1.1 This test method covers the determination of the temperature below which solid hydrocarbon crystals may form in aviation turbine fuels and aviation gasoline.
1.2 The reporting range of freezing point test results considered valid for the applicability of precisions (r and R) and for the purpose of test result reporting per Practice D6300, is –70.3 °C to –35.3 °C. See 12.1.1.3 and 12.1.1.4 for details on the ILS summary and how this reporting range is calculated using the lowest and highest achieved ILS sample averages..
Note 1: The measuring range of the apparatus is from –80 °C to 20 °C; however, the precision has not been determined using results outside the reporting range in 1.2.
1.3 The interlaboratory study mentioned in 12.2.4 has demonstrated the test method with aviation gasolines having freezing points in the valid range of –63.8 °C to –42.9 °C for the applicability of precision (r and R) and for the purpose of test result reporting according to Practice D6300. See 12.2.5 for the ILS summary.
Note 2: The precision and relative bias assessments were derived from blended aviation gasolines.
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, health, and environmental practices and to determine the applicability of regulatory limitations prior to use.
1.6 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.
