43、e 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 12 C is specified, the minimum flash point shallbe 38 C.EIt is unrealistic to specify low temperature properties that will ensure satisfactory operation at all ambient conditions. In general, c
44、loud 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 cloud point (or wax appearance point)
45、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 and expected ambient temperatures. T
46、est 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 validated. Due to fuel deliverysystem, engine design, and test method dif
47、ferences, 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 temperatures. The tenth percentileminimum
48、 air temperatures may be used to estimate expected regional target temperatures for use with Test Methods D2500, D4539, and D6371. Refer to X3.1.3 for furthergeneral guidance on test application.FOther sulfur limits can apply in selected areas in the United States and in other countries.GCalculated
49、cetane index approximation, Test Method D4737, is not applicable to biodiesel blends.HLow 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 under Table 1of Specification D975 for cetane, it is not necessary to measure the 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.IThese test methods are specified in 40
