IN THE MEASUREMENT OF PETROLEUM

AND PETROLEUM PRODUCTS
ASTM Designation: D 1087 - 60
ADOPTED, 1960.1
This Recommended Practice of the American
Society for Testing Materials is issued under
the fixed designation D 1087; the final number
indicates the year of original adoption or, in
the case of revision, the year of last revision.
Scope
1. This recommended practice describes procedures for voltJ,me
calculations and corrections in the measurement of petroleum and its
·liquid products.
Terminology
2. (a) Measured Quantity is the volume of material in a tank for a
given gage at the temperature observed at the time of gaging.
(b) Gross Quantity at 60 F. is the measured quantity converted to
the equivalent volume at 60 F. after deducting any free water and
sediment (FW & S) which may be present.
(c) Net Quantity at 60 F. is the gross quantity at 60 F. corrected
for any deducti'bl.e suspended water and sediment (SW & S) which
may be present. (All SW & S is deductible, unless otherwise speci­
fied by contract.)
NOTE.-ln crude oil measuring and testing, "FW & S" and "SW & S" are
frequently ref erred to as "BS & W," meaning respectively "Bottom" and "Basic"
Sediment and Water.
(d) Tables.-All references in this standard to tables followed by a

Under the standardization procedure of the Society, this recommended
practice is under the jurisdiction of the ASTM Committee D-2 on Petroleum
Products and Lubricants.

Prior to adoption, this recommended practice was published as tentative
from 1950 to 1960, being revised in 1952 and 1957.
In 1960, this recommended practice was adopted without revision. ·

number refer to the ASTM-IP Petroleum Measurement Tables
3
(American Edition) (ASTM Designation: D 1250; IP 200).
Use of Capacity Tables
3. Capacity tables showing quantities for either innage or outage
gages shall be based on accurate tank calibration data. The cali­
brations should be checked periodically and whenever repairs or al­
terations are made to a tank or compartment.
BASIC CALCULATIONS
Basic Calculations
4. (a) Measured Quantity.-Obtain the measured quantity for each
opening and closing gage directly from the capacity table. If the basis
of the table, innage or outage, is not the same as that of the gage,
convert the gage to the same basis as the table by deducting the
gage reading from the reference depth (gaging height).
(b) Free Water and Sediment Deduction.-Obtain the quantities of
free water and sediment, corresponding to each opening and closing
water gage from the capacity table and deduct them from the respec­
tive opening and closing measured quantities.
(c) Gross Quantity at 60 F.-Calculate the gross quantity at 60 F.
by multiplying the measured quantity, corrected for any free water
and secli.ment, by the volume correction factor which corresponds to
3
its gravity. Obtain this factor from Table 6 of Standard D 1250 ; for
liquefied petroleum gases obtain this factor from Table 34. The de­
livered or received gross quantity at 60 F. is the difference between
the gross quantities at 60 F. calculated from the opening and closing
gages.
(d) Net Quantity at 60 F.-Obtain the net quantity at 60 F. by
subtracting any suspended water and sediment which may be present
from the gross quantity at 60 F. When contracts make allowance for
some SW & S, the deductible quantity is the difference between
the total and the allowable quantities of SW & S.
(e) Tanks are usually calibrated in U.S. gallons or barrels. Convert
gallons to barrels by dividing by 42.
(j) Example.-The following data and calculations illustrate the
recommended procedure for calculating the gross and net quantities
of product at 60 F. measured in or delivered from a tank:
