Overview
The Yuelian YL-S70 Electronic Tensile Testing Machine is a high-precision, servo-controlled universal testing system engineered for static mechanical property evaluation of materials and components across R&D laboratories, quality control departments, and contract testing facilities. It operates on the fundamental principle of controlled uniaxial force application—measuring load response under precisely regulated displacement or strain rate—to determine tensile strength, compressive yield, flexural modulus, tear resistance, peel adhesion, puncture force, and cyclic deformation behavior. Designed in accordance with ISO 7500-1 (static calibration of force-measuring systems) and ASTM E4 (load verification of testing machines), the YL-S70 delivers traceable, repeatable results suitable for internal method validation, supplier qualification, and regulatory documentation workflows.
Key Features
- Servo motor-driven precision ball screw transmission system ensures smooth, low-noise motion control with minimal backlash and thermal drift.
- Robust aluminum extrusion guard housing with sandblasted & anodized silver finish; ABS polymer enclosure with electrostatic powder coating for chemical resistance and long-term structural integrity.
- Micro-adjustment limit switches at upper and lower travel extremes enable precise positioning during fixture alignment and specimen setup.
- Quick-release modular fixture interface supports rapid interchange of standardized grips—including pneumatic, wedge, vise, peel, and puncture configurations—without tools.
- Comprehensive hardware safety suite: over-travel limit protection, overload cut-off, emergency stop button, and automatic fracture detection with programmable post-failure return-to-start.
- High-resolution dual-channel acquisition: 1/500,000 full-scale force resolution and 1/500,000 mm displacement resolution, enabling sub-micron positional fidelity and sub-newton force sensitivity.
Sample Compatibility & Compliance
The YL-S70 accommodates a broad spectrum of sample geometries and material classes—including polymers, elastomers, composites, textiles, foams, adhesives, packaging films, medical tubing, footwear soles, corrugated cardboard, and metallic foils—via interchangeable fixtures compliant with ASTM D882 (thin plastic film), ASTM D638 (tensile properties of plastics), ISO 527 (plastics tensile testing), ISO 179 (impact bending), and TAPPI T813 (paperboard compression). All force transducers are factory-calibrated per ISO 376 and include NIST-traceable certificates. The system architecture supports audit-ready operation under GLP and GMP environments, with optional 21 CFR Part 11-compliant software modules providing electronic signatures, audit trails, and user access controls.
Software & Data Management
Built-in Windows-native test software provides full closed-loop control with 120 auto-capture points, 40 manual data markers, and up to seven user-defined analysis intervals per test. Real-time plotting supports simultaneous display of force–displacement, force–time, displacement–time, and stress–strain curves—with dynamic zoom, pan, crosshair cursor, and point extraction functions. Statistical reporting includes mean, standard deviation, coefficient of variation (CV), CPK, min/max, median, and trimmed mean (excluding top/bottom outliers). Historical datasets can be overlaid for comparative trend analysis across batches, suppliers, or timepoints. Export formats include CSV, XLSX, PDF, and XML for LIMS integration. USB 2.0 and RS-232 interfaces ensure seamless connectivity with external PCs, PLCs, or industrial networks.

FAQ
What standards does the YL-S70 comply with for force calibration?
The load cell and measurement chain meet ISO 7500-1 Class 0.5 requirements, with factory calibration traceable to national metrology institutes via NIST-certified reference standards.
Can the system perform multi-step programmed tests with conditional logic?
Yes—users define nested sequences including speed changes, dwell periods, load thresholds, displacement limits, and automatic transitions between tension/compression phases.
Is bidirectional force sensing supported?
Yes—the integrated load cell supports both tensile and compressive loading without hardware reconfiguration, with polarity switching enabled in software.
Does the software support statistical process control (SPC) reporting?
Yes—it calculates CPK, PPK, control charts, histogram distributions, and capability indices directly from raw test data, exportable for SPC software integration.
What accessories are required for ASTM D882 film testing?
A pair of pneumatic film grips with adjustable clamping pressure and a calibrated extensometer (optional) are recommended for accurate strain measurement in thin-film applications.
