Bone Screw Static Torque Testing Machine

Standard

  • YY/T 0591-2011: Chinese standard specifying torsion testing methods for intramedullary nails, including torque application, angular displacement measurement, and failure criteria.
  • ASTM F1264: International standard covering mechanical testing of intramedullary fixation devices, with protocols for static and quasi-static torsion tests.

Product Advantages

  1. Precision Torsional Control:
    • Electromagnetic servo-controlled torsion system ensures torque application with ±0.1% accuracy, adhering to ASTM F1264’s resolution requirements.
    • Adjustable torque range (0.1–500 Nm) and rotational speed (0.01°–360°/min) for versatile testing scenarios.
  2. Customized Fixturing:
    • Modular torsion clamps with interchangeable collets (6–16mm diameter) and anti-slip mechanisms to accommodate diverse nail diameters and lengths.
    • Specimen alignment guides ensure consistent angular displacement measurements.
  3. Advanced Data Acquisition:
    • Real-time monitoring of torque, angular displacement, and shear modulus with 5000Hz sampling rate.
    • Automatic calculation of key parameters: torsional rigidity (Nm/°), yield torque (Nm), and failure angle (°).
  4. User-Centric Design:
    • Intuitive software with preloaded SOPs for YY/T 0591 and ASTM F1264 compliance.
    • Multi-language interface (English/Chinese/Spanish) and exportable reports (PDF/Excel/CSV).
  5. Durability & Safety:
    • Corrosion-resistant steel frame and overload protection system for long-term reliability.
    • Low-noise operation (<65 dB) suitable for laboratory environments.

Product Features

  • Torque Capacity: 0.1–500 Nm (torsional).
  • Torque Resolution: 0.001 Nm.
  • Angular Accuracy: ±0.01°.
  • Testing Modes:
    • Torsional rigidity (ASTM F1264).
    • Yield torque and failure angle (YY/T 0591).
    • Load-deflection curve analysis.
  • Software Suite:
    • Customizable test profiles with automated pass/fail criteria.
    • 21 CFR Part 11 compliance for audit trails and electronic signatures.
  • Calibration: NIST-traceable certification included, with annual recalibration available.
