39、b per thousand barrels of the solid dye standard Solvent Red 164, orthe tax must be collected.BUnder 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 apparent. At or beyond ter

40、minal 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.CIf Grade No. 1-D or blends of Grade No. 1-D and Grade No. 2-D diesel fuel are used, the minimum

41、 viscosity shall be 1.3 mm2/s.DIf 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 shallbe 38C.EIt is unrealistic to specify low temperature properties that will ensure satisfactory operation at

42、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, satisfactory operation below the c

43、loud 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 andpurchaser for the intended use

44、 and expected ambient temperatures. Test Methods D 4539 and D 6371 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 validated. Due to fuel deliverysys

45、tem, 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 estimating expected regional te

46、mperatures. The tenth percentileminimum air temperatures may be used to estimate expected regional target temperatures for use with Test Methods D 2500, D 4539, and D 6371. Refer to X3.1.3 forfurther general guidance on test application.FCalculated cetane index approximation, Test Method D 4737, is

47、not applicable to biodiesel blends.GLow 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 1 of Specification D 975 for cetane, it is not necessary to measure the cetane number of th

48、e blend. This is because the cetane number of the individual blendcomponents will be at least 40, so the resulting blend will also be at least 40 cetane number.HThese test methods are specified in 40 CFR Part 80.IIf the diesel fuel is qualified under Table 1 of Specification D 975 for lubricity, it

49、is not necessary to measure the lubricity of the blend. This is because the lubricity ofthe individual blend components will be less than 520 micron (m) so the resulting blend will also be less than 520 (m).TABLE 2 Sulfur Test MethodsSulfur Test Method Range Grades Units Used to Report ResultsAD 129(referee)0.1 mass % S5000 mass %D 1266 0.0005 to 0.4 mass %5 to 4000 mg/kg (wt ppm)S500 mass %D 1552 0.06 mass % S5000 mass %D 2622(referee for S500 grades)0.0003 to 5.3 mass %3 to 53 000 mg/kg (wt ppm)all grades mass %D 3120 3.0 to 100 mg/kg (wt
