1、Designation: D975 12aStandard Specification forDiesel Fuel Oils1This standard is issued under the fixed designation D975; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates
2、the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers seven grades of diesel fuel oilssuitable for various types
3、of diesel engines. These grades aredescribed as follows:1.1.1 Grade No. 1-D S15A special-purpose, light middledistillate fuel for use in diesel engine applications requiring afuel with 15 ppm sulfur (maximum) and higher volatility thanthat provided by Grade No. 2-D S15 fuel.21.1.2 Grade No. 1-D S500
4、Aspecial-purpose, light middledistillate fuel for use in diesel engine applications requiring afuel with 500 ppm sulfur (maximum) and higher volatility thanthat provided by Grade No. 2-D S500 fuel.21.1.3 Grade No. 1-D S5000A special-purpose, lightmiddle distillate fuel for use in diesel engine appli
5、cationsrequiring a fuel with 5000 ppm sulfur (maximum) and highervolatility than that provided by Grade No. 2-D S5000 fuels.1.1.4 Grade No. 2-D S15A general purpose, middle dis-tillate fuel for use in diesel engine applications requiring a fuelwith 15 ppm sulfur (maximum). It is especially suitable
6、for usein applications with conditions of varying speed and load.21.1.5 Grade No. 2-D S500A general-purpose, middledistillate fuel for use in diesel engine applications requiring afuel with 500 ppm sulfur (maximum). It is especially suitablefor use in applications with conditions of varying speed an
7、dload.21.1.6 Grade No. 2-D S5000A general-purpose, middledistillate fuel for use in diesel engine applications requiring afuel with 5000 ppm sulfur (maximum), especially in conditionsof varying speed and load.1.1.7 Grade No. 4-DA heavy distillate fuel, or a blend ofdistillate and residual oil, for u
8、se in low- and medium-speeddiesel engines in applications involving predominantly con-stant speed and load.NOTE 1Amore detailed description of the grades of diesel fuel oils isgiven in X1.2.NOTE 2The Sxxx designation has been adopted to distinguish gradesby sulfur rather than using words such as “Lo
9、w Sulfur” as previouslybecause the number of sulfur grades is growing and the word descriptionswere thought to be not precise. S5000 grades correspond to the so-called“regular” sulfur grades, the previous No. 1-D and No. 2-D. S500 gradescorrespond to the previous “Low Sulfur” grades. S15 grades were
10、 not inthe previous grade system and are commonly referred to as “Ultra-LowSulfur” grades or ULSD.1.2 This specification, unless otherwise provided by agree-ment between the purchaser and the supplier, prescribes therequired properties of diesel fuels at the time and place ofdelivery.1.2.1 Nothing i
11、n this specification shall preclude observanceof federal, state, or local regulations which can be morerestrictive.NOTE 3The generation and dissipation of static electricity can createproblems in the handling of distillate diesel fuel oils.

38、 fuels,the atmosphere above the fuels in a container such as a tankertruck, rail car, or barge, is normally below the lower explosivelimit, so there is low risk of fire or explosion should anelectrostatic discharge (spark) occur.

The seventh grade, No. 4-D, isdistinguished from these other grades by many major proper-ties in addition to sulfur (unregulated maximum), and thereforeis not included in this designation s
44、ystem.Thus, Grade No. 4-Ddoes not have the designation S20000 as part of its grade name.4.

Test Methods5.1 The requirements enumerated in this specification shallbe determined in accordance with the following methods:5.1.1 Flash PointTest Methods D93, except where othermethods are prescribed by law. For all grades, Test MethodD3828 may be used as an alternate with the same lim
47、its. ForGrades No. 1-D S15, No. 1-D S500 , No. 1-D S5000, No. 2-DS15, No. 2-D S500, and No. 2-D S5000, Test Method D56 maybe used as an alternate with the same limits, provided the flashpoint is below 93C and the viscosity is below 5.5 mm2/s at40C. This test method will give slightly lower values. I
48、n casesof dispute, Test Methods D93 shall be used as the refereemethod. Test Method D56 may not be used as the alternatemethod for Grade No. 4-D because its minimum viscosity limitis 5.5 mm2/s at 40C.5.1.2 Cloud PointTest Method D2500. For all fuel gradesin Table 1, the automatic Test Methods D5771,
49、 D5772,orD5773 can be used as alternates with the same limits. TestMethod D3117 can also be used since it is closely related toTest Method D2500. In case of dispute, Test Method D2500shall be the referee method.5.1.3 Water and SedimentTest Method D2709 is used forfuel Grades No. 1-D S15, No. 1-D S500, No. 1-D S5000, No.2-D S15, No. 2-D S500, and No. 2-D S5000.
