ISO 13992:2014

Overview

ISO 13992:2014 - "Alpine touring ski-bindings - Requirements and test methods" defines the principal characteristics, safety requirements and laboratory test methods for alpine touring (randonnée) ski-bindings. The standard applies in principle to bindings for juniors and adults and describes test methods A and B (simple torsion and forward-bending release tests) as examples for evaluating release behavior and safety performance.

Key Topics and Requirements

• Scope and terminology: Defines downhill and walking positions, combined loading, release, release values (torques Mz and My), and limits L1–L4.
• Test methods A & B:
  • Method A: torque applied directly to the sole or ski with a rigidly mounted ski; peak Mz/My recorded.
  • Method B: forces applied to the ski while the sole is mounted on a sensor; peak Mz/My recorded.
• Test conditions:
  • Quasi‑static tests with specified angular velocity (e.g., ~3.8°/s ±0.1°/s for torsion and forward bending).
  • Measurement accuracy requirements (e.g., ±2% above certain torque thresholds).
  • Use of standard test soles and test skis per ISO 9523 / ISO 9838; soles must be cleaned before testing.
• Functional requirements:
  • Bindings must release under torsion (Mz) and forward bending (My) in downhill position.
  • Release behavior in walking position depends on maximum angular displacement.
  • Clear, calibrated release-setting indicator covering manufacturer’s intended range; high settings clearly differentiated (Z = 10 threshold).
  • Visual/function checks, requirement for ski-brake or secure leash attachment.
• Durability and environmental tests: includes reproducibility, energy absorption (recentering), lateral release under impact, field tests, and exposure to corrosion/dirt (with grain-size guidance in annexes).

Applications and Who Uses It

• Manufacturers and designers: to design, validate and mark touring ski-bindings that meet internationally accepted safety and performance criteria.
• Test laboratories and certification bodies: for conducting standardized torsion/forward-bending release tests and conformity assessment.
• R&D and quality assurance teams: for benchmarking binding release behavior, reproducibility and robustness.
• Retailers, rental services and safety regulators: to understand marking, usage limits and safety claims for products.
