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.
