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
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.
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.
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 (°).
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).
Durability & Safety:
Corrosion-resistant steel frame and overload protection system for long-term reliability.
Low-noise operation (<65 dB) suitable for laboratory environments.
