Standard Test Method for Freezing Point of Aviation Fuels (Automatic Phase Transition Method)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of the temperature below which solid hydrocarbon crystals form in aviation turbine fuels.
1.2 This test method is designed to cover the temperature range of 80 to 20C; however, 2003 Joint ASTM /IP Interlaboratory Cooperative Test Program mentioned in has only demonstrated the test method with fuels having freezing points in the range of 42 to 60C.
1.3 The values stated in SI units are to be regarded as the standard.
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.
Significance and Use
The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals. These crystals can restrict the flow of fuel through 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 produces results which have been found to be equivalent to Test Method D 2386
When specification requires Test Method D 2386
