Designation:F254607(Reapproved 2012)Standard Test Method forSnowboard Step-in Bindings1This standard is issued under the fixed designation F2546;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 specifies the essential requirements fora snowboard step-in bindingboot system(see 3.1.2);hereaf-ter referred to as step-in snowboard bindings.1.2 This test method is applicable to step-in snowboardbindings for adults and children.This type of binding systemutilizes a mechanical interlocking mechanism,and the inter-lock mechanism of the system will be specific to the particularmanufacturer.Compatibility between different systems is notexpected or anticipated thus each potential combination of bootand binding requires testing.1.3 For snowboard boots interfacing with ski binding,seeISO 11634.1.4 For snowboard plate bindings,see ISO 14790.1.5 For snowboard strap bindings made for soft boots,seeISO 14573.1.6 For snowboard step-in bindings,see ISO 15344.1.7 This standard does not address how or under whatcircumstances a snowboard binding with programmable re-lease modes should release in its intended modes nor does itaddress the safety,desirability,or efficacy of any program-mable release mode for snowboard bindings;any testing ofsuch bindings to this standard must be performed with therelease modes disabled or adjusted to their highest releasevalue.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:2F1107 Terminology Relating to Snowboarding2.2 ISO Standards:3ISO 554:1976 Standard Atmospheres for Conditioningand/or TestingSpecificationsISO 6004 Alpine SkisSki Binding ScrewsRequirementsISO 10958-1 SnowboardsBinding Mounting AreaPart1:Requirements and Test Methods for Snowboards with-out InsertsISO 10958-2 SnowboardsBinding Mounting AreaPart2:Requirements and Test Methods for Snowboards withInsertsISO 11634 Snowboard BootsInterface with Ski BindingISO 14573 Snowboard Strap Bindings for Soft BootsISO 14790 Snowboard Plate BindingsISO 15344 Snowboard Step-in BindingsRequirementsand Test Methods3.Terminology3.1 Definitions:3.1.1 snowboard plate binding for hard bootsa connectingsystem between a hard boot and a snowboard that is accom-plished by means of a plate binding system.For referenceonlynot covered by this test method.3.1.2 snowboard step-in bindingboot systeman inter-locking system that connects a snowboard boot and a snow-board that utilizes a step-in interface.3.1.3 snowboard step-in binding type Abinding suitablefor riders over 45 kg body mass(adults).3.1.4 snowboard step-in binding type Cbinding suitableexclusively for a body mass up to 45 kg(children).1This test method is under the jurisdiction of ASTM Committee F27 on SnowSkiing and is the direct responsibility of Subcommittee F27.30 on Skiing andSnowboarding Equipment.Current edition approved June 1,2012.Published July 2012.Originally approvedin 2006.Last previous edition approved in 2007 as F2546 07.DOI:10.1520/F2546-07R12.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.5 snowboard strap binding for soft bootsa connectingsystem between a soft boot and a snowboard that is accom-plished by means of compression straps or other similardevices.For reference onlynot covered by this test method.3.2 Refer to Terminology F1107 for terminology specific tosnowboarding.4.Testing Parameters4.1 This test method describes the steps required to evaluatea step-in snowboard binding system function.The test methodconsists of a series of laboratory tests that evaluate resistanceto static and dynamic loading,function under cold and icyconditions,impact and fatigue behavior and assessment ofpotential false positive release.All tests must be passed.4.2 All possible strains on the boot can be attributed to onetorque M and one force F each on every axis X,Y,Z of a systemof coordinates(see Fig.1).The point of origin of thecoordinates is agreed to be in the center of the ankle jointwhich is located approximately 100 mm from the plantarsurface and 80 mm from the back of the heel.4.3 The torques and forces illustrated in the drawing in Fig.1 are positive.The cor
