 ^ATo meet special operating conditions, modifications of individual limiting requirements may be agreed upon between purchaser, seller, and manufacturer.

 ^BThe test methods indicated are the approved referee methods.

 ^CThe 6.0 mm²/s upper viscosity limit is higher than petrodiesel and should be taken into consideration when blending.

 ^DOther sulfur limits can apply in selected areas in the United States and in other countries.

 ^EThe cloud point of biodiesel is generally higher than petrodiesel and should be taken into consideration when blending.

 ^FCarbon residue shall be run on the 100 % sample.
