1. Scope

1.1 This specification covers fuel blend grades of 6 to 20 volume percent (%) biodiesel with the remainder being a light middle or middle distillate diesel fuel, collectively designated as B6 to B20. These grades are suitable for various types of diesel engines.

1.1.1 The biodiesel component of the blend shall conform to the requirements of Specification D 6751 . The remainder of the fuel shall be a light middle or middle distillate grade diesel fuel conforming to Specification D 975 grades No. 1-D and No. 2-D of any sulfur level specified with the following exceptions. The light middle or middle distillate grade diesel fuel whose sulfur level, aromatic level, cetane, or lubricity falls outside of Specification D 975 may be blended with biodiesel meeting Specification D 6751 , provided the finished mixtures meets this specification.

1.1.2 The fuel sulfur grades are described as follows:

1.1.2.1 Grade B6 to B20 S15 A fuel with a maximum of 15 ppm sulfur.

1.1.2.2 Grade B6 to B20 S500 A fuel with a maximum of 500 ppm sulfur.

1.1.2.3 Grade B6 to B20 S5000 A fuel with a maximum of 5000 ppm sulfur.

1.2 This specification prescribes the required properties of B6 to B20 biodiesel blends at the time and place of delivery. The specification requirements may be applied at other points in the production and distribution system when provided by agreement between the purchaser and the supplier.

1.2.1 Nothing in this specification shall preclude observance of federal, state, or local regulations that may be more restrictive.

Note 1The generation and dissipation of static electricity can create problems in the handling of distillate diesel fuel oils. For more information on this subject, see Guide D 4865 .

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
