Jianhu DV-UTM Series High-Precision Universal Testing Machine

Overview

The Jianhu DV-UTM Series High-Precision Universal Testing Machine is an electromechanical testing platform engineered for static mechanical characterization of materials under tension, compression, bending, and shear loading conditions—across ambient, elevated, or sub-ambient temperature environments. Based on servo-controlled linear actuation and high-fidelity multi-channel data acquisition, the system implements standardized quasi-static mechanical testing per ISO 6892-1 (tensile), ISO 178 (flexural), ISO 604 (compressive), and ASTM D638/D790/D695 protocols. Its modular architecture integrates dual-range load cells, optical extensometry, and real-time closed-loop control—enabling traceable, repeatable, and auditable measurement of fundamental mechanical properties including yield strength, ultimate tensile strength, Young’s modulus, Poisson’s ratio, r-value, elongation at break, and stress relaxation behavior.

Key Features

• Dual high-accuracy load cells (1 kN and 50 kN) certified to ISO 7500-1 Class 0.5 and ASTM E4, delivering ±0.3% accuracy in mid-to-high load ranges and ±0.5% down to 1 N—ensuring metrological integrity across six decades of force measurement.
• High-stiffness frame (180 kN/mm) with integrated automatic deflection compensation algorithm, minimizing parasitic deformation effects during high-load testing and maintaining alignment fidelity per ASTM E1012 Class 10 requirements.
• Optical extensometer with ≥500 mm field of view, ±0.5% strain resolution, and synchronized high-speed video capture—supporting non-contact measurement of local strain, Poisson’s ratio, and r-value without grip interference.
• Ultra-broad crosshead speed range (0.0005–1500 mm/min) with ±0.1% speed accuracy, enabling both creep/relaxation tests and high-rate quasi-static evaluations within a single platform.
• Real-time data acquisition at up to 10,000 samples per second across force, displacement, and extensometer channels—preserving full waveform fidelity for post-test derivative analysis (e.g., strain rate sensitivity, hysteresis loops).
• Modular fixture interface compatible with pneumatic, hydraulic, wedge-grip, pin-and-hole, and custom tooling—supporting standardized geometries (ASTM E8, ISO 6892) as well as application-specific specimen configurations.

Sample Compatibility & Compliance

The DV-UTM accommodates specimens ranging from micro-scale polymer films (≥10 µm thickness) to structural metallic coupons (up to 300 mm gauge length), including ductile metals, thermoplastics, elastomers, composites, ceramics, hydrogels, textiles, and biomedical polymers. It supports environmental chamber integration (−70°C to +300°C) for temperature-dependent mechanical profiling. All measurement outputs comply with GLP/GMP documentation requirements, including audit-trail-enabled test logs, electronic signatures, and 21 CFR Part 11–compliant software configuration. Calibration certificates are traceable to NIM (National Institute of Metrology, China) and internationally recognized national metrology institutes.

Software & Data Management

Jianhu TestSuite™ v5.2 provides ISO/IEC 17025-aligned test sequencing, real-time parameter monitoring, and automated report generation per ASTM/ISO templates. The interface supports multiple control modes—including constant crosshead speed, constant strain rate, constant stress rate, and load-controlled ramp-hold sequences—with seamless switching during active tests. Raw binary data (force/displacement/strain/time) is exported in ASCII-compatible .csv and standardized .tdms formats for third-party analysis (MATLAB, Python, Minitab). All user actions, calibration events, and instrument state changes are logged with timestamped audit trails. Software validation packages—including IQ/OQ documentation—are available upon request for regulated industries (pharmaceuticals, medical devices, aerospace).

Applications

The DV-UTM serves as a core instrumentation platform in R&D laboratories, QC/QA departments, and accredited testing facilities. Typical use cases include: tensile evaluation of PCB substrates per IPC-TM-650 2.4.1; cyclic extension testing of hydrogels for tissue engineering scaffolds; determination of elastic modulus and Poisson’s ratio in PET thin films per ISO 527-2; multi-point tensile characterization of carbon-fiber-reinforced polymers (CFRPs); and strain-rate-dependent yield mapping of aluminum alloys per ASTM E2234. It is routinely deployed in academic institutions (e.g., Tsinghua University, Harbin Institute of Technology), national research centers (CAS Institutes), and global certification bodies (SGS, Bureau Veritas).
