Method 1010A Water

Flash Point by Pensky-Martens Closed-Cup Method

This method is for the determination of flash point (ignitability) using a Pensky-Martens closed-cup procedure.  The sample is heated at a slow, constant rate with continual stirring.  A small flame is directed into the cup at regular intervals with simultaneous interruption of stirring. The flash point is the lowest temperature at which application of the test flame ignites the vapor above the sample.

The method is applicable to liquids including those that tend to form a surface film under test conditions.  Liquids containing non-filterable, suspended solids can also be tested using this method.

NOTE:  This method is an update of and replaces Method 1010.
