Overview
The Yuelian YL-S70 Computer-Controlled Universal Tensile Testing Machine is an electromechanical materials testing system engineered for precision mechanical characterization in R&D laboratories, quality control environments, and manufacturing validation settings. Designed in compliance with Chinese national standard GB/T 2792—specifically addressing peel strength, adhesion, and interfacial bond integrity—it extends functionality beyond peel testing to encompass tensile, compression, flexural (3-point and 4-point), shear, tear, puncture, and cyclic loading protocols. The system operates on a closed-loop servo-controlled architecture, utilizing an AC servo motor coupled to a high-precision ground ball screw transmission assembly. This configuration ensures exceptional positional repeatability, minimal backlash, and stable velocity control across its full 0.001–500 mm/min range. Force measurement is performed via a calibrated dual-polarity load cell, supporting both tension and compression modes without hardware reconfiguration. All mechanical, electrical, and software subsystems are integrated into a unified platform compliant with fundamental metrological traceability principles outlined in ISO/IEC 17025 and aligned with functional requirements referenced in ASTM E4, ISO 7500-1, and GB/T 16491.
Key Features
- Modular mechanical design with quick-release fixture interfaces enabling rapid tooling changes for diverse specimen geometries and test types.
- Aluminum extrusion beam housing with sandblasted and anodized silver finish; ABS polymer enclosure with electrostatic powder coating for corrosion resistance and long-term dimensional stability.
- Dual-limit micro-switches for fine stroke adjustment and precise zero-position calibration.
- Comprehensive safety architecture: hardware-based overtravel cutoff, electronic overload shutdown, emergency stop circuitry meeting IEC 60204-1 requirements, and software-enforced upper/lower bound constraints.
- High-fidelity data acquisition at 2000 samples per second, synchronized across force, displacement, and time channels with sub-micrometer resolution (1/500,000 mm).
- Full bidirectional force transduction capability—no recalibration required when switching between tensile and compressive loading configurations.
Sample Compatibility & Compliance
The YL-S70 accommodates specimens ranging from thin films and adhesive tapes (per GB/T 2792 peel standards) to rigid polymers, elastomeric foams, metallic strips, composite laminates, and footwear components. Its Ø140 mm test chamber and 450 mm effective stroke support standardized dumbbell-shaped tensile bars (ASTM D638, ISO 527), flexural beams (ASTM D790, ISO 178), and custom fixtures for shoe sole puncture (GB/T 3903.3) or corrugated box compression (ISO 12048). The system supports audit-ready operation under GLP and GMP frameworks through configurable user access levels, electronic signature support, and optional 21 CFR Part 11–compliant software modules. All force sensors are factory-calibrated against NIST-traceable reference standards, with certificate-of-calibration provided upon delivery.
Software & Data Management
The embedded Windows-based control software provides full test method scripting, real-time visualization, and post-test analytics. Users define multi-segment test profiles—including ramp-hold-relax cycles, rate transitions, and conditional termination logic—with up to seven independent intervals per method. Graphical overlays allow side-by-side comparison of historical datasets; curve navigation includes zoom, pan, crosshair cursor, and point extraction. Statistical reporting covers descriptive metrics (mean, median, standard deviation, CPK) and process capability indices relevant to ISO 22514. Raw data exports to CSV, Excel, or XML formats preserve metadata (operator ID, timestamp, environmental conditions, calibration status) for regulatory submission. Audit trails log all parameter modifications, test executions, and report generations with immutable timestamps.
Applications
- Peel strength evaluation of pressure-sensitive adhesives, laminated packaging, and medical device tapes (GB/T 2792, ASTM D903, PSTC-107).
- Tensile property mapping of thermoplastics, thermosets, and biodegradable polymers (ISO 527, ASTM D638).
- Compression resilience testing of polyurethane foams and elastomeric gaskets (ISO 1856, ASTM D3574).
- Mechanical fatigue assessment of springs, rubber mounts, and vibration-damping components under controlled displacement or load cycling.
- Quality conformance verification for automotive interior trims, textile composites, and consumer electronics housings.
- Research-grade mechanical profiling in academic polymer science, biomaterials, and additive manufacturing labs.
FAQ
Does the YL-S70 support ASTM and ISO-compliant test methods out of the box?
Yes—the software includes preconfigured templates for ASTM D638, D790, D903, ISO 527, ISO 178, and GB/T 2792, with editable parameters to meet lab-specific SOPs.
Can the system be integrated into an existing LIMS or MES environment?
Via RS-232 serial interface and optional TCP/IP Ethernet module, raw data and summary reports can be exported to external databases using standardized CSV or XML schemas.
Is calibration documentation provided with shipment?
Each unit ships with a factory calibration certificate traceable to national metrology institutes, including uncertainty budgets and as-found/as-left data for force and displacement axes.
What maintenance intervals are recommended for sustained accuracy?
Annual verification of force transducer linearity and ball screw backlash is advised; routine cleaning of guideways and periodic lubrication of drive components are specified in the operator manual.
Are third-party夹具 (fixtures) compatible with the quick-connect interface?
The YL-S70 uses a standardized M6 threaded mounting pattern conforming to ISO 2041; most commercially available universal grips and environmental chambers integrate without modification.
