| description abstract | 5.1 The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals that can restrict the flow of fuel through filters if present 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 tank temperature. 5.2 Petroleum blending operations require precise measurement of the freezing point. 5.3 This test method expresses results to the nearest 0.1 °C, and it eliminates most of the operator time and judgment required by manual Test Method D2386. 5.4 When a specification requires Test Method D2386, do not substitute this test method or any other test method. | |

| 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 freezing point temperature range of –80 ºC to 20 ºC; however, the precision statements were derived from a Practice D6300-compliant interlaboratory study (ILS) with a lowest achieved sample average of −69.86 °C and a highest achieved sample average of −37.81 °C. 1.2.1 For the range of test results considered valid for the applicability of precisions (r and R) and for the purpose of test result reporting per Practice D6300, see 12.1.3. 1.3 Units—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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. | |
