Designation:F277211An American National StandardStandard Specification forAthletic Performance Properties of Indoor Sports FloorSystems1This standard is issued under the fixed designation F2772;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 specification establishes levels for athletic perfor-mance properties of multi-purpose indoor sports floor systemsexcluding turf and materials specific to running tracks andtennis courts.1.2 The methods described are applicable in both thelaboratory and field unless otherwise stated.1.3 UnitsThe values stated in inch-pound units are to beregarded as the standard.The values given in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered standard.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:2E303 Test Method for Measuring Surface Frictional Proper-ties Using the British Pendulum TesterF2117 Test Method for Vertical Rebound Characteristics ofSports Surface/Ball Systems;Acoustical MeasurementF2157 Specification for Synthetic Surfaced Running TracksF2569 Test Method for Evaluating the Force ReductionProperties of Surfaces for Athletic Use2.2 Other Standards:3EN 13036-4 Road and Airfield Surface Characteristics.TestMethods.Method for Measurement of Slip/Skid Resis-tance of a Surface.Part 4:The Pendulum Test.ISO48 RubberVulcanizedorThermoplasticDetermination of Hardness(hardness between 10 IRHDand 100 IRHD)ISO4662 RubberVulcanizedorThermoplasticDetermination of Rebound Resilience3.Terminology3.1 Definitions:3.1.1 area-elastic,adjdescribes sports floors having arigid upper layer(for example,wood)supported by resilientcomponents.3.1.2 combination-elastic,adjdescribes floors having apoint elastic upper layer in combination with a rigid structurallayer(for example,wood,high-density composites,pourednonresilient materials)and resilient support components(forexample,elastic pads,foam blanket,or poured urethane).3.1.3 point-elastic,adjdescribes sports floors that are onlycomprised of an elastic layer or layers(for example,surfacessuch as poured urethanes,vinyl,or rubber sheet goods).4.Classification4.1 Compliance with the properties contained in this speci-fication shall be determined based on the values designated inSection 4 of this specification.4.1.1 The field test shall clearly indicate the average andmaximum and minimum values for general comparison toperformance of laboratory samples.4.2 Force ReductionIn the case of force reduction,twoparameters are required:4.2.1 Performance LevelFor laboratory samples,the av-erage performance of all test points shall achieve a level asindicated in Table 1.If no performance level is met,the resultstated in the report shall be“No Performance LevelAchieved.”4.2.2 UniformityLaboratory samples shall be such that theforce reduction value of every individual test point falls withina spread of 65.0 percentage points of the average of all testpoint values.The report shall be marked“Noncompliant”ifany individual test point does not meet this requirement.4.3 Ball ReboundIn the case of ball rebound,two param-eters are required:4.3.1 Performance LevelFor laboratory samples,the av-erage performance of all test points shall achieve a minimum of1This 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 Nov.1,2011.Published December 2011.Originallyapproved in 2009.Last previous edition approved in 2009 as F2772 09.DOI:10.1520/F2772-11.2For 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 American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 90%as indicated in Table 2.If the performance level is notmet,the result stated in the report shall be“Performance LevelNot Achieved.”4.3.2 UniformityLaboratory samples shall be such that theball rebound value of every individual test point falls within aspread of 63.0 percentage points of the average of all test pointvalues.The report shall be marked“Noncompliant”if anyindividual test point does not meet this requir
