Pure biodiesel, sometimes referred to as FAME (Fatty Acid Methyl Esters), or B100, are specified in ASTM D6751.

Blends of B100 with petrodiesel (ASTM D975) are named based on the percentage of B100 in the blend, ie B6 is 6% B100 to 94% petrodiesel. The ranges of B6 to B20 are in specification D7467. Each of these specifications has a slate of tests that may be performed to qualify the fuels. We carry instruments and manual apparatus for many of these tests.
