Designation:G11510(Reapproved 2013)Standard Guide forMeasuring and Reporting Friction Coefficients1This standard is issued under the fixed designation G115;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 guide covers information to assist in the selectionof a method for measuring the frictional properties of materi-als.Requirements for minimum data and a format for present-ing these data are suggested.The use of the suggested reportingform will increase the long-term usefulness of the test resultswithin a given laboratory and will facilitate the exchange oftest results between laboratories.It is hoped that the use of auniform reporting format will provide the basis for the prepa-ration of handbooks and computerized databases.1.2 This guide applies to most solid materials and to mostfriction measuring techniques and test equipment.1.3 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C808 Guide for Reporting Friction and Wear Test Results ofManufactured Carbon and Graphite Bearing and SealMaterialsC1028 Test Method for Determining the Static Coefficient ofFriction of Ceramic Tile and Other Like Surfaces by theHorizontal Dynamometer Pull-Meter MethodD1894 Test Method for Static and Kinetic Coefficients ofFriction of Plastic Film and SheetingD2047 Test Method for Static Coefficient of Friction ofPolish-Coated Flooring Surfaces as Measured by theJames MachineD2394 Test Methods for Simulated Service Testing of Woodand Wood-Base Finish FlooringD2534 Test Method for Coefficient of Kinetic Friction forWax CoatingsD2714 Test Method for Calibration and Operation of theFalex Block-on-Ring Friction and Wear Testing MachineD3108 Test Method for Coefficient of Friction,Yarn to SolidMaterialD3412 Test Method for Coefficient of Friction,Yarn to YarnD3702 Test Method for Wear Rate and Coefficient of Fric-tion of Materials in Self-Lubricated Rubbing ContactUsing a Thrust Washer Testing MachineD4103 Practice for Preparation of Substrate Surfaces forCoefficient of Friction TestingD4917 Test Method for Coefficient of Static and KineticFriction of Uncoated Writing and Printing Paper by Use ofthe Horizontal Plane Method(Withdrawn 2010)3D4918 Test Method for Coefficient of Static Friction ofUncoated Writing and Printing Paper by Use of theInclined Plane Method(Withdrawn 2010)3D5183 Test Method for Determination of the Coefficient ofFriction of Lubricants Using the Four-Ball Wear TestMachineD6425 Test Method for Measuring Friction and Wear Prop-erties of Extreme Pressure(EP)Lubricating Oils UsingSRV Test MachineE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or ProcessE303 Test Method for Measuring Surface Frictional Proper-ties Using the British Pendulum TesterE670 Test Method for Testing Side Force Friction on PavedSurfaces Using the Mu-MeterE1911 Test Method for Measuring Paved Surface FrictionalProperties Using the Dynamic Friction TesterE2100 Practice for Calculating the International RunwayFriction IndexE2101 Test Method for Measuring the Frictional Propertiesof Winter Contaminated Pavement Surfaces Using anAveraging-Type Spot Measuring Decelerometer1This guide is under the jurisdiction of ASTM Committee G02 on Wear andErosion and is the direct responsibility of Subcommittee G02.50 on Friction.Current edition approved Nov.15,2013.Published November 2013.Originallyapproved in 1993.Last previous edition was approved in 2010 as G11510.DOI:10.1520/G0115-10R13.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 F609 Test Method for Using a Horizontal Pull Slipmeter(HPS)F695 Practice for Ranking of Test Data Obtained for Mea-surement of Slip Resistance of Footwear Sole,Heel,andRelated MaterialsF732 Test Method for Wear Testing of Polymeric MaterialsUsed in Total Joint ProsthesesG40 Terminology Relating to Wear and ErosionG77 Test Method for Ranking Resistance of Materials toSliding Wear Using Block-on-Ring Wear TestG99 Test Method for Wear Testing
