Table
Description
ASTM1250-
1980 Table 6C
This table provides CTL factors for correcting volumes of petroleum liquids at observed
temperatures to the volume at 60 F. Use this table if the following conditions exist.
 The liquid is a refined product or crude oil
 Coefficient of Expansion @ 60 F is known
 Reference Temperature is 60 F
After selecting this table, enter the Coefficient of Thermal Expansion (alpha) of the liquid at
60 F. The valid range of alpha is from 0.000270-0.000930. The alpha will be entered as
270-930, however. Test temperatures can be entered on this screen that will calculate a
CTL based on the test temperature and the alpha. The test temperature and Calculated
CTL are for informational purposes and will not be used in calculations during operations.
ASTM1250-
1980 Table 6D
This table provides CTL factors for correcting volumes of lube oils at observed temperatures
to the volume at 60 F. Use this table if the following conditions exist.
 The liquid is a lube oil
 API Gravity @ 60 F is known
 Reference Temperature is 60 F
After selecting this table, enter the API Gravity of the liquid at 60 F. The valid range of API
Gravity is from -10 to 45 API. Test temperatures can be entered on this screen that will
calculate a CTL based on the test temperature and the API Gravity. The test temperature
and Calculated CTL are for informational purposes and will not be used in calculations
during operations.
ASTM1250-
1980 Table 23E
This table provides density at 60 F of light hydrocarbons at observed temperature and
density. Use this table if the following conditions exist.
 The liquid is a NGL or LPG (propane)
 Current Temperature and Density is available.
 Relative Density at 60 F is unknown
 Reference Temperature is 60 F
Test temperatures and densities can be entered on this screen that will calculate the
corrected density at the test temperature and density. The test temperature, density and
Calculated corrected density at 60 F are for informational purposes and will not be used in
calculations during operations.
Note: This table will not produce a CTL value, but this table may be used by other tables.
ASTM1250-
1980 Table 24A
This table provides CTL factors for correcting volumes of crude oil at observed
temperatures to the volume at 60 F. Use this table if the following conditions exist.
 The liquid is crude oil
 Relative Density at 60 F is known
 Reference Temperature is 60 F
After selecting this table, enter the Relative Density of the liquid at 60 F. The valid range of
Relative Density is from 0.6110-1.0760. Test temperatures can be entered on this screen
that will calculate a CTL based on the test temperature and the Relative Density. The test
temperature and Calculated CTL are for informational purposes and will not be used in
calculations during operations.
