Overview
The Yuelian YL-1125 Universal Tensile Testing Machine is an electromechanical materials testing system engineered for precision mechanical property evaluation across a broad spectrum of industrial and research applications. Based on the fundamental principles of uniaxial force-displacement measurement under controlled strain or load rates, the YL-1125 complies with standardized test methodologies defined in ASTM E8/E8M (tension), ASTM D638 (plastics), ASTM D3039 (composites), ISO 6892-1 (metallic materials), ISO 527 (plastics), and GB/T 228.1 (Chinese national standard for metallic tensile testing). Its rigid frame architecture—constructed from high-stiffness steel components—and precision-ground ball screw drive ensure minimal deflection and high axial alignment stability during high-force testing up to 50 kN. The system integrates a high-resolution load cell with 1/250,000 internal resolution and certified force accuracy of ≤ ±0.5% of reading, enabling reliable determination of yield strength, ultimate tensile strength, elongation at break, Young’s modulus, Poisson’s ratio, and other critical mechanical descriptors.
Key Features
- Modular load capacity selection ranging from 10 N to 50 kN, including optional dual-range configurations for enhanced low-load sensitivity and high-force robustness within a single platform
- Servo-motor-driven crosshead with synchronous timing belt and preloaded precision ball screw transmission, delivering smooth motion control and repeatability across the full speed range (0.5–500 mm/min)
- Programmable safety logic: overload protection, emergency stop circuitry, automatic halt upon specimen fracture, user-defined upper/lower displacement or force limits, and post-test automatic return to home position
- High-precision position feedback system with 0.005 mm travel resolution, supporting accurate strain measurement and compliance with ISO 527-2 extensometer requirements when paired with optional contact or non-contact extensometers
- Full PC-based control interface with intuitive graphical workflow navigation, real-time data streaming, and synchronized multi-channel acquisition (load, displacement, optional extensometer, environmental sensor inputs)
- Integrated power management and thermal stabilization design ensures stable performance during extended-duration creep or cyclic loading tests
Sample Compatibility & Compliance
The YL-1125 accommodates specimens from diverse material classes—including elastomers, thermoplastics, thermosets, metals, composites, textiles, paper, leather, adhesives, and photovoltaic laminates—using interchangeable grip systems (pneumatic, wedge, hydraulic, or custom fixtures). Its 420 mm test width and 1000 mm vertical stroke support large-format solar panel substrates, composite laminates, and structural polymer profiles. All hardware and firmware comply with CE marking directives (2006/42/EC Machinery Directive, 2014/30/EU EMC Directive) and meet electromagnetic compatibility requirements per EN 61326-1. The system supports audit-ready operation under GLP and GMP environments through configurable user access levels, electronic signature capability, and optional 21 CFR Part 11-compliant software modules for regulated industries.
Software & Data Management
The proprietary YL-TestSuite software provides a modular, Windows-based environment compatible with Windows 10/11 (64-bit) and MS Access database integration. It enables automated test sequence definition, real-time curve overlay, statistical batch reporting, and export to CSV, PDF, XML, or Excel formats. Core analytical functions include automatic yield point detection (0.2% offset method), tangent modulus calculation, hysteresis loop analysis, and stress-strain normalization. Multi-sensor synchronization allows concurrent recording of load, displacement, temperature, humidity, or video feed (via optional USB camera integration). Audit trails log all user actions, parameter changes, and calibration events with timestamps and operator IDs—essential for ISO/IEC 17025-accredited laboratories.
Applications
- Photovoltaic module qualification: peel strength of EVA/glass/backsheet interfaces, tensile integrity of busbar ribbons, and bending fatigue resistance of framed solar panels
- Automotive component validation: tensile strength of seatbelt webbing, shear resistance of bonded trim layers, and compression resilience of foam padding
- Packaging R&D: seal strength of flexible laminates, puncture resistance of corrugated board, and tear propagation in multilayer films
- Aerospace material certification: tensile properties of carbon-fiber prepregs, interlaminar shear strength (ILSS) via short-beam testing, and adhesive bond durability under thermal cycling
- Quality assurance in wire & cable manufacturing: conductor tensile elongation, insulation jacket peel adhesion, and crimp joint pull-out force verification
- Academic and governmental research labs conducting fundamental studies on viscoelasticity, fracture mechanics, and time-dependent deformation behavior
FAQ
What standards does the YL-1125 support for solar panel material testing?
The system implements test protocols aligned with IEC 61215-2 (photovoltaic module qualification), UL 1703 (flat-plate PV modules), and ASTM D903 (peel resistance), with customizable test templates for backsheet adhesion, junction box pull strength, and frame anchorage evaluation.
Can the YL-1125 be integrated into an existing LIMS or MES environment?
Yes—via OPC UA or TCP/IP API interfaces, the controller supports bidirectional data exchange with laboratory information management systems (LIMS) and manufacturing execution systems (MES), enabling automated job dispatch, result ingestion, and electronic batch record generation.
Is calibration traceability provided with the system?
Each load cell is supplied with a UKAS-accredited calibration certificate (ISO/IEC 17025) valid for 12 months, and the system includes built-in calibration verification routines using NIST-traceable reference weights and displacement gauges.
What extensometer options are compatible with this machine?
The YL-1125 accepts both clip-on axial extensometers (e.g., 10–50 mm gauge length, ±0.5% accuracy) and non-contact digital image correlation (DIC) systems for full-field strain mapping, with native driver support in YL-TestSuite.
Does the software support multi-language UI and report generation?
The interface supports English, German, French, Spanish, and Simplified Chinese; reports can be generated in any selected language with configurable header/footer branding, regulatory disclaimer footers, and digital signature fields.
