Determination of a closed cup Flash Point of fuels, lubricating oils, liquids with suspensions of
solids and liquids that tends to form a surface film under test conditions. A 75mL test specimen is
heated at a slow constant rate with continual stirring in a brass test cup of specified dimensions
with cover of specified dimensions. An ignition source is directed into the test cup at regular
intervals with simultaneous interruption of the stirring. The flash point is the lowest liquid
temperature at which application of the ignition source causes the vapor of the test specimen of the
sample to ignite.
