ASTM D6751-24

1.1.1 Grade No. 1-B S15—A special purpose biodiesel blendstock intended for use in middle distillate fuel applications which can be sensitive to the presence of partially reacted glycerides, including those applications requiring good low temperature operability, and also requiring a fuel blend component with 15 ppm sulfur (maximum).

1.1.2 Grade No. 1-B S15 LM—A special purpose biodiesel blendstock intended for use in middle distillate fuel applications which can be sensitive to the presence of partially reacted glycerides, including those applications requiring good low temperature operability, and also requiring a fuel blend component with 15 ppm sulfur (maximum) and combined sodium, potassium, calcium, and magnesium of 4 ppm (maximum). LM indicates Low Metals suitable for diesel engine applications with Selective Catalytic Reduction (SCR) or Diesel Particulate Filter (DPF) aftertreatment technology.

1.1.3 Grade No. 1-B S500—A special purpose biodiesel blendstock intended for use in middle distillate fuel applications which can be sensitive to the presence of partially reacted glycerides, including those applications requiring good low temperature operability, and also requiring a fuel blend component with 500 ppm sulfur (maximum).

1.1.4 Grade No. 2-B S15—A general purpose biodiesel blendstock intended for use in middle distillate fuel applications that require a fuel blend component with 15 ppm sulfur (maximum).

1.1.5 Grade No. 2-B S15 LM—A general purpose biodiesel blendstock intended for use in middle distillate fuel applications that require a fuel blend component with 15 ppm sulfur (maximum) and combined sodium, potassium, calcium, and magnesium of 4 ppm (maximum). LM indicates Low Metals suitable for diesel engine applications with Selective Catalytic Reduction (SCR) or Diesel Particulate Filter (DPF) aftertreatment technology.

1.1.6 Grade No. 2-B S500—A general purpose biodiesel blendstock intended for use in middle distillate fuel applications that require a fuel blend component with 500 ppm sulfur (maximum).
