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.
