Flash Point Testing

Method Pensky Martens Closed Cup Method (PMCC)
Standards ASTM D93

What is it used for?

The Pensky Martens Closed-Cup Method is a means of determining flash point for liquid samples.


How does it work?

A cup is filled with a test specimen and fitted with a cover. The sample is then heated and stirred at the same time. An ignition source is then directed into the cup at regular intervals with simultaneous interruption of stirring until a flash that spreads throughout the inside of the cup is seen. The corresponding temperature is its flash point.


What do the results tell us?

The flash point of a sample can provide insight not only into its relative volatility, but also with regard to fuel dilution, contamination and makeup.
