The flash point temperature is one measure of the tendency of the test specimen to form a flammable mixture with air under controlled laboratory conditions. It is only one of a number of properties that must be considered in assessing the overall flammability hazard of a material.
Flash point is used in shipping and safety regulations to define flammable and combustible materials. Consult the particular regulation involved for precise definitions of these classifications.
Flash point can indicate the possible presence of highly volatile and flammable materials in a relatively non-volatile or non-flammable material.
In cases where Test Method D 2887
In the case where the flash point of a fuel has been initially established, the calculated flash point is useful as a flash point check on subsequent samples of that fuel, provided its source and mode of manufacture remain unchanged.
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 18212;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 28212;The calculated flash point derived from simulated distillation data depends upon the accuracy of determination of the......
