Four-point Bending Tester
Standard
YY/T 0591 (China): Standard for static four-point bending tests of lockable intramedullary nails.
ASTM F1264 (International): Specifications for evaluating the bending strength and stiffness of surgical fixation devices.
Product Advantages
Dual-Standard Certification: Seamlessly meets both Chinese and international regulatory demands, enabling global market access.
Ultra-Precision Testing: ±0.5% force accuracy and 0.001mm displacement resolution ensure reliable data for R&D and quality control.
User-Centric Design: Intuitive touchscreen interface with multilingual support (English/Chinese/Spanish) and automated test protocols.
Durability: High-grade alloy frame with anti-corrosion coating for long-term stability in laboratory environments.
Safety First: Overload protection, emergency stop, and automatic sample alignment prevent equipment damage and user injury.
Product Features
Four-Point Bending Configuration: Mimics physiological loading conditions to assess nail fatigue resistance and structural integrity.
High-Stiffness Load Frame: Withstands up to 10kN force for testing large-diameter implants.
Dynamic Data Acquisition: Real-time force-displacement curves and stress-strain analysis via integrated software.
Modular Fixture System: Quick-change clamps accommodate varying nail lengths (100–500mm) and diameters (6–14mm).
Customizable Testing Modes: Pre-programmed ASTM/YY protocols plus user-definable parameters for specialized trials.
Compliance Reporting: Automatically generates ISO 17025-ready test certificates with traceable calibration records.
