Scope

This standard specifies a procedure for the determination of the temperature below which solid hydrocarbon crystals are present in aviation turbine fuels. The standard is applicable to aviation turbine fuels with freezing points in the range of -70 °C to 0 °C. However the precision statements are only applicable over the range !60 °C to -42 °C.

NOTE - In the Round Robin data collecting exercise, from which the precision of this test method was calculated, 14 % of the results from IP 528 were reported warmer
than the mean results of the same samples when tested by IP 16 plus the IP 16 reproducibility. As a consequence it is possible that when determining freezing points using this method a falsely high result may be quoted which might falsely indicate a possible contamination. If this occurs it is recommended that the sample be reanalysed using another approved freezing point test method.
