1、Designation: F473 09 (Reapproved 2017)Standard Specification forBinding Mounting Area Dimensions on Alpine Skis andBindings1This standard is issued under the fixed designation F473; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, t

2、he year of last revision. A number in parentheses indicates the year of last reapproval. A superscriptepsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers2dimensions for bindingmounting areas for alpine skis and mounting-related dimen-s

3、ions on alpine ski bindings as part of an interface (“ski-binding-boot”) system, in order to optimize the compatibilityof the functional elements of the system. It contains dataneeded for the manufacture of alpine skis, and for manufac-turers of alpine ski bindings, specifically with respect to theb

4、inding mounting area. This specification is applicable toalpine skis of the following chord lengths (see TerminologyF472 for the definition of chord length, LN):Group 1: LN$ 1700 mmGroup 2: 1400 mm # LN 1700 mmGroup 3: 1000 mm # LN 1400 mmGroup 4: 750 mm # LN 1000 mm1.2 The values stated in SI units

Terminology3.1 Definitions:3.1.1 binding mountingall the connections between theparts of the binding and the ski, especially those designed totransmit forces between binding and ski and that fulfill theminimum strength requ

8、irements determined for the function ofthe binding.3.1.2 binding mounting areathat portion of the top surfaceof the ski that is intended for mounting bindings. The stan-dardized binding mounting area establishes the area on the skiwithin which the entire diameter of binding screws should beplaced.4.

9、 Significance and Use4.1 This specification defines the area wherein parts of thebinding may be mounted. Standard dimensions and location fora binding mounting area enable a ski designer to locatereinforcing elements within this area. Standard dimensions alsoenable the binding designer to determine

10、all interface dimen-sions for binding unit size, screw locations, etc. Bindings andskis built in compliance with this specification are compatible.This specification does not apply to any bindings or skismanufactured prior to Jan. 1, 1979.5. Specifications of Binding Mounting Area5.1 TolerancesUnles

11、s otherwise indicated, the toleranceon all dimensions specified is 61 mm.5.2 Indication of Mounting Point:5.2.1 The ski manufacturer shall be required to put a clearlyvisible mark at least on the left side or top surface, or both, ofthe ski, up to the left outer edge. This line corresponds with them
