Scope*1.1 This specification covers four grades of biodiesel(B100) for use as a blend component with middle distillatefuels. These

3、grades are described as follows:1.1.1 Grade No. 1-B S15A special purpose biodieselblendstock intended for use in middle distillate fuel applica-tions which can be sensitive to the presence of partially reactedglycerides, including those applications requiring good lowtemperature operability, and als

4、o requiring a fuel blend com-ponent with 15 ppm sulfur (maximum).1.1.2 Grade No. 1-B S500A special purpose biodieselblendstock intended for use in middle distillate fuel applica-tions which can be sensitive to the presence of partially reactedglycerides, including those applications requiring good l

5、owtemperature operability, and also requiring a fuel blend com-ponent with 500 ppm sulfur (maximum).1.1.3 Grade No. 2-B S15A general purpose biodieselblendstock intended for use in middle distillate fuel applica-tions that require a fuel blend component with 15 ppm sulfur(maximum).1.1.4 Grade No. 2-

6、B S500A general purpose biodieselblendstock intended for use in middle distillate fuel applica-tions that require a fuel blend component with 500 ppm sulfur(maximum).1.2 This specification prescribes the required properties ofdiesel fuels at the time and place of delivery. The specificationrequireme

7、nts may be applied at other points in the productionand distribution system when provided by agreement betweenthe purchaser and the supplier.1.3 Nothing in this specification shall preclude observanceof federal, state, or local regulations which may be morerestrictive.NOTE 1The generation and dissip

8、ation of static electricity can createproblems in the handling of distillate fuel oils with which biodiesel maybe blended. For more information on the subject, see Guide D4865.1.4 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.

Terminology3.1 Definitions:3.1.1 biodiesel, nfuel comprised of mono-alkyl esters oflong chain fatty acids derived from vegetable oils or animalfats, designated B100.3.1.1.1 Discussionbiodiesel, as defined above, is regis-tered with the U.S. EPA as a fuel and a fuel a

29、dditive underSection 211(b) of the CleanAirAct (40 CFR Part 79). There is,however, other usage of the term biodiesel in the marketplace.Due to its EPA registration and the widespread commercial useof the term biodiesel in the U.S. marketplace, the termbiodiesel will be maintained for this specificat

30、ion.3.1.1.2 DiscussionBiodiesel is typically produced by areaction of a vegetable oil or animal fat with an alcohol such asmethanol or ethanol in the presence of a catalyst to yieldmono-alkyl esters and glycerin, which is removed.
