is the method for determining the
flash point of fuels,
solvents, cutback asphalts, and some
light lube fractions, utilizing a covered container in which the test sample
is heated and periodically exposed to a small flame introduced through a
shuttered opening. The lowest temperature at which the vapors above the
sample briefly ignite is the flash point.
