Anotace textu normy ASTM D6751-23a :
This specification covers biodiesel fuel blend stock, B100, in Grades S15 and S500 for use as a blend component with middle distillate fuels. This specification prescribes the required properties of diesel fuels at the time and place of delivery. The requirements stated here may be applied at other points in the production and distribution system when provided by agreement between the purchaser and the supplier. The biodiesel specified shall be mono-alkyl esters of long chain fatty acids derived from vegetable oils and animal fats. The product shall undergo chemical analysis for flash point, methanol, water and sediment, kinematic viscosity, sulfated ash, oxidation stability, sulfur, copper strip corrosion, cetane number, cloud point, acid number, carbon residue, total and free glycerin, phosphorus, reduce pressure distillation temperature, atmospheric equivalent temperature, combined calcium and magnesium, and combined sodium and magnesium.

1.1?This specification covers six grades of biodiesel (B100) for use as a blend component with middle distillate fuels. These grades are described as follows: 1.1.1?Grade No. 1-B S15A 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 LMA 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 modern exhaust aftertreatment. 1.1.3?Grade No. 1-B S500A 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 S15A 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 LMA 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 modern exhaust aftertreatment. 1.1.6?Grade No. 2-B S500A general purpose biodiesel blendstock intended for use in middle distillate fuel applications that require a fuel blend component with 500 ppm sulfur (maximum). 1.2?This specification prescribes the required properties of diesel fuels 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. 1.3?Nothing in this specification shall preclude observance of federal, state, or local regulations which may be more restrictive. Note 1:?The generation and dissipation of static electricity
can create problems in the handling of distillate fuel oils with
which biodiesel may be blended. For more information on the
subject, see Guide D4865.
1.4?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
