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 automated apparatus which mimics the apparatus and procedure described in Test Method D 2386.
1.2 The measuring range of the apparatus is from 0 to − 70°C. The precision statements were derived from samples with freezing point temperatures from − 45 to − 65°C.
NOTE 2--Typical aviation fuel has freezing point temperatures in the − 40 to − 65°C range. Samples with higher freezing points were not available for the current interlaboratory program.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Notes 3-7.
