1、Designation: F1107 04 (Reapproved 2010)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 p
2、arentheses 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
3、. Significance and Use2.1 A standard set of definitions is needed to allow produc-ers, dealers, users, consumers, general interest individuals, andconsultants to use a common language for describing snow-boards, snowboard bindings, and snowboard boots.3. Terminology3.1 Definitions (Refer to Figs. 1-
4、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 (le
5、ftfoot 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 le
