Standard

ASTM F2119: Standard test method for constant load testing of bioabsorbable screws and washers, applicable to bending performance evaluation.
ISO 10993-1: Biological evaluation of medical devices, ensuring compatibility with biodegradable material testing.
YY/T 0342: Chinese standard for bending strength and stiffness testing of metallic bone plates (adapted for bioabsorbable materials).

Biodegradable Material Expertise:
- Optimized for polymers (PLA, PGA) and composites, with adjustable test parameters to accommodate degradation-induced property changes.
- Environmental control options (37°C ± 2°C, pH-regulated media) for simulating in-vivo conditions.
Precision Four-Point Bending:
- Electromagnetic load frame with ±0.1% force accuracy, ensuring compliance with ASTM F2119’s resolution requirements.
- Adjustable span ratios (10:1 to 20:1) for tailored stress distribution analysis.
Advanced Data Acquisition:
- Real-time monitoring of force, displacement, and bending modulus with 5000Hz sampling rate.
- Automatic calculation of key parameters: bending strength (MPa), flexural modulus (GPa), and strain-at-break.
User-Centric Design:
- Intuitive software with preloaded SOPs for ASTM F2119 and ISO 10993-1 compliance.
- Multi-language interface (English/Chinese/Spanish) and exportable reports (PDF/Excel/CSV).
Durability & Safety:
- Corrosion-resistant components and overload protection system for long-term reliability.
- Low-noise operation (<65 dB) suitable for laboratory environments.

Load Capacity: 5 kN (axial) / 250 Nm (torsional).
Force Resolution: 0.001 N (axial) / 0.0001 Nm (torsional).
Displacement Accuracy: ±0.1 μm.
Testing Modes:
- Bending stiffness (ASTM F2119).
- Bending strength (YY/T 0342 adaptation).
- Creep testing (constant load over time).
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.
