Closed Cup Flash Point

Closed cup flash point is the lowest temperature of a liquid in a small
closed cup at which the vapors above a liquid surface reach a concentration
in air that ignites when exposed to a pilot flame, as determined by a specific
test method. The ASTM D93 test method employs the Pensky-Martens
closed-cup tester that includes the use of a stirrer which maintains a
uniform liquid composition during the test.
