38、ally equivalent to 3.9 lb per thousand barrels of the solid dye standard Solvent Red 164, or thetax must be collected.B Under United States of America regulations, Grades B6-20 S5000 are required by 40 CFR part 80 to contain a sufficient amount of the dye Solvent Red 164 so itspresence is visually a
39、pparent. At or beyond terminal storage tanks, they are required by 26 CFR Part 48 to contain the dye Solvent Red 164 at a concentration spectrallyequivalent to 3.9 lb per thousand barrels of the solid dye standard Solvent Red 26.C If Grade No. 1-D or blends of Grade No. 1-D and Grade No. 2-D diesel
40、fuel are used, the minimum viscosity shall be 1.3 mm2/s.D If Grade No. 1-D or blends of Grade No. 1-D and Grade No. 2-D diesel fuel are used, or a cloud point of less than -12C is specified, the minimum flash point shall be38C.E It is unrealistic to specify low temperature properties that will ensur
41、e satisfactory operation at all ambient conditions. In general, cloud point (or wax appearance point)Low Temperature Flow Test, and Cold Filter Plugging Point Test may be useful to estimate vehicle low temperature operability limits but their use with B6 to B20 has notbeen validated. However, satisf
42、actory operation below the cloud point (or wax appearance point) may be achieved depending on equipment design, operating conditions,and the use of flow-improver additives as described in X3.1.2. Appropriate low temperature operability properties should be agreed upon between the fuel supplier andpu
43、rchaser for the intended use and expected ambient temperatures. Test Methods D4539 and D6371 may be especially useful to estimate vehicle low temperatureoperability limits when flow improvers are used but their use with B6 to B20 from a full range of biodiesel feedstock sources has not been validate
44、d. Due to fuel deliverysystem, engine design, and test method differences, low temperature operability tests may not provide the same degree of protection in various vehicle operating classes.Tenth percentile minimum air temperatures for U.S. locations are provided in Appendix X3 as a means of estim
45、ating expected regional temperatures. The tenth percentileminimum air temperatures may be used to estimate expected regional target temperatures for use withTest Methods D2500, D4539, and D6371. Refer to X3.1.3 for furthergeneral guidance on test application.F Calculated cetane index approximation,
46、Test Method D4737, is not applicable to biodiesel blends.G Low ambient temperatures, as well as engine operation at high altitudes, may require the use of fuels with higher cetane ratings. If the diesel fuel is qualified underTable 1of Specification D975 for cetane, it is not necessary to measure th
47、e cetane number of the blend. This is because the cetane number of the individual blend componentswill be at least 40, so the resulting blend will also be at least 40 cetane number.H These test methods are specified in 40 CFR Part 80.I If the diesel fuel is qualified under Table 1 of Specification D
48、975 for lubricity, it is not necessary to measure the lubricity of the blend. This is because the lubricity of theindividual blend components will be less than 520 micron (m) so the resulting blend will also be less than 520 (m).J Other sulfur limits can apply in selected areas in the United States
