ASTM D 5972 : 2025

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

1.2This 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.

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4This 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.
