1、Designation: D975 15bStandard 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 U.S. Department of Defense.1. Scope*1.1 This specification covers seven grades of diesel fuel oilssuitable for various t
3、ypes 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
4、 S500Aspecial-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
5、applicationsrequiring 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 suit
6、able 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 spe
7、ed andload.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,
8、for use in low- and medium-speeddiesel engines in applications involving predominantly con-stant speed and load.NOTE 1A more 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
9、as “Low 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 grade
10、s were 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 Not
11、hing in 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.

41、terials are alcohols, esters, ethers, and triglycerides.3.1.3.3 DiscussionThe hydrocarbon oil may be manufac-tured from a variety of raw materials, for example petroleum(crude oil), oil sands, natural gas, coal, and biomass. AppendixX7 discusses some matters for consideration regarding the useof die
42、sel fuels from feedstocks other than petroleum.3.1.4 switch loading, nof liquid fuels, the practice ofloading low vapor pressure product (for example, diesel fuel)into an empty or near-empty fixed or portable container thatpreviously held a high or intermediate vapor pressure product(such as gasolin
43、e or solvent) without prior compartmentcleaning 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.3.1.4.1 DiscussionSince middle distillate fuels have flashpoints above 38 C, during n
44、ormal distribution of these 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. However, when the pre-vious load in the com
45、partment was a volatile, flammable fuelsuch 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
46、 be in the explosive range creating a hazard shouldan electrostatic discharge occur.3.2 Definitions of Terms Specific to This Standard:3.2.1 S(numerical specification maximum)indicates themaximum sulfur content, in weight ppm (g/g), allowed by thisspecification in a diesel fuel grade.3.2.1.1 Discuss
47、ionOf the seven diesel fuel grades speci-fied in this standard, six have important distinguishing maxi-mum sulfur regulatory requirements.These 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
48、 grades by many major proper-ties in addition to sulfur (unregulated maximum), and thereforeis not included in this designation system.Thus, Grade 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 al
49、l test methods prior tosampling to understand the importance and effects of samplingtechnique, proper containers, and special handling required 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.
