Overview
The Hengyi HY-3080TUNBN is a dual-column electromechanical universal testing machine engineered for high-reproducibility mechanical characterization of wire and cable materials—specifically designed to meet the stringent requirements of GB/T 2951, IEC 60811, ASTM D412, ISO 37, and UL 1581 standards. Its modular load frame architecture supports static tensile, compression, flexural, peel, tear, puncture, and shear testing modes under closed-loop displacement, load, or strain control. The system employs a precision ball-screw-driven crosshead with servo-motor actuation and integrated digital force transduction, enabling traceable force measurement across 15 selectable capacity ranges—from 1 N to 30 kN—without mechanical range switching. All force sensors are factory-calibrated per ISO 7500-1 Class 0.5, ensuring compliance with GLP/GMP documentation requirements for regulated laboratories.
Key Features
- Dual-column rigid steel frame with 700 × 400 × 1600 mm footprint and 800 mm usable test height—optimized for vertical alignment of elongated cable specimens and compliant with ISO 20413 mounting guidelines.
- High-resolution force measurement system: ±500,000 internal counts at full scale, maintaining constant resolution across the entire 0.1–99.999% FS dynamic range—no auto-ranging artifacts or step changes in sensitivity.
- Programmable speed control from 0.001 to 1000 mm/min with ±0.5% linearity, supporting both quasi-static ASTM D882-compliant creep tests and high-rate rupture analysis per IEC 60227-2.
- Integrated safety architecture: electronic end-of-travel limits, hardware-based 110% overload cutoff, real-time diagnostic monitoring of drive current, voltage, and thermal load—meeting EN ISO 12100 functional safety principles.
- Intuitive manual and automated operation: motorized crosshead with fast/slow jog modes, programmable return-to-start, and multi-condition termination (e.g., fracture detection via load drop, preset extension, elapsed time).
- Modular sensor compatibility: supports interchangeable load cells (1 N–30 kN), extensometers (contact/non-contact), and environmental chambers (−70°C to +300°C) without frame modification.
Sample Compatibility & Compliance
The HY-3080TUNBN accommodates standardized dumbbell, strip, and cord-type specimens per GB/T 2951.12–2008 (polymeric insulations and sheaths) and IEC 60811-501 (tensile strength and elongation at break). Its 380 mm test width and adjustable grip spacing enable evaluation of stranded conductors, armored cables, fiber-optic buffer tubes, and extruded polymer jackets—including thermoplastics (PVC, PE, TPE), thermosets (XLPE, EPR), and halogen-free flame-retardant compounds (LSZH). The system meets mechanical verification requirements of ISO 7500-1, calibration traceability to NIM (National Institute of Metrology, China), and supports audit-ready records for CNAS, FDA 21 CFR Part 11 (when paired with compliant software), and EU Machinery Directive 2006/42/EC conformity assessment.
Software & Data Management
Bundled Hengyi TestMaster v4.2 software provides ISO/IEC 17025-aligned test sequence definition, real-time curve overlay, and automated report generation in PDF/XLS formats—including ASTM/ISO-compliant parameter extraction (tensile strength, yield point, modulus at 100%/300%, elongation at break, permanent set). Raw data export supports third-party statistical analysis (Minitab, JMP) and LIMS integration via ASTM E1382-compliant ASCII output. Audit trail functionality logs user actions, method changes, calibration events, and result modifications—fully compliant with FDA 21 CFR Part 11 when configured with electronic signatures and role-based access control.
Applications
- Wire & cable QC: tensile strength and elongation testing of insulation (PVC, XLPE) and jacketing (CPE, CSPE, TPU) per GB/T 2951.14 and UL 1581 Section 1060.
- R&D validation: stress–strain profiling of novel polymer blends, nanocomposite sheaths, and recycled HDPE cable jackets under controlled temperature/humidity.
- Failure analysis: determination of brittle-to-ductile transition in low-temperature cable materials per IEC 60811-1-3.
- Quality assurance in Tier-1 automotive harness production: peel strength of adhesive-laminated shielding tapes and crimp joint integrity verification.
- Regulatory submission support: generating mechanically validated datasets for CCC, CE, and UL certification dossiers.
- Cross-industry use: textile filament tensile testing (ISO 2062), geotextile tensile strength (GB/T 15788), and pharmaceutical blister foil peel resistance (ASTM F88).
FAQ
What standards does the HY-3080TUNBN directly support for wire and cable testing?
It natively implements test routines for GB/T 2951 series, IEC 60811-501, ASTM D412, ISO 37, and UL 1581—covering tensile strength, elongation at break, and modulus calculation.
Can the system perform simultaneous multi-axis mechanical testing?
No—it is a uniaxial static testing platform. Biaxial or torsional loading requires separate specialized systems.
Is third-party calibration certification included with delivery?
Yes—a NIM-traceable calibration certificate (ISO/IEC 17025 accredited) is provided for force, displacement, and speed channels at time of shipment.
What is the maximum specimen length it can accommodate?
With standard configuration, specimens up to 800 mm gauge length may be tested; extended-height options increase this to 1200 mm upon request.
Does the machine support high-speed video synchronization for deformation analysis?
Yes—via TTL-triggered external camera input (GigE Vision compatible), enabling digital image correlation (DIC) integration for full-field strain mapping.
