Designation:F110704(Reapproved 2015)Standard Terminology Relating toSnowboarding1This standard is issued under the fixed designation F1107;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 terminology covers terms used to describe thegeometry and common hardware used on snowboards(skis),snowboard bindings,and snowboard boots.2.Significance and Use2.1 A standard set of definitions is needed to allowproducers,dealers,users,consumers,general interestindividuals,and consultants to use a common language fordescribing snowboards,snowboard bindings,and snowboardboots.3.Terminology3.1 Definitions(Refer to Figs.1-6):asymmetricalthis refers to a snowboard shape that does nothave a longitudinal line of symmetry.Heel-side and toe-sidesidecuts shaped and offset differently from each other;theyare not mirror images of each other.This typically requiresthat a different snowboard be utilized for regular-foot(leftfoot forward)and goofy-foot(right foot forward)snowboardbinding mounting positions(Fig.5).asymmetrical offset,Os,Ohthe distance along the longitu-dinal axis that each side of an asymmetrical shape is offsetfrom the other side.Offset may be different at the shoulderand heel(Fig.5).chord length(LTS)the straight-line distance between thesnowboard tail and the snowboard tip with the snowboardpressed flat to a plane surface to take out the camber(Fig.2).DISCUSSIONEither method of measurement,at the manufacturersdiscretion,may be used to indicate nominal snowboard length orsnowboard size when rounded to common increment.contact lengththe difference between the projected length,Lp,and the sum of Lt+Lsor Lc=Lp(Lt+Ls)(Fig.1).contact surface areathe product of the average width timesthe contact length expressed quantitatively as follows(Fig.4):Ac5bh12bm1bv4Lc!developed length,LNthe bottom contour length from thesnowboard tip to the snowboard tail,sometimes called thematerial length(Fig.2).edgea sharp,narrow,steel surface that is attached throughoutthe length of the sidecut on the bottom edge of thesnowboard.free bottom camber,Hfthe height of the running surfacefrom a vertical plane surface measured at the highest point,with the snowboard held laterally on edge,free from theeffect of the snowboard weight.heel(of the snowboard)the widest part of the tail section ofthe snowboard(Fig.4).hybrid asymmetricalthis refers to a snowboard shape that isasymmetrical from side to side but symmetrical from tip totail,allowing the same board to be used by both regular-footand goofy-foot riders by reversing the direction of travel,butretaining the non-mirror image sidecut shapes of a fullasymmetrical(Fig.6).inserta reusable,threaded attachment point fixed perma-nently in the snowboard at the time of manufacture,used tomount the bindings to the board.It is typically arranged in apattern corresponding to a particular binding manufacturerspattern.leasha cord-like device wherein one end is attached to thetop surface of the snowboard,or the binding,and the otherend provides an apparatus to attach to one of the riders legs.projected length,Lpthe length of the projection of thesnowboard,measured between the snowboard tip and thesnowboard tail with the snowboard unweighted on a planesurface(unweighted meaning solely under the influence ofits own weight)(Fig.1).running surfacethe entire bottom surface of the snowboardordered by the side geometry.self-weighted bottom camber,Hbthe height of the runningsurface from a plane surface,measured at the highest point,with only the influence of the snowboard weight(Fig.3).1This terminology 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 July 1,2015.Published September 2015.Originallyapproved in 1988.Last previous edition approved in 2010 as F1107 04(2010).DOI:10.1520/F1107-04R15.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 shovel length,Lsthe projected length of the forward turn-up,measured from the tip to the contact point where an 0.1-mmfeeler gage intersects the running surface with the snow-board unweighted on a plane surface(Fig.1).shovel surface areathat surface forward of the shovelcontact point.The shovel contact point is located at Lsfromthe tip.sidecutthat line describing the curved portion of the snow-board contour limited by the lines at the bHand bVdimen-sions and defined by the bottom edge(Fig.4).sidecut geometrythe configuration of the curve borderingthe running surface and defined by the bottom edge(Fig.4).sidecut magnitudethe maximum distance from a line drawnbetween the widest points of the snowboard and the edge ofthe snowboard(Fig.4).snowboard b
