Designation:F510/F510M14Standard Test Method forResistance to Abrasion of Resilient Floor Coverings Usingan Abrader with a Grit Feed Method1This standard is issued under the fixed designation F510/F510M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript 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 method2describes a laboratory procedure fordetermining the abrasion resistance of resilient flooring usingan abrader with a grit feeder.31.2 The equipment used in this test method is a modificationof the Taber abraser.The regular abrading wheels are replacedby leather clad brass wheels(rollers).As the specimen holderrotates,a grit-feeding device feeds aluminum oxide grit ontothe specimen before it passes under the leather clad brasswheels.Using the vacuum system incorporated in theapparatus,the used grit and abraded material are removed afterpassing under both wheels.1.3 This test method employs a rotary,rubbing actioncaused by loose abrasive grit and the two abrading wheels.Onewheel rubs the specimen from the center outward and the otherfrom the outside toward the center.The wheels traverse acomplete circle and have an abrasive action on the rotatingspecimen at all angles.This action approaches the twistingaction between shoe and floor that occurs when a person turns.The use of loose grit serves the function of an abradant and alsoaids in the rolling action characteristic of normal walking.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:4D792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or ProcessG195 Guide for Conducting Wear Tests Using a RotaryPlatform Abraser2.2 ANSI Standard:B74.12 Checking the Size of Abrasive Grain for GrindingWheels,Polishing,and General Industrial Uses53.Terminology3.1 Definitions:3.1.1 abrasionof resilient floor coverings,a form of wear,in which a gradual removing of a flooring surface is caused bythe frictional action of relatively fine hard particles.3.1.2 resistance to abrasion of resilient floor coverings,the ability of a material to withstand mechanical actions ofrelatively fine hard particles,which by rubbing,scraping,anderoding remove material from a floor covering surface.4.Significance and Use4.1 When subjected to normal in-use traffic conditions,aflooring material is exposed to abrasion caused by the destruc-tive action of fine hard particles.This situation occurs when-ever loose debris,dirt and other particulate matter existsbetween traffic bodies(that is,shoes and a flooring surface).1This test method is under the jurisdiction ofASTM Committee F06 on ResilientFloor Coveringsand is the direct responsibility of Subcommittee F06.30 on TestMethods-Performance.Current edition approved May 1,2014.Published June 2014.Originallyapproved in 1978.Last previous edition approved in 2013 as F51013.DOI:10.1520/F0510_F0510M-14.2This test method is described by W.E.Irwin in“Development of a Method toMeasure Wear on Resilient Flooring,”Journal of Testing and Evaluation,Vol 4,No.1,January 1976,pp.1520.3This grit feed method is frequently referred to as the“Frick Grit Feed Method”because it is based on work done by Otto F.V.Frick as described in“Studies of Wearon Flooring Materials,”Wear,Vol 14,1969,pp.119131.4For 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.5Available from American National Standards Institute,25 West 43rd St.,4thFloor,New York,NY 10036.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Under continuing exposure to an“abrasive action,”a flooringmaterial may suffer a thickness loss sufficient to reduce itsservice life.4.2 Abrasion resistance measurements of resilient floorcoverings can be complicated since the resistance to abrasion isaffected by many factors.These may include the physicalproperties of the
