Significance and Use | ||||||||||||||
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, 5%, and 10% 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. Scope | ||||||||||||||
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 47 to 99°C, and to jet fuel samples based on a correlation to Test Method D56 and Test Method D3828 over the range from 35 to 67°C. 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 D2887 5% recovery temperature between 136 and 207°C (277 and 405°F), and Test Method D2887 10% recovery temperature between 142 and 222°C (288 and 432°F). For each flash point test method (Test Method D56, Test Method D93, and Test Method D3828) a separate equation has been established. See 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 MSPE1.5 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. |
