Skis alpins -- Mesurage des vibrations en flexion

La présente Norme internationale spécifie une méthode de détermination de la fréquence propre et du temps d'amortissement en flexion d'un ski alpin encastré dans la zone de montage de la fixation, et dont la partie avant est en vibration libre. Elle est applicable aux skis alpins d'une longueur nominale de 150 cm ou plus.

Overview

SIST ISO 6267:1995 - Alpine skis – Measurement of bending vibrations is an international standard published by SIST, adopting ISO 6267. This standard specifies a method for determining the natural frequency and half life of bending vibrations in alpine skis. The procedure is applicable to skis with nominal lengths of 150 cm or more and is intended for manufacturers, testing laboratories, and quality control professionals in the sporting goods industry.

Accurate measurement of bending vibrations is essential for quality assurance and product performance verification of alpine skis. These tests help identify mechanical attributes like flexibility, durability, and user comfort, and contribute to the development of high-performing, reliable ski equipment.

Key Topics

• Definition of Key Terms: The standard defines important parameters such as vibration period (T), natural frequency (f), half life (t1/2), initial deflection, and amplitude, providing a clear framework for consistent measurement and reporting.
• Test Equipment and Setup:
  • Heavy clamping device (≥100 kg) with specific jaw and clamp configurations to ensure secure ski fixation and avoid resonance effects.
  • Release mechanism that induces bending without causing torsional vibrations.
  • Inductive displacement transducer for accurate detection and chart recording of ski vibrations.
• Test Procedure:
  • Skis are conditioned at room temperature (23 ± 5°C) before measurement.
  • The ski is deflected by 2.5 mm at a specified point and released.
  • Vibrations are recorded and evaluated for critical dynamic properties.
• Evaluation and Reporting:
  • Detailed calculation of vibration period, natural frequency, half life, and recording of measurement results.
  • Standardized reporting that includes brand, model, length, and other identification details, ensuring transparency and comparability.

Applications

SIST ISO 6267:1995 is widely used across the sports equipment industry for:

• Product Development: Ski manufacturers use this standard to refine ski designs, maximizing performance characteristics such as flex, stability, and vibration damping.
• Quality Assurance and Compliance: Testing laboratories and quality control teams employ the standard to verify that manufactured skis meet safety and performance specifications.
• Research and Comparative Testing: The method supports comparative testing across brands and models, aiding consumer protection groups and regulatory authorities.
• Certification and Market Access: Compliance with this standard is often required for product certification and international market entry.

Related Standards

For comprehensive testing and evaluation of sports equipment, the following related standards are recommended:

• ISO/TC 83 Standards: Covering sports and recreational equipment, these standards provide further methods for mechanical testing, durability, and safety assessment.
• ISO 11088: Alpine ski/binding/boot systems – Assembly, adjustment, and inspection.
• ISO 6000 Series: General methods for testing the performance of sports equipment.
• ISO 6289: Snowboards and bindings – Measurement and evaluation of mechanical properties.

Summary

SIST ISO 6267:1995 establishes a reliable method for measuring the bending vibrations of alpine skis, contributing to product safety, innovation, and international harmonization in the sporting goods industry. Adopting this standard helps organizations deliver high-quality products and demonstrate compliance with recognized international practices.
