35、ion Method83. Terminology3.1 Definitions:3.1.1 biodiesel, nfuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats,designated B100.3.1.1.1 Discussionbiodiesel, as defined above, is registered with the U.S. EPAas a fuel and a fuel additive under Sectio

36、n 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 thewidespread commercial use of the term biodiesel in the U.S. marketplace, the term biodiesel will be maintained for thisspecification.3.1.1.2 Discus

37、sionBiodiesel is typically produced by a reaction of a vegetable oil or animal fat with an alcohol such as methanol or ethanol in thepresence of a catalyst to yield mono-alkyl esters and glycerin, which is removed. The finished biodiesel derives approximately10 % of its mass from the reacted alcohol

38、. The alcohol used in the reaction may or may not come from renewable resources.3.1.2 biodiesel blend (BXX), nblend of biodiesel fuel with diesel fuel oils.3.1.2.1 DiscussionIn the abbreviation BXX, the XX represents the volume percentage of biodiesel fuel in the blend.3.1.3 biodiesel fuel, nsynonym

39、 for biodiesel.3.1.4 diesel fuel, nmiddle petroleum distillate fuel.3.1.5 free glycerin, na measure of the amount of glycerin remaining in the fuel.3.1.6 Grade S15 B100, na grade of biodiesel meetingASTM Specification D6751 and having a sulfur specification of 15 ppm15 ppm maximum.3.1.7 Grade S500 B

40、100, na grade of biodiesel meeting ASTM Specification D6751 and having a sulfur specification of 500ppm 500 ppm maximum.3.1.8 middle distillate fuel, nkerosines and gas oils boiling between approximately 150C150 C and 400C400 C at normalatmospheric pressure and having a closed-cup flash point above

41、38C.38 C.3.1.9 monoglyceride, na partially reacted fat or oil molecule with one long chain alkyl ester group on a glycerin backbone.3.1.10 total glycerin, nthe sum of the free glycerin and the glycerin portion of any unreacted or partially reacted oil or fat.4. Requirements4.1 The biodiesel specifie

42、d shall be mono-alkyl esters of long chain fatty acids derived from vegetable oils and animal fats.4.2 Unless otherwise specified, samples for analysis shall be taken by the procedure described in Practices D4057 or D4177.4.3 The biodiesel specified shall conform to the detailed requirements shown i

43、n Table 1.NOTE 2Aconsiderable amount of experience exists in the U.S. with a 20 % blend of biodiesel, primarily produced from soybean oil, with 80 % dieselfuel (B20). Experience with biodiesel produced from animal fat and other oils is similar. Experience with B20 and lower blends in other applicati

44、ons isnot as prevalent.Although biodiesel (B100) can be used, blends of over 20 % biodiesel with diesel fuel (B20) should be evaluated on a case by case basisuntil further experience is available.NOTE 3The user should consult the equipment manufacturer or owners manual regarding the suitability of u

45、sing biodiesel or biodiesel blends in aparticular engine or application.5. Test Methods5.1 The requirements enumerated in this specification shall be determined in accordance with the following methods.5.1.1 Flash PointTest Methods D93, except where other methods are prescribed by law. Test Methods

46、D3828 or D6450 canalso be used. The precision and bias of Test Methods D3828 and D6450 with biodiesel is not known and is currently underinvestigation. Test Methods D93 shall be the referee method.5.1.2 Water and SedimentTest Method D2709. Test Method D1796 may also be used. Test Method D2709 shall

47、be the refereemethod. The precision and bias of these test methods with biodiesel is not known and is currently under investigation.D6751 15a4TABLE 1 Detailed Requirements for Biodiesel (B100) Blend StocksProperty Test MethodA Grade No. 1-BS15 Grade No. 1-BS500 Grade No. 2-BS15 Grade No. 2-BS500Sulf
