Overview
The Yuelian YL1125 Universal Testing Machine is an electromechanical static testing system engineered for precision tensile, compression, flexural, and shear property evaluation of metallic, polymeric, composite, and ceramic materials. It operates on a closed-loop servo-controlled load frame architecture with high-stiffness crosshead guidance and precision ball-screw actuation—ensuring repeatable force application and displacement control across the full capacity range (5 kN, 10 kN, or 20 kN). The machine conforms to fundamental metrological standards including ISO 7500-1 (class 0.5 accuracy), GB/T 16491 (Chinese national standard for universal testers), and ASTM E4 (verification of force-measuring instruments), making it suitable for routine QC labs, R&D centers, and third-party certification facilities requiring traceable mechanical test data.
Key Features
- High-rigidity dual-column load frame with preloaded linear guides and reinforced base plate for minimal deflection under peak load
- Digital servo motor drive with real-time PID feedback control enabling precise strain rate regulation (0.001–500 mm/min) and smooth low-speed operation down to 0.005 mm/min
- Integrated load cell with ±0.5% full-scale accuracy (per ISO 7500-1 Class 0.5), temperature-compensated and calibrated to NIST-traceable standards
- Modular extensometer interface supporting clip-on, video, and non-contact options for ASTM E83-compliant strain measurement
- Front-panel touchscreen controller with intuitive menu navigation, real-time curve plotting, and local data storage (USB export)
- Standardized grips and fixtures compliant with ASTM E8 (tensile bars), ASTM D638 (plastics), and ISO 6892-1 (metallic materials)
Sample Compatibility & Compliance
The YL1125 accommodates specimens up to 1,000 mm in gauge length and 300 mm in maximum width, supporting flat, round, and rectangular cross-sections. Its modular jaw design allows rapid interchange between wedge-action, pneumatic, and hydraulic grip systems—enabling secure clamping of brittle, ductile, or soft materials without slippage or premature failure. All test protocols align with internationally recognized material standards: tensile testing per ISO 6892-1 and ASTM E8/E21; compression per ISO 148-1 and ASTM C39/C109; flexure per ISO 178 and ASTM D790. The system supports GLP-compliant audit trails when integrated with optional PC-based software (see Software & Data Management).
Software & Data Management
The YL1125 is compatible with Yuelian’s proprietary TestMaster Pro software (Windows 10/11), which provides full test method configuration, real-time multi-curve overlay, automatic yield point detection (0.2% offset, tangent, or inflection), and standardized report generation (PDF/Excel). The software includes electronic signature support, user-level access controls, and 21 CFR Part 11-compliant audit trail logging—including operator ID, timestamp, parameter changes, and raw data modification history. Raw ASCII data files (.txt) are stored with metadata headers (test ID, date, operator, calibration certificate ID), ensuring full traceability for ISO/IEC 17025 accreditation requirements.
Applications
- Mechanical characterization of structural alloys (e.g., aluminum 6061-T6, stainless steel 304) in aerospace and automotive component validation
- Quality conformance testing of extruded polymer profiles (PVC, ABS, PC) per ISO 527 and ASTM D638
- Compression strength evaluation of concrete cylinders (ASTM C39), mortar cubes (ASTM C109), and foam elastomers
- Adhesion strength assessment of coated substrates (e.g., paint-on-metal, adhesive bonds) using peel and shear fixtures
- Research-grade stress–strain analysis for biomaterials (hydrogels, scaffolds) under controlled environmental conditions (when paired with optional chamber)
FAQ
What load capacities are available for the YL1125 series?
The YL1125 is configured at time of order for one of three nominal capacities: 5 kN (≈510 kgf), 10 kN (≈1,020 kgf), or 20 kN (≈2,040 kgf). Each variant uses a matched load cell and optimized drive tuning.
Is third-party calibration certification included?
Yes—each unit ships with a factory calibration certificate traceable to CNAS-accredited reference standards (equivalent to ISO/IEC 17025). Optional UKAS or NIST-traceable certificates are available upon request.
Can the YL1125 perform cyclic or fatigue testing?
No—the YL1125 is designed exclusively for static and quasi-static tests. For dynamic or high-cycle fatigue applications, consider Yuelian’s dedicated electrodynamic fatigue testing systems (e.g., YL-FAT200 series).
Does the system meet FDA or medical device regulatory requirements?
While not certified as a medical device, the YL1125’s software and documentation package supports compliance with FDA 21 CFR Part 11 when deployed in regulated environments (e.g., ISO 13485-certified implant manufacturers), subject to site-specific validation protocols.
What is the typical lead time for delivery and installation?
Standard units ship within 15 business days after order confirmation. On-site installation, mechanical verification, and basic operator training are included for mainland China deliveries; international shipments require customer-arranged customs clearance and local commissioning support.
