API reference tables
Reference tables are organized by reference temperature, CTL derivation method, liquid type, and
density unit. The table selected here controls all the remaining options.
• Reference temperature:
If you specify a 5x, 6x, 23x, or 24x table, the default reference temperature is 60 °F, and
-
cannot be changed.
- If you specify a 53x or 54x table, the default reference temperature is 15 °C. However, you
can change the reference temperature, as recommended in some locations (for example, to
14.0 or 14.5 °C).
• CTL derivation method:
- If you specify an odd-numbered table (5, 23, or 53), CTL will be derived using method 1
described above.
- If you specify an even-numbered table (6, 24, or 54), CTL will be derived using method 2
described above.
• The letters A, B, C, or D that are used to terminate table names define the type of liquid that the
table is designed for:
- A tables are used with generalized crude and JP4 applications.
- B tables are used with generalized products.
- C tables are used with liquids with a constant base density or known thermal expansion
coefficient.
- D tables are used with lubricating oils.
• Different tables use different density units:
- Degrees API
- Relative density (SG)
- Base density (kg/m
Table 8-3 summarizes these options.
