Torque - to - Failure Tester for Metal Bone - connecting Screws

Standard

  • YY/T 0662-2008(Chinese standard for orthopedic implant testing)
  • ISO 5832-1(Metallic materials for surgical implants – Wrought stainless steel)
  • ASTM F543(Standard specification for metallic medical bone screws)
  • ISO 6475(Breaking torque and angle of rotation at failure for metal bone screws)
  • EN ISO 14708-1(Active implantable medical devices – General safety requirements)

Product Advantages

  1. Multi-Standard Compliance: Seamlessly aligns with ASTM, ISO, and EN standards, enabling global market access.
  2. High-Precision Torsional Testing: Capable of measuring breaking torque and rotational angles with ±0.1% accuracy, critical for evaluating screw uniformity.
  3. Versatile Testing Modes: Supports torsional-only and axial-torsional combined loading (up to 17,750 in-lb torque capacity) for comprehensive material characterization.
  4. User-Friendly Interface: Intuitive software with real-time data logging, test customization, and automated report generation (PDF/Excel formats).
  5. Durability: Robust construction with corrosion-resistant components, ideal for repetitive high-load testing in medical device labs.

Product Features

  • Torque Capacity: 62–17,750 in-lb (0.7–2000 Nm), covering small-diameter screws to heavy-duty implants.
  • Rotational Speed: 0.001°–360°/min, adjustable for static or dynamic failure analysis.
  • Axial-Torsional Synchronization: Optional biaxial loading for simulating complex surgical insertion forces (per ASTM F543’s full test suite).
  • Collet-Style Grips: Non-slip, specimen-friendly clamping to prevent premature failure or specimen damage.
  • Biomechanical Simulation: Compatible with rigid polyurethane foam (ASTM F1839) and natural bone substitutes for self-tapping/driving tests.
  • Safety Systems: Emergency stop, overload protection, and automatic specimen ejection.
