Designation:F60905(Reapproved 2013)An American National StandardStandard Test Method forUsing a Horizontal Pull Slipmeter(HPS)1This standard is issued under the fixed designation F609;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.1.Scope1.1 This test method covers measurement of the slip indexof footwear sole,heel,or related materials on dry walkwaysurfaces in the laboratory and in the field.1.2 The dimensional values used in the test method aregiven in units of inches,pounds,or degrees Fahrenheit.Alternative equivalent values are in parentheses and are forinformational purposes only.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:2E691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodF1646 Terminology Relating to Safety and Traction forFootwear3.Terminology3.1 For definitions of terms,refer to Terminology F1646.4.Significance and Use4.1 The Horizontal Pull Slipmeter3is a laboratory and fieldinstrument designed to provide information about the slipindex characteristics between walkway surfaces and a test footmaterial under dry conditions only.The HPS can not be usedon wet surfaces.Slip index can be affected by surfaceroughness,presence of water,contaminants such as grease andother foreign materials,and floor surface wear over time.Slipindex,as determined by the HPS,most likely will not giveuseful information for evaluating liquid contaminated surfaces,and therefore,will not provide an effective assessment of apotential slipping hazard on a walkway surface under theseconditions.4.2 The value reported by the Horizontal Pull Slipmeter iscalled the slip index.Slip index is ten times the staticcoefficient of friction.For example,a static coefficient offriction of 0.4 is displayed by a slip index of 4.0 whenmeasured by the Horizontal Pull Slipmeter.4.3 The HPS can be used on inclined surfaces.No adjust-ment for slope is needed for measurements in the directionperpendicular to the slope and when averaging four measure-ments at one location taken according to step 10.14.5.Apparatus45.1 Horizontal Pull SlipmeterSee Fig.1.6.Reagents and Materials6.1 Silicon carbide abrasive paper,No.400 grit.6.2 Camel hair brush or other non-static bristle material.7.Test Foot7.1 The test foot shall be Trademark Neolite5Test Liner thatmeasure 0.5 in.(12.7 mm)in diameter and 0.25 in.(6.35 mm)to 0.2 in.(5.08 mm),but not less than 0.2 in.(5.08 mm)inthickness.When testing actual shoe materials,Neolite5shouldbe replaced with the desired test materials.7.2 A set of three test feet of the same material are requiredfor performance of the test.1This test method is under the jurisdiction of ASTM Committee F13 onPedestrian/Walkway Safety and Footwear and is the direct responsibility ofSubcommittee F13.10 on Traction.Current edition approved Sept.1,2013.Published November 2013.Originallyapproved in 1979.Last previous edition approved in 2005 as F609 05.DOI:10.1520/F0609-05R13.2For 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 Horizontal Pull Slipmeter was developed by C.H.Irvine of Liberty MutualInsurance Co.,Hopkinton,MA.4The sole source of supply of the apparatus known to the committee at this timeis C.S.C Force Measurement Inc.,84 Ramah Circle North,Agawam,MA 01001.Ifyou are aware of alternative suppliers,please provide this information to ASTMInternational Headquarters.Your comments will receive careful consideration at ameeting of the responsible technical committee,1which you may attend.Plans forthe instrument may be obtained at a nominal cost from ASTM InternationalHeadquarters.Order ADJ12-606090-47.5Neolite is a registered trademark with Goodyear Tire and Rubber Company.The sole source of supply of the apparatus known to the committee at this time isSmithers Scientific Services,Inc.,425 West Market Street,Akron,OH 44303,withan average specific gravity of 1.27 6 0.02 and an average Shore A hardness of9396.If you are aware of alternative suppliers,please provide this information toASTM International Headquarters.Your comments will receive careful consider-ation at a meeting of the responsible technical committee,1which you may attend.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 8.Calibration8.1 Place the switch button,which is located just
