The BQ-9000 program certifies biodiesel producers, marketers, and testing labs. The BQ-9000 program starts with the ASTM D6751 standard for biodiesel and adds a quality systems program to make sure biodiesel is sampled, tested, stored, blended, shipped, and distributed in a way that maintains high quality.

|Water and sediment, volume %||Per ASTM D6751||per ASTM D6751|
|Cloud point, °C||Per ASTM D6751||per ASTM D6751|
|Acid number, mg KOH/gm||Per ASTM D6751||per ASTM D6751|
|Free glycerin, % mass||Per ASTM D6751||per ASTM D6751|
|Total glycerin, % mass||Per ASTM D6751||per ASTM D6751|
|Sulfur, ppm||Per EPA requirements||per EPA requirements|
|Visual appearance||ASTM D4176 Procedure 2||2 max|
|Cold Soak Filterability Test, seconds||Per ASTM D6751||per ASTM D6751|
At least once every six months, a production lot shall be selected for full specification testing. Full specification testing includes all the specification in ASTM D6751 (most recent version) as well as visual appearance of the fuel according to the ASTM D4176 Procedure. Visual appearance is not a part of the ASTM D6751. Only one cetane number test per year is required.
