Overview
The Tuofeng TFW-313 Intelligent Electromechanical Universal Testing Machine is a high-precision, microprocessor-controlled static mechanical testing system engineered for quantitative evaluation of tensile, compressive, flexural, shear, tear, peel, and puncture mechanical properties across metallic, polymeric, composite, ceramic, and elastomeric materials. Based on the fundamental principles of Hooke’s Law and standardized force-displacement transduction, the system employs a closed-loop servo-controlled electromechanical actuation architecture to deliver repeatable, traceable, and metrologically sound mechanical property data. Designed in strict conformance with international calibration and performance standards—including ISO 7500-1 (Class 0.5), ASTM E4 (Verification of Force-Measuring Systems), and GB/T 16491–2008—the TFW-313 serves as a primary reference instrument for R&D laboratories, QC/QA departments, third-party certification bodies, and regulatory submission workflows requiring documented measurement uncertainty and full auditability.
Key Features
- Full-scale load capacity spanning 0.02 N to 300 kN, supported by dual-range high-stability load cells calibrated to NIST-traceable standards
- Force measurement accuracy of ±0.5% of reading over 0.2–100% of full scale, with 500,000-count A/D resolution and no internal range switching
- High-rigidity dual-column frame with precision-ground ball screws and low-backlash worm gear reducer, enabling smooth, silent, and vibration-damped motion control
- Programmable crosshead speed from 0.001 to 500 mm/min—fully adjustable in real time without mechanical gear changes
- Integrated dual-mode position sensing: optical encoder for gross displacement (±0.005% FS accuracy) and optional clip-on extensometer for true strain measurement (ASTM E83 Class B2 compliant)
- Comprehensive safety architecture: hardware-based emergency stop, programmable electronic limit switches, automatic overload shutdown at 110% of rated capacity, and motorized rapid return function
- Modular fixture interface compatible with standardized wedge-action grips, compression platens, bend fixtures, peel jigs, and custom-designed test tooling per ISO 204, ASTM D638, D790, D1876, and EN ISO 11339
Sample Compatibility & Compliance
The TFW-313 accommodates specimens ranging from sub-millimeter thin films and micro-wires to structural steel coupons and reinforced concrete cores. Its configurable test width (400–600 mm) and extendable stroke (up to 1,200 mm) support standard and non-standard geometries per ASTM D3039 (composites), ISO 527 (plastics), GB/T 228.1 (metals), and JIS Z 2241. All mechanical and software subsystems comply with ISO/IEC 17025 requirements for testing laboratories. Calibration certificates include uncertainty budgets per ISO/IEC 17025:2017 Annex A. The system meets electromagnetic compatibility (EMC) requirements under IEC 61326-1 and carries CE marking for EU conformity. For regulated environments, optional 21 CFR Part 11-compliant software modules provide electronic signatures, audit trails, and role-based access control aligned with FDA GLP/GMP expectations.
Software & Data Management
Tuofeng TestSuite™ v5.2 is a native Windows application supporting multi-language UI (English, Simplified Chinese, Traditional Chinese), SI/imperial unit conversion, and customizable report templates compliant with ISO 14289-1 (PDF/A-1a). The software implements real-time plotting of up to four synchronized axes—including load vs. time, stress vs. strain, displacement vs. time, and load vs. extension—with auto-scaling and cursor-driven delta-value readouts. All raw acquisition data (1 kHz sampling rate, timestamped at microsecond resolution) are stored in open binary+XML format for third-party analysis. Batch processing enables statistical aggregation (mean, SD, CV%, min/max) across multiple specimens. Data export supports CSV, Excel (.xlsx), PDF, and XML schemas compatible with LIMS integration. Firmware and software updates are delivered via secure HTTPS channel with SHA-256 signature verification; lifetime free upgrades included with hardware warranty.

FAQ
What standards does the TFW-313 support out-of-the-box?
The system includes preloaded test methods for ASTM D638, D790, D1876, ISO 527, ISO 178, GB/T 228.1, and JIS Z 2241. Custom method templates can be built using the drag-and-drop test sequence editor.
Is the load cell factory-calibrated and traceable?
Yes—each load cell is individually calibrated against NIST-traceable deadweight standards prior to shipment, with full calibration certificate including uncertainty budget and temperature compensation data.
Can the system perform hold tests at constant load or displacement?
Yes—programmable dwell segments support load-hold, displacement-hold, and strain-hold modes with user-defined duration, tolerance band, and ramp-to-hold transition profiles.
Does the software meet FDA 21 CFR Part 11 requirements?
The base software provides ALCOA+ compliant data integrity. Optional Part 11 Add-On Package adds electronic signatures, audit trail encryption, and permission-based workflow controls validated per GAMP5.
What is the warranty coverage and service response time?
Standard warranty is 24 months parts-and-labor, including on-site calibration verification. Priority technical support offers remote diagnostics within 2 business hours and on-site engineer dispatch within 3–5 business days globally.
