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.

Standard Terminology Relating to
Snowboarding
This standard is issued under the fixed designation F1107; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
