Flash Point by Automated Tag Closed Cup

For the determination of the flash point of liquids with a viscosity below 5.5 mm2/s (cSt) at 40°C (104°F), or below 9.5 mm2/s (cSt) at 25°C (77°F), and a flash point below 93°C (200°F). The specimen is placed in the cup of the tester and, with the lid closed, heated at a slow constant rate. An ignition source is directed into the cup at regular intervals.
