1.1 This test method covers a method for evaluating the inherent storage stability of distillate fuels having flash points above 38 °C (100 °F), by Test Methods D93 , and 90 % distilled points below 340 °C (644 °F), by Test Method D86 . Note 1: ASTM specification fuels falling within the scope of this test method are Specification D396 , Grade Nos. 1 and 2; Specification D975 , Grades 1-D and 2-D; and Specification D2880 , Grades 1-GT and 2-GT. 1.2 This test method is not suitable for quality control testing but, rather it is intended for research use to shorten storage time relative to that required at ambient storage temperatures. 1.3 Appendix X1 presents additional information about storage stability and the correlation of Test Method D4625 results with sediment formation in actual field storage. 1.4 The values given in SI units are to be regarded as the standard. 1.4.1 Exception— The values in parentheses are for information only. 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. ====== Significance And Use ====== 5.1 Fuel oxidation and other degradative reactions leading to formation of sediment (and color) are mildly accelerated by the test conditions compared with typical storage conditions. Test results have been shown to predict storage stability more reliably than other more accelerated tests. See Appendix X1 for information on the correlation of test results with actual field storage. 5.2 Because the storage periods are long (4 weeks to 24 weeks), the test method is not suitable for quality control testing, but does provide a tool for research on storage properties of fuels. 5.3 Because environmental effects and the materials and nature of tank construction affect storage stability, the results obtained by this test are not necessarily the same as those obtained during storage in a specific field storage situation.
