1、Designation: D975 13Standard 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 t
2、he 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 o
3、f 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 S500A
4、special-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 applic

8、e 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 “Low
9、 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 in
11、 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.

37、eaning treatment and inert gas purging; and the reverseprocedure where a high vapor pressure product is added to acontainer that previously held a low vapor pressure product.3.1.3.1 DiscussionSince middle distillate fuels have flashpoints above 38C, during normal distribution of these fuels,the atmo
38、sphere 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. However, when the pre-vious load in the compartment was a volatile, flammable fuelsuc
39、h as gasoline, and if some residual fuel vapor or mistremains in the compartment, and the container has a mixture ofair and fuel vapor or mist (that is, not purged with an inert gas),then there is a risk that the atmosphere in the container beingfilled could be in the explosive range creating a haza

41、xcluding added oxygenatedmaterials. (See Note 5.)3.2.1.1 DiscussionNeither macro nor micro emulsions areincluded in this definition since neither are homogeneousmixtures or solutions.3.2.1.2 DiscussionExamples of excluded oxygenated ma-terials are alcohols, esters, ethers and triglycerides.3.2.2 S(n
42、umerical specification maximum)indicates themaximum sulfur content, in weight ppm (g/g), allowed by thisspecification in a diesel fuel grade.3.2.2.1 DiscussionOf the seven diesel fuel grades speci-fied in this standard, six have important distinguishing maxi-mum sulfur regulatory requirements.These
43、are Grades No. 1-DS15, No. 1-D S500, No. 1-D S5000, No. 2-D S15, No. 2-DS500 and No. 2-D S5000. 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 system.Thus, Gra
44、de No. 4-Ddoes not have the designation S20000 as part of its grade name.4. Sampling, Containers, and Sample Handling4.1 It is strongly advised to review all test methods prior tosampling to understand the importance and effects of samplingtechnique, proper containers, and special handling required
45、foreach test method.4.2 Correct sampling procedures are critical to obtaining arepresentative sample of the diesel fuel oil to be tested. Referto Appendix X2 for recommendations. The recommendedprocedures or practices provide techniques useful in the propersampling or handling of diesel fuels.5. Tes
46、t 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 limits. ForGrades
47、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. In casesof dispu
48、te, 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, D5772,orD5773
49、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.
