1、Designation: F 1107 04Standard Terminology Relating toSnowboarding1This standard is issued under the fixed designation F 1107; 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 indic
2、ates the year of last reapproval. Asuperscript epsilon (e) 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
3、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. 1-6):asymmetrical
4、this 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)
