ASTM F473-96

Standard Specification for Binding Mounting Area Dimensions on Alpine Skis and Bindings

SCOPE
1.1 This specification covers  dimensions for binding mounting areas for alpine skis and mounting-related dimensions on alpine ski bindings, in order to optimize the compatibility of the functional unit "ski-binding-retention device-boot." It contains data needed for the manufacture of alpine skis, and for manufacturers of alpine ski bindings, specifically with respect to the binding mounting area. This specification is applicable to alpine skis of the following nominal lengths (see Terminology F472 for the definition of nominal length, L ):  Group 1: LN greater than or equal 1700 mm Group 2: 1400 mm greater than or equal L       1.2 The values stated in SI units are to be regarded as the standard.
