Standard Terminology Relating to Snowboarding
SIGNIFICANCE AND USE
2.1 A standard set of definitions is needed to allow producers, dealers, users, consumers, general interest individuals, and consultants to use a common language for describing snowboards, snowboard bindings, and snowboard boots.
SCOPE
1.1 This terminology covers terms used to describe the geometry and common hardware used on snowboards (skis), snowboard bindings, and snowboard boots.
1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
