Significance and Use | ||||||||
The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals which, if present in the fuel system of the aircraft, can restrict the flow of fuel through filters. 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 shall always be lower than the minimum operational fuel temperature. Petroleum blending operations require precise measurement of the freezing point. This test method expresses results to the nearest 0.1°C, and it eliminates most of the operator time and judgment required by Test Method D2386. When a specification requires Test Method D2386, do not substitute this test method or any other test method. |

1. Scope | ||||||||
1.1 This test method covers the determination of the temperature below which solid hydrocarbon crystals may form in aviation turbine fuels. 1.2 This test method is designed to cover the temperature range of -80 to 20°C; however, the interlaboratory study mentioned in 12.4 has only demonstrated the test method with fuels having freezing points in the range of -60 to -42°C. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 to determine the applicability of regulatory limitations prior to use. |
