Description
ASTM1250-
1980 Table 24B
This table provides CTL factors for correcting volumes of gasolines at observed
temperatures to the volume at 60 F. Use this table if the following conditions exist.
 The liquid is a refined product
 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 0.6535-1.0760. 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.
ASTM1250-
1980 Table 24E
This table provides CTL factors for correcting volumes of light hydrocarbons at observed
temperatures to the volume at 60 F. Use this table if the following conditions exist.
 The liquid is a NGL or LPG (propane)
 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 0.3500-0.6880. 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.
ASTM1250-
1980 Table 53B
This table is used to correct observed density at the observed temperature to a density at
15 C. When this table is activated, the corrected density is then automatically used in Table
54B, which provides CTL factors for correcting volumes of gasolines at observed
temperatures to the volume at 15 C. Use this table if the following conditions exist.
 The liquid is a refined product
 Observed Density is to be corrected to 15 C and used in Table 54B
 Reference Temperature is 15 C
After selecting this table, enter the Density of the liquid at the observed temperature. The
valid range of Density is from 653-1075 kg/m3. Test temperatures can be entered on this
screen that will calculate a CTL based on the test temperature and the Density. The test
temperature and Calculated CTL are for informational purposes and will not be used in
calculations during operations.
ASTM1250-
1980 Table 54
This table provides CTL factors for correcting volumes of crude oil at observed
temperatures to the volume at 15 C. Use this table if the following conditions exist.
 The liquid is crude oil
 Density at 15 C is known
 Reference Temperature is 15 C
After selecting this table, enter the Density of the liquid at 15 C. The valid range of Density
is from 500-600 kg/m3. Test temperatures can be entered on this screen that will calculate
a CTL based on the test temperature and the Density. The test temperature and Calculated
CTL are for informational purposes and will not be used in calculations during operations.
