The biodiesel industry's standard for biodiesel fuel  is known as ASTM D 6751.  The ASTM (American Society for Testing and Materials) is a US organization that defines the principals for ASTM grade biodiesel fuel.  This organization upholds a high standard within the industry and is comprised of fuel producers, engine equipment manufacturers, and third party interest groups (users, government agencies, and independent consultants)  The ASTM's rigorous standards make their ballot process rather complicated.  In fact, a single negative vote is enough to defeat a ballot all together.  It is ultimately a true consensus organization.  Some of the ASTM standards can take 10 years or more to gain a consensus making the entire process quite time consuming. Click here to view current ASTM D6751 specifications

ASTM fuel standards are the minimum accepted values within the biodiesel industry in order to provide customer satisfaction and/or protection.  Technical reviews are necessary to secure ASTM approved fuel and provide the engine community and customers with the necessary information they need to assure biodiesel blends are problem free.
