Four - point Bending Tester
Standard
YY/T 0342-2022: Chinese standard specifying methods for determining bending strength and equivalent bending stiffness of straight and pre-angled metallic bone plates.
ASTM F382: International standard covering mechanical testing, dimensional requirements, and reporting protocols for metallic bone plates.
Product Advantages
High-Precision Force Application:
Electromagnetic load frame with ±0.1% accuracy, ensuring compliance with YY/T 0342’s force resolution requirements.
Adjustable test speed (0.001–500 mm/min) for static and quasi-static loading.
Customizable Fixturing:
Modular four-point bending clamps with interchangeable roller diameters (6–13mm) and contour-matching designs to accommodate straight, angled, and pre-curved bone plates.
Anti-slip mechanisms and specimen alignment guides for consistent results.
Advanced Data Acquisition:
Real-time monitoring of force, displacement, and bending stiffness with 5000Hz sampling rate.
Automatic calculation of key parameters: bending strength (MPa), equivalent stiffness (N/mm), and yield points.
User-Centric Design:
Intuitive software with preloaded SOPs for YY/T 0342 and ASTM F382 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.
