Designation:D227414(Reapproved 2019)Designation:38897Standard Test Method forOxidation Stability of Distillate Fuel Oil(AcceleratedMethod)1This standard is issued under the fixed designation D2274;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 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.Scope1.1 This test method covers the measurement of the inherentstability of middle distillate petroleum fuels under specifiedoxidizing conditions at 95 C.NOTE1Fuels used in establishing the precision measures for this testmethod were described as gas oil,diesel fuel,No.2 heating oil,and DFM,a Navy distillate fuel suitable for diesels,boilers,and gas turbines.(Theterm DFM is no longer used when referring to fuel meeting MIL-F-16884requirements;rather it is called F76 as it conforms to NATO F76requirements.)While the test method may be used for fuels outside therange of these fuels,the precision measures may not apply.1.2 This test method is not applicable to fuels containingresidual oil.This test method has not been validated for testingbiodiesel,such as meeting Specification D6751 or blends ofmiddle distillates and biodiesel,such as meeting SpecificationD7467,or both.Test Method D7462 has been determined to besuitable for testing B100 and all blends of middle distillatesand biodiesel.NOTE2No.1 and No.2 grades in Specifications D396 or D975currently allow up to 5%biodiesel meeting Specification D6751.Samplescontaining biodiesel can result in partial dissolution or compromise of themembrane filter and give erroneous results.1.3 The values given in SI units are to be regarded as thestandard.The values in parentheses are for information only.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D381 Test Method for Gum Content in Fuels by Jet Evapo-rationD396 Specification for Fuel OilsD943 Test Method for Oxidation Characteristics of InhibitedMineral OilsD975 Specification for Diesel FuelD1193 Specification for Reagent WaterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD4625 Test Method for Middle Distillate Fuel StorageStability at 43 C(110 F)D6751 Specification for Biodiesel Fuel Blend Stock(B100)for Middle Distillate FuelsD7462 Test Method for Oxidation Stability of Biodiesel(B100)and Blends of Biodiesel with Middle DistillatePetroleum Fuel(Accelerated Method)(Withdrawn 2016)3D7467 Specification for Diesel Fuel Oil,Biodiesel Blend(B6 to B20)2.2 Military Specification:4MIL-F-16884 Fuel,Navy Distillate3.Terminology3.1 Definitions of Terms Specific to This Standard:1This test method is under the jurisdiction of Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.14 on Stability,Cleanliness and Compatibility of Liquid Fuels.Current edition approved Dec.1,2019.Published December 2019.Originallyapproved in 1964.Last previous edition approved in 2014 as D2274 14.DOI:10.1520/D2274-14R19.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from Standardization Documents Order Desk,Bldg.4,700 RobbinsAve.,Philadelphia,PA 19111-5098.Attn:NPODSCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.1.1 adherentinsolubles(formerlyadherentgum),nmaterial which is produced in the course of stressingdistillate fuel under the conditions of this test and whichadheres to the glassware after fuel has been flushed from thesystem.3.1.2 filterable insolubles,nmaterial,which is produ
