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.
Abstract
Overview
ISO 8061:2019 - "Alpine ski‑bindings - Selection of release torques values" specifies methods to determine recommended release torques for modern alpine ski bindings. It guides ski‑binding manufacturers in publishing installation and use instructions and helps ski shops and fitters adjust mounted bindings. The standard applies to state‑of‑the‑art mechanical alpine bindings and is intended for use with moment‑measuring binding test machines (see ISO 11110). It may be inappropriate for non‑mechanical bindings or boots that extend more than halfway up the lower leg.
Key topics
- Release torque definition and measurement
- Relates the release torque M (Nm) to release force Fr by Fr = Mr / l, where l is the lever arm (m).
- Weight method for torque selection
- Provides formulae to calculate upper and lower limits of release torques for twist (Mz) and forward‑lean (My) releases based on skier mass.
- Coefficients and constants (expressed in m/s² and Nm) are given to derive torque ranges for different mass classes.
- Correction factors
- Skier‑type corrections: Type 1 = −15%, Type 2 = 0%, Type 3 = +15% for both Mz and My (aligned with ISO 11088 practice).
- Age corrections: −15% for skiers
