Overview
The Hengyi HY-20080hy Electronic Universal Testing Machine is a high-precision, servo-controlled mechanical testing system engineered for static mechanical characterization of metallic materials. Based on closed-loop electro-mechanical actuation and calibrated force transduction, it adheres to fundamental principles defined in ISO 7500-1 (static calibration of force-proving instruments) and ASTM E4 (load verification of testing machines). Its rigid龙门-frame (double-column) architecture ensures minimal deflection under load, enabling reliable determination of tensile strength, yield strength (upper and lower), Young’s modulus, Poisson’s ratio, elongation at break, reduction in area, and proof stress (e.g., Rp0.2). Designed for compliance with GB/T 228.1–2021, ISO 6892-1:2019, ASTM E8/E8M, and EN 10002-1, the system supports standardized test execution across global metallurgical and industrial R&D environments.
Key Features
- High-fidelity dual-closed-loop control: Independent real-time regulation of load, displacement, and strain—enabling precise stress- or strain-controlled ramping, hold, and cycling protocols.
- Multi-range force measurement capability: Supports interchangeable load cells from 1 N to 200 kN (optional configurations), all traceable to national metrological standards; full-scale resolution of ±500,000 digital counts with no internal range switching.
- Dynamic speed performance: Adjustable crosshead velocity from 0.001 mm/min (for creep/relaxation studies) up to 500 mm/min (for high-throughput screening), with speed accuracy maintained within ±0.5% of setpoint.
- Integrated safety architecture: Dual-stage overload protection (10% over full scale), electronic travel limits, emergency stop circuitry, automatic return-to-start, and programmable termination triggers (force-, displacement-, or time-based).
- Modular extensometry readiness: Compatible with clip-on, video, or non-contact extensometers for high-accuracy strain measurement per ISO 9513 (Class 0.5 or better).
- Self-diagnostic firmware: Continuous monitoring of drive current, voltage, thermal load, and sensor integrity; automatic fault logging and protective shutdown upon anomaly detection.
Sample Compatibility & Compliance
The HY-20080hy accommodates standard metallic specimens per ISO 6892-1 (flat and round tensile bars), ASTM E8 (tension testing of metallic materials), and GB/T 228.1 (metallic materials — tensile testing). Its 600 mm test width and 800 mm vertical stroke support large-section samples—including structural steel plates, aerospace titanium billets, and cast aluminum components—with optional custom fixtures for compression, three-point bending, shear, and peel testing. All hardware and firmware comply with CE Machinery Directive 2006/42/EC, and software functionality meets audit-trail and data integrity requirements aligned with GLP and GMP practices. Calibration certificates are provided with NIST-traceable reference standards, and system validation documentation supports IQ/OQ protocols per ISO/IEC 17025.
Software & Data Management
Bundled with HengyiTest Pro v5.x, the system delivers ISO 17025-compliant data acquisition, visualization, and reporting. The software features real-time multi-curve plotting (stress–strain, force–displacement, load–time), synchronized channel recording (up to 16 analog/digital inputs), and automated calculation of mechanical parameters per user-selected standards. Raw data is stored in encrypted .hdt binary format with embedded metadata (operator ID, timestamp, environmental conditions, calibration status). Export options include CSV, PDF, and XML for LIMS integration. Audit trail functionality logs all user actions—including parameter edits, curve reprocessing, and report generation—with time-stamped, non-erasable records satisfying FDA 21 CFR Part 11 requirements for electronic records and signatures.
Applications
- Metal Production & Quality Assurance: Routine tensile certification of hot-rolled steel coils, cold-drawn stainless wires, extruded aluminum profiles, and nickel-based superalloys used in power generation.
- Aerospace & Automotive Engineering: Mechanical validation of forged landing gear components, welded chassis subassemblies, and additively manufactured Ti-6Al-4V parts under quasi-static loading.
- Research & Development: Constitutive modeling input generation (true stress–true strain curves), fracture toughness pre-cracking support, and high-temperature mechanical behavior evaluation (when paired with environmental chambers).
- Third-Party Certification Laboratories: Accredited testing for ISO/IEC 17025 scope expansion, CE marking support, and supplier qualification audits requiring documented traceability and repeatability (RSD < 1.2% for repeated tensile tests on certified reference materials).
FAQ
What standards does the HY-20080hy comply with for tensile testing?
It fully supports GB/T 228.1–2021, ISO 6892-1:2019, ASTM E8/E8M, EN 10002-1, and JIS Z 2241, with built-in test templates and calculation algorithms aligned to each standard’s clause-specific requirements.
Can the system perform creep or relaxation tests?
Yes—its high-resolution force control (0.005 %FS/s minimum ramp rate) and long-term stability enable ISO 204-compliant uniaxial creep testing and ASTM D2990 relaxation analysis when combined with temperature-controlled enclosures.
Is the software compliant with FDA 21 CFR Part 11?
Yes—HengyiTest Pro implements role-based access control, electronic signatures, immutable audit trails, and secure data export, fulfilling core technical requirements for regulated pharmaceutical and medical device testing environments.
What is the maximum specimen height the machine can accommodate?
The standard effective test space is 800 mm, but the column height and crosshead travel can be extended upon request to accommodate specimens up to 1200 mm tall, subject to structural recalibration.
Does the system support third-party extensometers?
Yes—it provides industry-standard analog (±10 V) and digital (TTL/RS-422) interfaces compatible with major OEM extensometers including Zwick Roell, MTS, and Instron models meeting ISO 9513 Class 0.5 specifications.
