Scope*1.1 This specification covers seven grades of diesel fuel oils suitab
3、le for various types of diesel engines. These grades aredescribed as follows:1.1.1 Grade No. 1-D S15A special-purpose, light middle distillate fuel for use in diesel engine applications requiring a fuelwith 15 ppm sulfur (maximum) and higher volatility than that provided by Grade No. 2-D S15 fuel.21
4、.1.2 Grade No. 1-D S500A special-purpose, light middle distillate fuel for use in diesel engine applications requiring a fuelwith 500 ppm sulfur (maximum) and higher volatility than that provided by Grade No. 2-D S500 fuel.21.1.3 Grade No. 1-D S5000Aspecial-purpose, light middle distillate fuel for
5、use in diesel engine applications requiring a fuelwith 5000 ppm sulfur (maximum) and higher volatility than that provided by Grade No. 2-D S5000 fuels.1.1.4 Grade No. 2-D S15A general purpose, middle distillate fuel for use in diesel engine applications requiring a fuel with15 ppm sulfur (maximum).
6、It is especially suitable for use in applications with conditions of varying speed and load.21.1.5 Grade No. 2-D S500A general-purpose, middle distillate fuel for use in diesel engine applications requiring a fuel with500 ppm sulfur (maximum).

8、stillate and residual oil, for use in low- and medium-speed dieselengines in applications involving predominantly constant speed and load.NOTE 1A more detailed description of the grades of diesel fuel oils is given in X1.2.NOTE 2The Sxxx designation has been adopted to distinguish grades by sulfur r
9、ather than using words such as “Low Sulfur” as previously becausethe number of sulfur grades is growing and the word descriptions were thought to be not precise. S5000 grades correspond to the so-called “regular” sulfurgrades, the previous No. 1-D and No. 2-D. S500 grades correspond to the previous
10、“Low Sulfur” grades. S15 grades were not in the previous grade systemand are commonly referred to as “Ultra-Low Sulfur” grades or ULSD.1.2 This specification, unless otherwise provided by agreement between the purchaser and the supplier, prescribes the requiredproperties of diesel fuels at the time
11、and place of delivery.1.2.1 Nothing in this specification shall preclude observance of federal, state, or local regulations which can be more restrictive.NOTE 3The generation and dissipation of static electricity can create problems in the handling of distillate diesel fuel oils.

36、ith 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 switch loading, nof liquid fuels, the practice of loading low vapor pressure product (for example, diesel fuel) into anempty or near-empty fixed or portable c
37、ontainer that previously held a high or intermediate vapor pressure product (such asgasoline or solvent) without prior compartment cleaning treatment and inert gas purging; and the reverse procedure where a highvapor pressure product is added to a container that previously held a low vapor pressure
38、product.3.1.3.1 DiscussionSince middle distillate fuels have flash points above 38C, during normal distribution of these fuels, theatmosphere above the fuels in a container such as a tanker truck, rail car, or barge, is normally below the lower explosive limit,so there is low risk of fire or explosi
39、on should an electrostatic discharge (spark) occur. However, when the previous load in thecompartment was a volatile, flammable fuel such as gasoline, and if some residual fuel vapor or mist remains in the compartment,and the container has a mixture of air and fuel vapor or mist (that is, not purged
40、 with an inert gas), then there is a risk that theatmosphere in the container being filled could be in the explosive range creating a hazard should an electrostatic discharge occur.3.2 Definitions of Terms Specific to This Standard:3.2.1 hydrocarbon oil, nhomogeneous mixture or solution with element
41、al composition primarily of carbon and hydrogen andalso containing sulfur consistent with the limits in Table 1, oxygen or nitrogen from residual impurities and contaminants andexcluding intentionally added oxygenated materials. (See Note 5.)3.2.1.1 DiscussionNeither macro nor micro water emulsions
42、are included in this definition since neither are homogeneousmixtures or solutions.3.2.1.2 DiscussionExamples of excluded oxygenated materials are alcohols, esters, ethers and triglycerides.3.2.2 S(numerical specification maximum)indicates the maximum sulfur content, in weight ppm (g/g), allowed by
43、thisspecification in a diesel fuel grade.3.2.2.1 DiscussionOf the seven diesel fuel grades specified in this standard, six have important distinguishing maximumsulfur regulatory requirements. These are Grades No. 1-D S15, No. 1-D S500, No. 1-D S5000, No. 2-D S15, No. 2-D S500 andNo. 2-D S5000.The se
44、venth grade, No. 4-D, is distinguished from these other grades by many major properties in addition to sulfur(unregulated maximum), and therefore is not included in this designation system. Thus, Grade No. 4-D does not have thedesignation S20000 as part of its grade name.4. Sampling, Containers, and
45、 Sample Handling4.1 It is strongly advised to review all test methods prior to sampling to understand the importance and effects of samplingtechnique, proper containers, and special handling required for each test method.4.2 Correct sampling procedures are critical to obtaining a representative samp
46、le of the diesel fuel oil to be tested. Refer toAppendix X2 for recommendations. The recommended procedures or practices provide techniques useful in the proper samplingor handling of diesel fuels.5. Test Methods5.1 The requirements enumerated in this specification shall be determined in accordance
47、with the following methods:5.1.1 Flash PointTest Methods D93, except where other methods are prescribed by law. For all grades, Test Method D3828may be used as an alternate with the same limits. For Grades No. 1-D S15, No. 1-D S500 , No. 1-D S5000, No. 2-D S15, No. 2-DS500, and No. 2-D S5000, Test M
48、ethod D56 may be used as an alternate with the same limits, provided the flash point is below93C and the viscosity is below 5.5 mm2/s at 40C. This test method will give slightly lower values. In cases of dispute, TestMethods D93 shall be used as the referee method. Test Method D56 may not be used as
49、 the alternate method for Grade No. 4-Dbecause its minimum viscosity limit is 5.5 mm2/s at 40C.5.1.2 Cloud PointTest Method D2500. For all fuel grades in Table 1, the automatic Test Methods D5771, D5772, or D5773can be used as alternates with the same limits. Test Method D3117 can also be used since it is closely related to Test MethodD2500. In case of dispute, Test Method D2500 shall be the referee method.4Available from U.S. Government Printing Office, Superintendent of Documents, 732 N.
