Overview
The Yuelian YL-S70 Servo-Controlled Tensile Testing Machine is a precision electromechanical universal testing system engineered for high-reproducibility mechanical characterization of materials and components under uniaxial loading conditions. Based on closed-loop servo motor control and precision ground ball-screw transmission, the YL-S70 implements standardized quasi-static mechanical testing in accordance with ISO 6892-1, ASTM E8/E21, GB/T 228.1, and other internationally recognized tensile testing protocols. Its modular architecture supports a broad spectrum of test modes—including tension, compression, bending (3-point and 4-point), shear, tear, peel, puncture, and cyclic loading—making it suitable for R&D laboratories, QC departments, and contract testing facilities across polymer, automotive, packaging, medical device, textile, and electronics industries.
Key Features
- High-fidelity force measurement with 1/500,000 full-scale resolution and ±0.1% accuracy, traceable to national metrological standards;
- Real-time displacement sensing with sub-micron resolution (1/500,000 mm) and ±0.1% linearity across the full 450 mm effective stroke;
- Wide dynamic speed range (0.001–500 mm/min), programmable in 0.001 mm/min increments, enabling both slow creep and rapid failure analysis;
- Modular quick-change fixture interface compatible with standard ISO/ASTM-compliant grips (tensile, compression platens, bend fixtures, peel jigs, puncture probes);
- Dual-range load cell configuration option for enhanced low-load sensitivity and high-load robustness within a single frame;
- Integrated safety architecture: hardware-enforced overload cutoff, dual-channel emergency stop circuitry, mechanical end-limit switches, and software-configurable upper/lower position limits;
- Aluminum extrusion protective shrouding with sandblasted anodized finish; ABS structural housing with electrostatic powder coating for long-term corrosion resistance and cleanroom compatibility.
Sample Compatibility & Compliance
The YL-S70 accommodates specimens ranging from thin films (<0.01 mm) and elastomeric foams to rigid composites and metallic wires, provided dimensional constraints (Ø140 mm test zone diameter, 450 mm vertical clearance) are observed. Standard test methods supported include ISO 527 (plastics), ISO 179 (impact-modified polymers), ASTM D882 (thin plastic sheeting), ASTM D638 (tensile properties of plastics), ASTM D3039 (composite tensile), GB/T 7742 (fabric tear), and GB/T 2792 (peel adhesion). All firmware and software modules comply with GLP documentation requirements, including audit-trail-enabled user authentication, electronic signature support, and timestamped raw data logging—fully aligned with FDA 21 CFR Part 11 readiness when deployed with validated configurations.
Software & Data Management
The proprietary Windows-based control and analysis suite delivers full IEC 62304-compliant operation with real-time multi-curve visualization (force-displacement, force-time, displacement-time, stress-strain). It supports up to seven user-defined test intervals per run, 40 manual data points, and 120 auto-sampled points per curve. Statistical post-processing includes mean, median, standard deviation, coefficient of variation (CV), CPK, and outlier-filtered averaging (high/low exclusion). Historical datasets can be overlaid for comparative trend analysis. Custom test method templates may be defined using nested step logic—e.g., ramp-to-load → hold → ramp-to-strain → unload → retest at reduced rate—with automatic return-to-start, fracture detection, and zero-reset functions. Raw ASCII and CSV export formats ensure seamless integration with LIMS, MES, and statistical process control (SPC) platforms.
Applications
- Quality assurance of adhesive tapes, labels, and laminated packaging films (peel strength, tack, holding power);
- Mechanical validation of biomedical sutures, catheter tubing, and hydrogel wound dressings;
- Compression testing of polyurethane foams, rubber gaskets, and battery electrode stacks;
- Cyclic fatigue evaluation of springs, elastomeric mounts, and micro-electromechanical systems (MEMS) interconnects;
- Three-point flexural testing of PCB substrates, ceramic tiles, and fiber-reinforced composites;
- Puncture resistance assessment of footwear soles, protective gloves, and medical drapes;
- Creep and stress-relaxation profiling of thermoplastics and viscoelastic biomaterials under controlled environmental chambers (when integrated).
FAQ
Is the YL-S70 compliant with ISO/IEC 17025 calibration requirements?
Yes—the system is designed to support accredited calibration per ISO/IEC 17025:2017. Load cells and displacement encoders are supplied with factory calibration certificates traceable to CNAS-accredited reference standards. Optional on-site verification and uncertainty budgeting services are available through authorized service partners.
Can the YL-S70 perform ASTM D3479 fatigue testing?
Yes—its programmable multi-step control engine enables fully automated tension-tension or tension-compression cycling per ASTM D3479, with cycle counting, amplitude modulation, and failure detection logic embedded in the test sequence editor.
What operating systems are supported by the control software?
The current release supports Windows 10 and Windows 11 (64-bit) with .NET Framework 4.8 and Microsoft Visual C++ Redistributables installed. Legacy Windows 7 support is maintained for existing deployments under extended maintenance agreements.
Is remote monitoring or networked data export possible?
Yes—the system includes TCP/IP and RS-232 interfaces. Real-time force/displacement streaming, alarm notifications, and scheduled report exports (PDF/CSV) can be configured via LAN/WAN. Integration with OPC UA or MQTT brokers is supported through optional middleware modules.
Does the YL-S70 meet CE or UKCA marking requirements for export to Europe/UK?
The base configuration complies with the essential health and safety requirements of the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. CE marking documentation—including risk assessment, technical file summary, and EU Declaration of Conformity—is provided upon request for customs clearance and regulatory submission.
