ASTM D5972 : 25

Standard Test Method for Freezing Point of Aviation Fuels (Automatic Phase Transition Method)

Standard Details

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 freezing point temperature range of –80 ºC to 20 ºC; however, the precision statements were derived from a D6300-compliant Inter-laboratory 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 according to Practice D6300, see 12.1.3.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 7.1, 7.3, and 7.5.

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.
