9.4.1
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 in Section 9.3.2). 
-
If you specify an even-numbered table (6, 24, or 54), CTL will be derived using Method 2 
(described in Section 9.3.2).
The letters ABC, 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
3
)
Table 9-2 summarizes these options.
