Currently, my company offers a lower-priced B100 Biodiesel testing package which we call the Critical ASTM D 6751 Testing Package. It is listed for $250.00 and includes the following analysis: Total & Free Glycerin, Acid Number, Flash Point and Oxidation Stability. We set this package up for new biodiesel producers to check their product and save them some money upfront. Do you think this is a valid testing package or should we add another test to it?
