ISO 8061:2019 pdf download.Alpine ski-bindings — Selection of release torques values
1 Scope
This document specifies methods for the selection of the release torques for alpine ski-bindings. It gives information necessary to determine the release torques recommended for use by ski-binding manufacturers in their instructions for installation and use, and by ski shops for the adjustment of ski- bindings already mounted. It is applicable to state-of-the-art alpine ski bindings. It might be inappropriate for non-mechanical bindings or bindings used with boots which reach more than half-way up the lower leg. This document describes a specified method for the selection of the recommended release torques considering three types of skiers. The method applies to moment-measuring binding test machines, according to ISO 11110.

3.1 release torque
load pattern which leads to a release and which is generated by force(s) acting with a lever arm about a specific axis and with the force sum not being equal to 0
Note 1 to entry: The release moment is defined as the load pattern which leads to a release and which is generated by a force-couple (same magnitude but opposite direction) thus resulting in the force sum being equal to 0. The moment can have x, y and z components.
4 Symbols, notations and coordinates See Figure 1 and Table 1.
6.3.3 The age correction is determined as follows:
— skiers of 9 years of age and under (<10 years): –15 % for M z and M y ;
— skiers who are 50 years or older (≥50 years): –15 % for M z and M y .
6.3.4 Release torque values other than recommended above may be used in the following cases.
a) Skiers who have satisfactory experience with lower settings regarding these recommendations may request settings based on their experience.
b) Skiers who have skiing experience without inadvertent releases may request a setting up to 15 % lower than recommended above.
c) Skiers having certain characteristics like neutral skiing technique, defensive attitude, high degree of control, etc. may request a setting up to 15 % lower than recommended above.
d) Skiers who have experienced inadvertent releases may request a setting up to 15 % higher than recommended above.
6.3.5 Skiers may request settings that are different for twist and forward lean.
6.3.6 If the skier’s style requires greater corrections than indicated above, the skier may change the setting at his own risk.
