Designation:D804821a1Standard Test Method forEvaluation of Diesel Engine Oils in T-13 Diesel Engine1This standard is issued under the fixed designation D8048;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.1NOTEEditorially updated TMC governance information in June 2022.INTRODUCTIONThis test method is written for use by laboratories that use the portions of the test method that referto ASTM Test Monitoring Center(TMC)2services(see Annex A1 Annex A4).The TMC provides reference oils,and engineering and statistical services to laboratories that desireto produce test results that are statistically similar to those produced by laboratories previouslycalibrated by the TMC.In general,the Test Purchaser decides if a calibrated test stand is to be used.Organizations such astheAmerican Chemistry Council require that a laboratory utilize the TMC services as part of their testregistration process.In addition,the American Petroleum Institute and the Gear Lubricant ReviewCommittee of the Lubricant Review Institute(SAE International)require that a laboratory use theTMC services in seeking qualification of oils against their specifications.The advantage of using the TMC services to calibrate test stands is that the test laboratory(andhence the Test Purchaser)has an assurance that the test stand was operating at the proper level of testseverity.It should also be borne in mind that results obtained in a non-calibrated test stand may notbe the same as those obtained in a test stand participating in the ASTM TMC services process.Laboratories that choose not to use the TMC services may simply disregard these portions.ASTM International policy is to encourage the development of test procedures based on genericequipment.It is recognized that there are occasions where critical/sole-source equipment has beenapproved by the technical committee(surveillance panel/task force)and is required by the testprocedure.The technical committee that oversees the test procedure is encouraged to clearly identifyif the part is considered critical in the test procedure.If a part is deemed to be critical,ASTMencourages alternative suppliers to be given the opportunity for consideration of supplying the criticalpart/component providing they meet the approval process set forth by the technical committee.An alternative supplier can start the process by initiating contact with the technical committee(current chairs shown on ASTM TMC website).The supplier should advise on the details of the partthat is intended to be supplied.The technical committee will review the request and determinefeasibility of an alternative supplier for the requested replacement critical part.In the event that areplacement critical part has been identified and proven equivalent the sole-source supplier footnoteshall be removed from the test procedure.1.Scope*1.1 This test method covers an engine test procedure forevaluating diesel engine oils for oxidation performance char-acteristics in an engine equipped with exhaust gas recirculationand running on ultra-low sulfur diesel fuel.2This test methodis commonly referred to as the Volvo T-13.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.B0 on Automotive Lubricants.Current edition approved Oct.1,2021.Published October 2021.Originallyapproved in 2016.Last previous edition approved in 2021 as D8048 21.DOI:10.1520/D8048-21AE01.2The ASTM Test Monitoring Center will update changes in this test method bymeans of Information Letters.Information letters may be obtained from the ASTMTest Monitoring Center,203 Armstrong Drive,Freeport,PA 16229,Attention:Director.This edition incorporates revisions in all Information Letters through No.21-1.*A Summary of Changes section appears at the end of this standardCopyright 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.11.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.2.1 ExceptionWhere there is no direct SI equivalent,such as the units for screw threads,National Pipe Threads/diameters,tubing size,and single source supply equipmentspecifications.1.3 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 ap
