ASTM F473-09

This specification defines the area wherein parts of the binding may be mounted. Standard dimensions and location for a binding mounting area enable a ski designer to locate reinforcing elements within this area. Standard dimensions also enable the binding designer to determine all interface dimensions for binding unit size, screw locations, etc. Bindings and skis built in compliance with this specification are compatible. This specification does not apply to any bindings or skis manufactured prior to Jan. 1, 1979.

1.1 This specification covers dimensions for binding mounting areas for alpine skis and mounting-related dimensions on alpine ski bindings as part of an interface (“ski-binding-boot”) system, in order to optimize the compatibility of the functional elements of the system. 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 chord lengths (see Terminology F 472 for the definition of chord length, L_N):

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
