Flash Point Analysis

Analytical Testing to Determine Product Flashpoint

Flash Point is defined as the lowest temperature at which a liquid (usually a petroleum product) will form a vapor in the air (near its surface) that will “flash,” or briefly ignite, on exposure to an open flame.

The flash point test is used to determine the classification under which a product can be shipped while complying with Department of Transportation (DOT) regulations. It is also used by companies to fulfill the Safety Data Sheet requirements of the new Global Harmonized System. 

There are numerous Flash Point techniques depending on the products being tested. In the closed-cup flash-point test, a brass test cup is filled with a test specimen and fitted with a cover. The sample is heated and stirred at specified rates depending on the material that is being tested. An ignition source is 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.

Other flash point techniques are:
 Tag Closed Cup      ASTM D56
 Pensky Marten      ASTM D93
 Tag Open cup      ASTM D1310
 Seta Flash/Small Scale Tester      ASTM D3828/3278
