Designation:D811517(Reapproved 2021)Standard Test Method forRubber PropertyAbrasion Resistance(Multi-DirectionalPlatform Abrader)1This standard is issued under the fixed designation D8115;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.1.Scope1.1 This test method covers the measurement of abrasionresistance of rubbers(vulcanized thermoset rubbers and ther-moplastic elastomers)that are subject to abrasive/frictionalwear in actual service.The abrasion resistance is measured bysimultaneously moving 4 test pieces across the surface ofabrasive sheets in a soft lissajous movement,and is expressedas volume loss in cubic millimeters where a smaller numberindicates better abrasion resistance.1.2 Test results obtained by this test method shall not beassumed to represent the wear behavior of rubber products inactual service.1.3 Results obtained by this test have shown to be similar tothose obtained using Test Method D5963 and ISO 4649.1.4 The values stated in SI units are to be regarded as thestandard.The values in parentheses are for information only.1.5 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.1.6 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:2D297 Test Methods for Rubber ProductsChemical Analy-sisD2240 Test Method for Rubber PropertyDurometer Hard-nessD5963 Test Method for Rubber PropertyAbrasion Resis-tance(Rotary Drum Abrader)E177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method2.2 ISO Standards:3ISO 868 Plastics and EboniteDetermination of IndentationHardness by Means of a Durometer(Shore Hardness)ISO 2781 Rubber,VulcanizedDetermination of DensityISO4649 Rubber,vulcanizedorthermoplasticDetermination of abrasion resistance using a rotatingcylindrical drum deviceISO 7619 RubberDetermination of Indentation Hardnessby Means of Pocket Hardness Meters3.Terminology3.1 Definitions:3.1.1 abrasion loss,A,(mm3),nthe volume loss of adefined rubber test piece determined by sliding the test pieceunder specified conditions over the surface of an abrasive sheetmounted to an abrading table of specified dimensions.4.Summary of Test Method4.1 This test method provides procedures for preparing testpieces of specified dimensions from vulcanized thermosetrubbers or thermoplastic elastomers and for evaluating theirabrasion resistance by sliding a test piece across the surface ofan abrasive paper attached to an abrading table.4.2 The test is performed under specified conditions ofcontact pressure,sliding distance,travel speed of the test piece,and the degree of abrasiveness of the abrasive sheet.These areoutlined in 7.1.4.3 The abrasion resistance is reported as abrasion loss(volume)in cubic millimeters and is calculated from the mass1This test method is under the jurisdiction of ASTM Committee D11 on Rubberand Rubber-like Materials and is the direct responsibility of Subcommittee D11.15on Degradation Tests.Current edition approved May 1,2021.Published July 2021.Originally approvedin 2017.Last previous edition approved in 2017 as D8115 17.DOI:10.1520/D8115-17R21.2For 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.3Available from International Organization for Standardization(ISO),ISOCentral Secretariat,BIBC II,Chemin de Blandonnet 8,CP 401,1214 Vernier,Geneva,Switzerland,http:/www.iso.org.Copyright 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.1loss of the test piece and density of the test rubber.A smallernumber indicates a higher resistance to abrasion.5.Significance and Use5.1 Abrasion resistance is a performance factor of para-mount importance for many rubber products,such as tires,conveyo
