With respect to the GPA TP-
15 standard the combination
of input values is:
0: In Range
1: Out of Range
The following range checks
apply:
For lower range:

0.350 <= RD60 <
0.425

-50 to (695.51*RD60
- 155.51) °F
Higher range:

0.676

-50 to 140 °F
with RD60 being the relative
density at 60°F

Calculations
The calculations depend on the conversion method.
Conversion method 1: from observed to standard conditions.
The function performs the following iterative algorithm to calculate the density at 20
°
C and the
equilibrium pressure.
