Overview
The Yuelian YL-S70 Computer-Controlled Universal Tensile Testing Machine is an electromechanical materials testing system engineered for precision mechanical property characterization across research laboratories, quality control departments, and production environments. Based on the fundamental principles of uniaxial static loading under controlled displacement or force regulation, the YL-S70 employs a high-fidelity closed-loop servo control architecture to execute standardized mechanical tests—including tensile, compression, flexural (3-point and 4-point), shear, tear, peel, puncture, cyclic fatigue, and creep hold protocols—in strict compliance with internationally recognized test methodologies. Its modular mechanical design integrates a low-inertia AC servo motor, preloaded recirculating ball screw transmission, and high-resolution optical encoder feedback to ensure traceable kinematic fidelity and repeatable force application over extended operational lifecycles. The system supports full traceability workflows required in regulated industries through configurable audit trails, user access levels, and electronic signature support—facilitating alignment with GLP, ISO/IEC 17025, and FDA 21 CFR Part 11 documentation requirements when deployed with validated software configurations.
Key Features
- Precision dual-range load cell options from 10 N to 5 kN, enabling high-resolution measurement across both delicate thin-film substrates and robust structural composites
- Real-time 2000 Hz data acquisition rate ensures accurate capture of transient mechanical events such as yield onset, necking propagation, and brittle fracture initiation
- Force resolution of 1 part in 500,000 full scale and displacement accuracy of ±0.1% meet ASTM E4, ISO 7500-1, and JJG 475 calibration standards for Class 0.5 systems
- Modular quick-connect fixture interface allows tool-free replacement of grips, bend fixtures, peel jigs, and puncture probes—reducing changeover time by >70% compared to bolted-mount alternatives
- Integrated safety architecture includes hardware-enforced stroke limits, dual-channel emergency stop circuitry, and programmable overload cutoff thresholds—certified to IEC 61800-5-2 functional safety guidelines
- Industrial-grade ABS enclosure with electrostatically applied matte finish resists chemical exposure, abrasion, and UV degradation during long-term operation in shared lab spaces
Sample Compatibility & Compliance
The YL-S70 accommodates specimens ranging from micro-thin polymer films (<10 µm) to rigid metal coupons (up to 15 mm thickness) and assembled consumer goods (e.g., footwear soles, corrugated packaging, foam cushions). Its Ø140 mm test chamber and 450 mm vertical stroke enable evaluation of ASTM D882 (thin plastics), ISO 527 (tensile properties), ASTM D638 (rigid plastics), ISO 179 (impact-modified polymers), ASTM D3763 (high-speed puncture), ISO 1133 (melt flow index correlation), and TAPPI T813 (paperboard compression). All firmware and software modules are designed to support configurable test method templates aligned with ISO 14577 (instrumented indentation), ASTM D1876 (T-peel), and EN 13130-1 (food contact material migration simulation under mechanical stress). System validation documentation—including IQ/OQ protocols, uncertainty budgets, and metrological traceability statements—is available upon request for GMP-regulated environments.
Software & Data Management
The proprietary YL-TestSuite v4.2 software provides a deterministic real-time operating environment compliant with Windows 10/11 LTSB editions. It delivers synchronized multi-curve visualization with adjustable interpolation, dynamic zoom, and pixel-accurate cursor interrogation. Statistical post-processing includes CPK capability analysis for process stability assessment, coefficient-of-variation reporting for inter-lot consistency verification, and Weibull modulus estimation for failure probability modeling. Raw ASCII data exports (CSV/TXT) preserve all 2000-Hz timestamps and sensor channels for third-party analysis in MATLAB, Python (NumPy/Pandas), or JMP. Audit trail logs record operator ID, timestamp, parameter changes, and result modifications with immutable SHA-256 hashing—meeting ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) data integrity criteria. Optional 21 CFR Part 11 add-on enables electronic signatures, role-based permissions, and electronic record retention policies.

FAQ
Is the YL-S70 compliant with ISO/IEC 17025 accreditation requirements for testing laboratories?
Yes—the base system meets mechanical metrology requirements of ISO/IEC 17025:2017 Clause 6.4 (Equipment) and Clause 7.7 (Ensuring validity of results) when operated with certified reference standards and documented calibration intervals. Full accreditation support packages include calibration certificates traceable to NIM (China) or NIST (USA), uncertainty budgets, and method validation reports.
Can the YL-S70 perform cyclic fatigue testing with variable amplitude waveforms?
Yes—via the Advanced Cycling Module (optional), users can define asymmetric sine, triangle, trapezoidal, or custom waveform profiles with programmable R-ratios, dwell periods, and stepwise amplitude modulation—enabling ASTM D3479 (tension-tension fatigue) and ISO 1099 (metal fatigue) conformance.
Does the system support automated report generation with company branding and regulatory headers?
Yes—template-driven reporting allows insertion of institutional logos, QA-approved disclaimers, regulatory statement blocks (e.g., “This report complies with ISO 17025:2017”), and digital signature fields—all exportable as PDF/A-1b for long-term archival compliance.
