Yuelian YL-1151 Universal Testing Machine

Overview

The Yuelian YL-1151 Universal Testing Machine is an electromechanical static testing system engineered for high-precision mechanical characterization of metallic and non-metallic materials under uniaxial tensile, compressive, flexural, shear, peel, tear, and adhesion loading conditions. Designed in accordance with international metrological standards—including ISO 7500-1 (static calibration of force-measuring systems) and ASTM E4 (standard practices for force verification of testing machines)—the system employs a closed-loop servo-controlled drive architecture with a precision ground ball screw and timing belt transmission. This ensures exceptional positional repeatability (< ±0.01 mm), minimal backlash, and stable load application across the full speed range (0.5–500 mm/min). The machine is widely deployed in QC laboratories, R&D centers, and third-party certification facilities for mechanical property validation of steel wire ropes, polymer composites, elastomers, textiles, packaging films, aerospace alloys, and structural adhesives.

Key Features

• Modular load frame with rigid welded steel construction and reinforced crosshead guidance for minimal deflection during high-load testing (up to 100 kN)
• Dual-range capacity configuration option enables seamless switching between high-resolution low-force measurements (e.g., peel strength at 1 kN) and high-force structural tests (e.g., steel rope rupture at 100 kN)
• Force transducer calibrated to ISO 7500-1 Class 0.5 accuracy; real-time resolution of 1 part in 500,000 full scale
• Integrated position encoder and digital displacement feedback ensure travel resolution of 1 µm and repeatability within ±0.02% of full stroke
• PC-based control interface with intuitive graphical workflow—supports automated test sequencing, real-time curve overlay, and multi-channel sensor synchronization (e.g., extensometer + load cell + environmental chamber output)
• Comprehensive safety architecture: dual-channel overload cutoff, hardware emergency stop, specimen failure detection via dynamic load drop algorithm, and programmable upper/lower limit stops
• Standard compliance-ready firmware with audit trail logging, user-level access control, and electronic signature support aligned with GLP and FDA 21 CFR Part 11 requirements

Sample Compatibility & Compliance

The YL-1151 accommodates specimens ranging from fine-diameter steel wire ropes (≥0.5 mm) to structural metal coupons (up to 420 mm wide × 1000 mm gage length). Its modular grip system supports wedge-action, pneumatic, hydraulic, and custom-fabricated fixtures for round, flat, or irregular geometries. The system meets mechanical testing requirements specified in ISO 6892-1 (tensile testing of metals), ISO 179-1 (flexural properties of plastics), ASTM D3330 (peel adhesion), ASTM D638 (tensile properties of plastics), and GB/T 228.1 (metallic materials – tensile testing). Calibration certificates traceable to NIM (China National Institute of Metrology) are provided with each unit, and optional UKAS-accredited calibration services are available upon request.

Software & Data Management

The embedded Windows-based test control software provides full IEC 61508-compliant operation with role-based permissions (Administrator, Operator, Reviewer). It supports real-time acquisition from up to four synchronized analog/digital channels, automatic calculation of mechanical parameters—including ultimate tensile strength (UTS), yield strength (Rp0.2), elongation at break, modulus of elasticity, secant modulus, and energy absorption—and export to CSV, PDF, or MS Access databases. All raw data files include embedded metadata: operator ID, timestamp, environmental conditions (if interfaced with external sensors), calibration status, and version-controlled test method templates. Audit logs record every parameter change, test execution, report generation, and user login event—enabling full traceability for ISO/IEC 17025 accreditation audits.

Applications

• Tensile rupture testing of galvanized steel wire ropes per ISO 3154 and ASTM A1023
• Proof load verification and fatigue pre-conditioning of lifting slings and rigging hardware
• Interfacial bond strength evaluation of fiber-reinforced polymer (FRP) tendons and concrete substrates
• Peel resistance quantification of pressure-sensitive adhesives used in medical device packaging (ASTM D903)
• Mechanical screening of thermoplastic elastomer extrusions for automotive sealing applications
• Compression testing of cellular polymeric foams per ISO 844 and ASTM D1621
• Flexural stiffness assessment of composite laminates per ISO 14125 and ASTM D790

FAQ

What standards does the YL-1151 comply with for force calibration?

The system is factory-calibrated per ISO 7500-1 Class 0.5 and includes a NIM-traceable certificate. Optional UKAS or DAkkS-certified recalibration services are available.
Can the machine perform cyclic or fatigue testing?

No—the YL-1151 is designed exclusively for static mechanical testing. For dynamic or high-cycle fatigue applications, we recommend our YL-FAT series servo-hydraulic systems.
Is the software compatible with LIMS integration?

Yes—via configurable ODBC drivers and XML-based result export, enabling direct ingestion into LabVantage, Thermo Fisher SampleManager, or custom LIMS platforms.
What is the warranty coverage and service response time?

Standard 24-month parts-and-labor warranty; on-site technical support available within 72 business hours in Tier-1 Chinese cities and major EU/US industrial hubs.
Does the system support extensometer interfacing?

Yes—both clip-on and non-contact video extensometers (e.g., QMAT series) can be integrated via analog voltage input or digital TTL trigger signals.
