Scope

4.1 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.

4.2 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.

4.3 Flash point can indicate the possible presence of highly volatile and flammable materials in a relatively non-volatile or non-flammable material.

4.4 In cases where Test Method D2887 data are available, that is, for determination of boiling range distribution or calculation of other physical properties, this test method provides a calculation method for flash point without performing an additional analysis. Table 1 shows the ranges for the IBP, 58201;%, and 108201;% results for each equation.

4.5 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 D2887 data. The value computed from the equation is termed the “calculated flash point.” The calculated flash point formula is applicable to diesel fuel samples based on a correlation to Test Method D93 over the range from 478201;°C to 998201;°C, and to jet fuel samples based on a correlation to Test Method D56 and Test Method D3828 over the range from 358201;°C to 678201;°C.

1.2 The calculated flash point formula is valid for diesel and jet fuels with an IBP between 908201;°C and 1628201;°C (1948201;°F and 3248201;°F), Test Method D2887 58201;% recovery temperature between 1368201;°C and 2078201;°C (2778201;°F and 4058201;°F), and Test Method D2887 108201;% recovery temperature between 1428201;°C and 2228201;°C (2888201;°F and 4328201;°F). For each flash point test method (Test Method D56, Test Method D93, and Test Method D3828) a separate equation has been established. See 4.4 for a detailed overview of the simulated distillation IBP, 58201;%, and 108201;% ranges per equation.

1.3 A calculated diagnostic parameter, not exceeding a given threshold value, is a prerequisite for acceptance of the calculated flash point.
