2、ar 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 types of die
3、sel 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 special-pur
4、pose,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 applicationsrequiring a

6、th 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 andload.21.1.6 Grade No.2-D S50
7、00A 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 use in low-and medium-speeddiesel eng
8、ines in applications involving predominantly con-stant speed and load.NOTE1A more detailed description of the grades of diesel fuel oils isgiven in X1.2.NOTE2The Sxxx designation has been adopted to distinguish gradesby sulfur rather than using words such as“Low Sulfur”as previouslybecause the numbe
9、r 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 not inthe previous grade system and are commonly
10、 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 this specification shall preclude observanceof fede
11、ral,state,or local regulations which can be morerestrictive.NOTE3The generation and dissipation of static electricity can createproblems in the handling of distillate diesel fuel oils.For more informa-tion on the subject,see Guide D4865.1.3 The values stated in SI units are to be regarded asstandard
