Does commercial biodiesel have an ASTM standard?
Biodiesel has a full ASTM standard. The American Society of Testing and Materials (ASTM)-the premier standard-setting organization in the United States-issued Specification D 6751 for all biodiesel fuel bought and sold in the U.S. A separate standard for B6-B20 blends has been passed by ASTM. It will be published later this year with its own ASTM number.
