Christian and Keith, As per ASTM D-6751, paragraph X1.21: "The flash point for biodiesel is used as the mechanism to limit the level of unreacted alcohol remaining in the finished fuel." As per ASTM D-6751, paragraph X1.22: "The flash point specification for biodiesel is also of importance in connection with legal requirements and safety precautions involved in fuel handling and storage, and is normally specified to meet insurance and fire regulations." Paragraph X1.23 discusses wide variability with the accepted test method. This resulted in 130*C being chosen to insure that a low end flash point of 100*C is never compromised. Improvements to testing are being evaluated, which could result in a revised standard at some point in the future.
