Significance and Use

The freezing point of an aviation fuel is an index of the lowest temperature of its utility for certain applications. Solid hydrocarbon crystals can restrict the flow of fuel in the fuel system of the aircraft. The temperature of the fuel in the aircraft tank normally decreases during flight depending on aircraft speed, altitude, and flight duration. The freezing point of the fuel must always be lower than the minimum operational fuel temperature.

Petroleum blending operations require precise measurement of the freezing point.

This test method expresses results with a resolution of 0.1°C.

This test method provides results that have been found to be equivalent to the results from Test Method D 2386 on identical samples. When the specification requires the use of Test Method D 2386, do not substitute this test method or any other method.


1.1 This test method covers the determination of the temperature below which solid hydrocarbon crystals may form in aviation turbine fuels.

Note 1—This test method describes an alternative procedure and automated apparatus which mimics the apparatus and procedure described in Test Method D 2386.

1.2 The measuring range of the apparatus is from 0 to -70°C. The precision statements were derived from samples with freezing point temperatures from -45 to -65°C.

Note 2—Typical aviation fuel has freezing point temperatures in the -40 to -65°C range. Samples with higher freezing points were not available for the current interlaboratory program.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see Section 7.
