Standard Test Method for Assessing Distillate Fuel Storage Stability by Oxygen Overpressure

SCOPE
1.1 This test method covers a procedure for assessing the potential storage stability of middle distillate fuels such as Grade No. 1D and Grade No. 2D diesel fuels, in accordance with Specification D975.
1.2 This test method is applicable to either freshly refined fuels or fuels already in storage.
1.3 This test method is suitable for fuels containing stabilizer additives as well as fuels containing no such additives.
1.4 Appendix X1 provides information on other suggested test times and temperatures for which this test method may be used.
1.5 The values in SI units are to be regarded as the standard. The values given in parentheses are for information only and are only approximate equivalents.
1.6 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 precautionary statements see Notes4.1, 6.2, 6.3, 7.4 and 10.1.
