1.1 This test method covers the determination of the temperature below which solid hydrocarbon crystals may form in aviation turbine fuels.
Note 1: This test method describes an alternative procedure and automatic apparatus which closely mimics the apparatus and procedure described in Test Method D2386.
1.2 The measuring range of the apparatus is from -70 °C to 0 °C, however the precision statements were derived only from samples with freezing point temperatures from -60 °C to -42 °C.
Note 2: Typical aviation fuel has freezing point temperatures in the -60 °C to -40 °C range.
1.3 Some results from this test method (14 % of samples included in the 2003 round robin2) incorrectly identified sample contamination where no contaminants were present in the samples (see research report2 for further information).
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 Section 7.
