1.1 This test method covers the calculated flash point formula, which represents a means for directly estimating the flash point temperature of distillate fuels from Test Method D 2887
1.2 The calculated flash point formula is valid for diesel and jet fuels with an IBP between 90 and 162°C (194 and 324°F), Test Method D 2887
1.3 A calculated diagnostic parameter, not exceeding a given threshold value, is a prerequisite for acceptance of the calculated flash point.
1.4 The diagnostic parameter MSPEX (Mean Summed Prediction Error) checks the sample compliance, based on reconstruction of TIBP, T5%, and T10% of the sample, via a calculation procedure. A value for MSPEX not exceeding the threshold level of 1.9°C is a prerequisite for accepting the calculated flash point, CFP.
Note 1—It is important to note that calculated flash point results, at this time, are not recognized by regulatory organizations in verifying conformance to applicable regulations.
Note 2—The calculated flash point derived from simulated distillation data depends upon the accuracy of determination of the IBP temperature and the 5% and 10% recovery temperatures.
Note 3—If the user''s specification requires a defined flash point test method other than this test method, neither this test method nor any other test method should be substituted for the prescribed test method without obtaining comparative data and an agreement from the specifier.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
