Designation:F101503(Reapproved 2009)An American National StandardStandard Test Method forRelative Abrasiveness of Synthetic Turf Playing Surfaces1This standard is issued under the fixed designation F1015;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 is applicable to both laboratory andfield measurement of synthetic turf surfaces used for sports.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.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 appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C421 Test Method for Tumbling Friability of PreformedBlock-Type and Preformed Pipe-Covering-Type ThermalInsulationE105 Practice for Probability Sampling of MaterialsE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or ProcessF355 Test Method for ImpactAttenuation of Playing SurfaceSystems and Materials3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 synthetic turf playing surfacea man-made playingsurface incorporating artificial grass-like fibers.3.1.2 abrasivenessthat property of a synthetic turf whichcauses material in moving contact with the turf surface to wearaway.3.1.3 abrasiveness indexa number equal to the weight lostin grams per foot of travel of a standard weighted friable foamset multiplied by 100,when the foam is pulled through acomplete 1.8-m(6-ft)test cycle.3.1.4 foam friability indexa number equal to the percentmass loss of foam when tested in accordance with theProcedure section of Test Method C421.4.Summary of Test Method4.1 Friable foam blocks are attached to a weighted platformwhich is pulled over the playing surface in a prescribedmanner.The weight of foam abraded away determines therelative abrasiveness of the surface.5.Significance and Use5.1 Data obtained from the procedure of this test method areindicative of the relative abrasiveness of fabric or carpet typesynthetic playing surfaces.6.Apparatus6.1 Abrasiveness Test PlatformA test platform is used tosupport the load on the friable foam material.The platformshall consist of a 20.3 by 20.3 cm(8.00 by 8.00 in.)square of0.635-cm thick(0.25 in.)aluminum.Holes 0.635 cm indiameter shall be centered 0.635 cm from the midpoint of eachedge to permit attachment of a suitable hook for pulling.Foamretaining strips,14in.high by12in.wide,defining 2 by 2-in.squares,are attached at each corner(Fig.1).The completedplatform should weigh 931 6 28 g.6.2 Test WeightA flat-head(9.072-kg(20.00-lb)missileas used in Test Method F355,ProcedureA,can be used as a testweight.A suitable alternative weight is a steel cylinder about15.2 cm(6.00 in.)in diameter and about 6.35 cm(2.50 in.)inheight.The test weight is to be within 56 g(2 oz)of itsspecified weight.6.3 Pull Cable and Direction Changing PulleyA directionchanging pulley attached to an operator foot restraint may beused to facilitate moving the loaded platform across the surfacewhile keeping the pull cable parallel to the surface.The pullcable must not stretch under tension and must be equipped witha method of determining the distance pulled.For example,mechanical stops on either side of the direction changingpulley can be set to give the 45.7-cm(18-in.)pull length.1This test method is under the jurisdiction of ASTM Committee F08 on SportsEquipment,Playing Surfaces,and Facilitiesand is the direct responsibility ofSubcommittee F08.65 on Artificial Turf Surfaces and Systems.Current edition approved July 1,2009.Published August 2009.Originallyapproved in 1986.Last previous edition approved in 2003 as F1015 03.DOI:10.1520/F1015-03R09.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 7.Test Foam37.1 The friable foam blocks used as the test material shall berigid closed-cell isocyanurate foam having a bulk density of0.0312 6 0.0008 g/cm3(1.95 6 0.05 lb/ft3).In addition,thetest foam must have a mass loss of 40 6 2%as measured byTest Method C421.Test blocks must be cut to 5.08 by 5.08 by2.54 cm,0.13 cm(2.00 by 2.00 by 1.00 in.,0.05 in.).8.Test Specimen8.1 Test specimens shall be representative of the playingsurface being evaluated.Fabrics used over a shock-absorbingpad should be tested aft
