements and calibrations made to determine 
quantity shall be in accordance with the most recent edition of the API Manual of 
Petroleum Measurement Standards.  Certified capacity tables shall mean capacity 
tables prepared by an independent inspector or any independent surveyor.  In addition, 
the following specific standards will be used as applicable:

         (1)  API Manual of Petroleum Measurement Standards Chapter 7, Method of 
Measuring the Temperature of Petroleum Products (API 2543/ASTM D 1086).  In areas 
where the metric system is used, an equivalent type Centigrade thermometer may be 
used.

         (2)  API Manual of Petroleum Measurement Standards Chapter 9, Section 1, 
Density Determination (ASTM D 1298).

         (3)  API Manual of Petroleum Standards Chapter 3, Method of Gauging 
Petroleum Products (API 2545/ASTM D 1085).

         (4)  API Manual of Petroleum Measurement Standards Chapter 11.1, Volume 
Correction Factors (API 2540/ASTM D 1250/IP 200).  Either the printed version or 
the computer subroutine version of the standard may be used.

              (i)  Use Volume XIII, Tables 5D and 6D (or Volume XIV, Tables 53D 
and 54D) for lubricating oils.

             (ii)  Volume XII, Table 52, shall be used to convert cubic meters at 
15 degrees Centigrade to barrels of 60 degrees Fahrenheit, except when this method 
is restricted by foreign law.  Convert liters at 15 degrees Centigrade to cubic 
meters at 15 degrees Centigrade by dividing by 1,000.  Convert gallons at 60 degrees 
Fahrenheit to barrels at 60 degrees Fahrenheit by dividing by 42.

            (iii)  If the original measurement is by weight, using calibrated 
scales, then--

                   (A)  Volume XI, Table 8, shall be used to convert pounds to U.S. 
gallons at 60 degrees Fahrenheit.

                   (B)  Volume XII, Table 58, shall be used to convert metric tons 
to U.S. gallons at 60 degrees Fahrenheit.

         (5)  API Manual of Petroleum Measurement Standards Chapter 4, Proving 
Systems.  All meters used in determining product volume shall be calibrated using 
this standard with the frequency required by local regulation (foreign or domestic).  
If no local regulation exists, then the frequency of calibration shall be that 
recommended by the meter manufacturer or every 6 months, whichever is more frequent.

    (e)  UNITS OF QUANTITY.

         (1)  Depending upon the unit shown in the Schedule, the unit of quantity, 
as used in this contract, shall be--

              (i)  The U.S. gallon of 231 cubic inches;

             (ii) The liter of 61.026 cubic inches.

         (2)  Unless otherwise specified in the contract, a reference to gallons 
shall mean U.S. gallons.
