1.1 This test method covers the determination of the no flow point and pour point of petroleum products, liquid fuels, biodiesel, and biodiesel blends using an automatic instrument.
1.2 The measuring range of the apparatus is from –95 °C to 45 °C, however the precision statements were derived only from samples with no flow point temperatures from –77 °C to +2 °C and samples with pour point in the temperature range of –58 °C to +12 °C.
1.3 Pour point results from this test method can be reported at 1 °C or 3 °C intervals.
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 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.
