A brass test cup of specified dimensions, filled to the
inside mark with test specimen and fitted with a cover of
specified dimensions, is heated and the specimen stirred at
specified rates, by either of two defined procedures (A or B).
An ignition source is directed into the test cup at regular
intervals with simultaneous interruption of the stirring, until a
flash is detected (see 3.1.3.1). The flash point is reported as
defined in 3.1.3.
