Does biodiesel have an ASTM standard?
Biodiesel has a full ASTM standard. In 2002, ASTM International, formerly known as the American Society of Testing and Materials (ASTM) – the premier standard-setting organization in the United States – issued Specification D6751 for all biodiesel fuel bought and sold in the United States. This is now the standard that covers B100 as a blending component. In 2008, they expanded the specifications to incorporate a set for blends of B5 or less (ASTM D975) and B6 to B20 (ASTM D7467).
