(Specification)Standard Specification for Static Screw-Retention Strength of Binding Mounting Area on Alpine Skis (Withdrawn 2004)
Standard Specification for Static Screw-Retention Strength of Binding Mounting Area on Alpine Skis (Withdrawn 2004)
SCOPE
1.1 This specification covers the determination of the attachment strength of bindings to alpine skis. This specification is applicable to alpine skis of the following nominal lengths (see Terminology F 472 for a definition of nominal length lN):Group 1:LN 1700 mmGroup 2:1400 mm L N 1700 mmGroup 3:1000 mm L N 1400 mmGroup 4:750 mm L N 1000 mm
1.2 The binding mounting area, a designated binding attachment area provided by the ski manufacturer in accordance with Specification F 473, shall be the only area of the ski subjected to this test and may be specially reinforced.
1.3 This specification covers skis in which bindings are attached by means of screws.
1.4 The specified tests check tendencies for screws to pull out, skis to delaminate, and screw hole threads to strip by using test screws that are loaded normal to the ski surface.
1.5 The following precautionary statement pertains only to the test method portion, Section 6, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This specification covers the determination of the attachment strength of bindings to alpine skis.
This specification is being withdrawn due to lack of interest and support for continued use.
Formerly under the jurisdiction of Committee F27 on Snow Skiing, this specification was withdrawn in April 2004.
