Standard Test Method for Snowboard Step-in Bindings

Importancia y uso:

4.1 This test method describes the steps required to evaluate a step-in snowboard binding system function. The test method consists of a series of laboratory tests that evaluate resistance to static and dynamic loading, function under cold and icy conditions, impact and fatigue behavior and assessment of potential false positive release. All tests must be passed.

4.2 All possible strains on the boot can be attributed to one torque M and one force F each on every axis X, Y, Z of a system of coordinates (see Fig. 1). The point of origin of the coordinates is agreed to be in the center of the ankle joint which is located approximately 100 mm from the plantar surface and 80 mm from the back of the heel.

FIG. 1 Torques and Forces

4.3 The torques and forces illustrated in the drawing in Fig. 1 are positive. The corresponding parameters acting in opposite direction are given negative signs. The arrowheads indicate the sense of rotation of the snowboard boot movement.
