3. Terminology
3.1 Definitions:
3.1.1 biodiesel, n—a fuel comprised of mono-alkyl esters of
long chain fatty acids derived from vegetable oils or animal
fats, designated B100.
3.1.2 biodiesel blends, n—a blend of biodiesel fuel with
petroleum-based diesel fuel.
3.1.3 dynamic, adj—in petroleum products—in petroleum
product flash point test methods—the condition where the
vapor above the test specimen and the test specimen are not in
temperature equilibrium at the time that the ignition source is
applied.
3.1.3.1 Discussion—This is primarily caused by the heating
of the test specimen at the constant prescribed rate with the
vapor temperature lagging behind the test specimen temperature.
3.1.4 equilibrium, n— in petroleum products—in petroleum
product flash point test methods—the condition where the
vapor above the test specimen and the test specimen are at the
same temperature at the time the ignition source is applied.
3.1.4.1 Discussion—This condition may not be fully
achieved in practice, since the temperature may not be uniform
throughout the test specimen, and the test cover and shutter on
the apparatus can be cooler.
3.1.5 flash point, n— in petroleum products, the lowest
temperature corrected to a barometric pressure of 101.3 kPa
(760 mm Hg), at which application of an ignition source causes
the vapors of a specimen of the sample to ignite under specified
conditions of test
