Astm Standards for SKI Binding Performance: Environmental Testing of Releasable Ski Bindings

Abstract

This research involves the generation of standards for release bindings used in downhill or “Alpine” skiing. The American Society for Testing and Materials (ASTM) is currently working on voluntary consensus standards for the manufacture of skiing equipment. One aspect under investigation is the effect of specific environments (vibration, contamination and corrosion) on the stability of the functional release characteristics of bindings. The results of the current research indicate that vibration tests affect bindings that have threaded fasteners without any locking provision. The dust and dirt tests affect bindings that rely on a moving boot-binding interface more than those that don't. The salt-fog exposure affected all metallic surfaces. Cast aluminum surfaces were more affected than forged, rolled or drawn surfaces. Stainless steel was relatively unaffected. Bearing surface deterioration was the major factor. Some interaction with boot-binding interfaces did occur. Limits are suggested that differentiate between high and low quality bindings.
