Designation:F1936101An American National StandardStandard Specification forImpact Attenuation of Turf Playing Systems as Measured inthe Field1This standard is issued under the fixed designation F1936;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.1NOTEEditorially corrected 8.3 in October 2014.INTRODUCTIONThe impact attenuation of turf playing systems can be measured in a laboratory,but such tests areoften conducted under optimal or tightly controlled conditions.To accurately assess the impactattenuation an athlete will encounter on an installed field,that specific field must be tested in situ.Thatobjective was the impetus for the development of this specification.Initially,the stated scope of thespecification was limited to measuring the impact attenuation of North American football fields.Thescope of the current revision encompasses a broader range of sport-specific field configurations anda protocol for conducting tests on multi-sport fields.1.Scope1.1 This specification establishes an in situ test method andmaximum impact attenuation value for all types of turf playingsystems and for a number of sport-specific field layouts.It alsoincludes a protocol for determining test point locations onfields that are lined for multiple sports.1.1.1 Turf playing systems may be located outdoors orindoors,and typically include field areas within the in-boundslines and areas outside the in-bounds lines extending tosport-specific limit lines;areas where an athlete should expectto encounter impact attenuation performance that complieswith this specification.1.1.2 Site-specific conditions may exist wherein non-turfsurface materials,such as track surfacing and/or covers oversubsurface structures,are found within the boundaries of thelimit lines.These alternate surface materials are not included inthe scope of this specification.1.2 This specification establishes a method for reporting testresults and identifying areas within an existing turf playingsystem where impact attenuation measurements exceed re-quired threshold values.1.3 Nothing in this specification is intended to imposelimitations on what fields can be tested,or how a particularfield can be used.Test providers can adapt the procedures andguidelines contained herein to tests performed on any turfplaying system.1.4 This specification does not imply that an impact-relatedinjury cannot be incurred if a turf playing system complies withits g-max performance requirement.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 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:2F355 Test Method for ImpactAttenuation of Playing SurfaceSystems and MaterialsF1292 Specification for Impact Attenuation of SurfacingMaterials Within the Use Zone of Playground EquipmentF1551 Test Methods for Comprehensive Characterization ofSynthetic Turf Playing Surfaces and MaterialsF1702 Test Method for Measuring Impact-Attenuation Char-acteristics of Natural Playing Surface Systems Using a1This specification is under the jurisdiction of ASTM Committee F08 on SportsEquipment,Playing Surfaces,and Facilities and is the direct responsibility ofSubcommittee F08.65 on Artificial Turf Surfaces and Systems.Current edition approved May 1,2010.Published July 2010.Originally approvedin 1998.Last previous edition approved in 2007 as F1936 071.DOI:10.1520/F1936-10E01.2For 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 Lightweight Portable ApparatusF2650 Terminology Relating to Impact Testing of SportsSurfaces and Equipment2.2 ISO Standard:ISO 6587 Paper,board and pulps Determination of con-ductivity of aqueous extracts3NOTE1Additional references are listed at the end of this specification.3.Terminology3.1 Definitions:Except as noted,definitions in this standardare in accordance with Terminology F2650.3.1.1 abnormal dropany drop of the missile which,due tooperator or equipment problem(s)or uncertainty,results in areading which is questionable.3.1.2 average g-maxsum of the g-max of the second andthird drops divided by two and rounded to the nearest wholenumbe
