ASTM D5972-99a PDF

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 20°C; however, the ASTM interlaboratory study mentioned in 12.4 has only demonstrated the test method with fuels having freezing points in the range of -45 to 65°C.

1.3 The user shall exercise appropriate caution when this test method is used in testing Jet B and JP 4 samples (see 12.3).

1.4 The values stated in SI units are to be regarded as the standard.

1.5 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. For specific hazard statements see 7.1, 7.3, and 7.5.
