Designation:F355161An American National StandardStandard Test Method forImpact Attenuation of Playing Surface Systems,OtherProtective Sport Systems,and Materials Used for Athletics,Recreation and Play1This standard is issued under the fixed designation F355;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.1NOTEEditorially corrected A1.9 in December 2016.1.Scope1.1 This test method measures the impact attenuation ofsurface systems and materials,specifically the peak impactacceleration(“impact shock”)produced under prescribed im-pact conditions.1.2 This test method is applicable to natural and artificialsurface systems intended to provide impact attenuation,includ-ing natural and artificial turf sports fields.1.3 This test method is applicable to impact attenuatingmats and padding used in sports facilities,including stadiumwall padding,gymnastic mats,wrestling mats,turf playingsystems,pole vault landing systems,playground protectivesurfacing,and other systems.1.4 This test method is used to measure the impact attenu-ation of materials and components used as protective paddingon trampoline frames,goal posts,etc.,provided the material orcomponent can be tested separately from the equipment towhich it is attached.1.5 Without modifications,this test method shall not be usedto test materials and components that are attached to structuresor equipment or finished products,unless the impact attenua-tion of the whole system is of interest.1.6 While it is widely believed that appropriate impactattenuation can reduce the risk of impact-related injuries,therelationships between the results of this test method andspecific injury risk and outcomes have not been determined.1.7 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.8 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:2D1596 Test Method for Dynamic Shock Cushioning Char-acteristics of Packaging MaterialE105 Practice for Probability Sampling of MaterialsE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or ProcessE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodF1292 Specification for Impact Attenuation of SurfacingMaterials Within the Use Zone of Playground EquipmentF2650 Terminology Relating to Impact Testing of SportsSurfaces and Equipment2.2 SAE Standard:SAE J211/1 Instrumentation for Impact Tests-Part 1-Electronic Instrumentation(rev.July 2007)33.Terminology3.1 Definitions of terms related to impact testing of sportssurfaces equipment can be found in Terminology F2650,except as noted.3.2 Definitions:3.2.1 HIC interval,nthe time interval within theacceleration-time history of an impact over which the HICintegral is evaluated.3.2.2 impact,ncontact caused by a moving object(forexample,an impact test missile)striking another object(for1This test method is under the jurisdiction of ASTM Committee F08 on SportsEquipment,Playing Surfaces,and Facilities and is the direct responsibility ofSubcommittee F08.52 on Miscellaneous Playing Surfaces.Current edition approved July 1,2016.Published July 2016.Originally approvedin 1972.Last previous edition approved in 2010 as F355 10a.DOI:10.1520/F0355-16E01.2For 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 SAE International(SAE),400 Commonwealth Dr.,Warrendale,PA 15096-0001,http:/www.sae.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 example,a surface)and during which one or both bodies aresubject to high accelerations.3.2.3 impact test,na procedure in which the impactattenuation of a playground surface or surfacing materials isdetermined by measuring the acceleration of a missile droppedonto the surface.3.2.4 free-fall impact test,nan impact test in which thetrajectory of the missile is not restrained by rails,wires,ormechanisms or structures of any type.3.2.5 guided impact test,nan impact test in which thetrajectory of the missile is restrained by rails,wires,or othermechanism or structure.3.2.6 impact test results,none or more measured orcalculated values from one or more impact tests used to definethe impact attenuation of a playground surface or surfacingmaterials.3.2.7 impact t
