The 50% D86 point and 50% TBP point can be converted:
Tt50 = 0.87180 x Td501.0258
To determine the difference between adjacent point measurements use the following formula:
ΔTt = A*ΔTdB
where
-
ΔTt = Difference in TBP point in °F
-
ΔTd = Difference in D86 point in °F
A and B can be determined from the cut point range using the following table.
