Flash Point

Processing Specification:

Flash Point is defined as the lowest temperature at which vapors of a material will ignite upon application of an ignition source. The test is conducted under specific test conditions in accordance with ASTM D93. Determination of the flash point is important for the safe handling, storage, and transportation of liquid fuels. Although biodiesel is generally non-hazardous, inadequate methanol recovery during the biodiesel production process will result in a low flash point.

ASTM D6751 Requirement: minimum 93°C. If the flash point is less than 130°C (but greater than 93°C), then methanol recovery must be demonstrated by headspace gas chromatography in accordance with EN 14110.
