IP 16: Determination of the freezing point of aviation fuels — Manual method

Overview:

This standard describes a manual procedure for determining the temperature below which solid hydrocarbon crystals are present in aviation turbine fuels or aviation gasolines. This standard is applicable to aviation turbine fuels with freezing points in the range of -42 °C to -60 °C. The test method can be used to determine values outside this range but there is no precision for these values. If no crystallization point or freezing point can be measured this test can be used to determine the lowest measurable temperature before the crystallization point. NOTE - The sample matrix on which the precision of this standard is based did not include aviation gasoline.
