Yuelian YL-S90 Digital Universal Testing Machine for Peel Strength and Mechanical Property Evaluation

Overview

The Yuelian YL-S90 is an electromechanical universal testing machine engineered for high-reproducibility mechanical property evaluation of thin-film, laminated, and flexible materials. It operates on a closed-loop stepper motor–driven actuation system coupled with a preloaded precision ball screw, delivering stable force generation and sub-micron displacement resolution across its full stroke range. Designed specifically for peel strength assessment per ASTM D3330 and GB/T 2792, the system also supports tensile, compressive, tear, shear, and loop tack testing in accordance with ISO 11339, ASTM D882, ASTM D638, and GB/T 1040 series standards. Its modular architecture enables seamless integration into quality control laboratories operating under GLP or GMP frameworks, where traceability, audit readiness, and repeatable test execution are mandatory.

Key Features

• High-efficiency mechanical transmission (>85% efficiency) minimizes thermal drift and ensures consistent load application over extended test durations.
• Programmable speed control from 0.1 to 500 mm/min with real-time feedback, supporting both quasi-static and dynamic peel rate protocols.
• Dual-range load cell configuration option allows calibration traceability across low-force (e.g., pressure-sensitive adhesive peel) and higher-force (e.g., composite laminate delamination) regimes without hardware changeover.
• Integrated quick-release grip interface accommodates standardized peel fixtures (90°, 180°, T-peel), tensile jaws, compression platens, and custom tooling—enabling rapid method switching.
• Onboard microprocessor controller permits standalone operation with simultaneous digital display of force (N, kgf, lbf) and displacement (mm), while USB/RS-232 connectivity enables full PC-based test sequencing and data acquisition.
• Automated safety logic includes overload cutoff, programmable upper/lower limit stops, specimen rupture detection, emergency stop, and auto-return-to-initial-position post-test—ensuring operator safety and equipment protection.

Sample Compatibility & Compliance

The YL-S90 is validated for testing specimens ranging from ultra-thin polymer films (≥12 µm) to multilayer packaging composites, nonwovens, coated papers, elastomeric tapes, and textile laminates. Its 110 mm test width and adjustable crosshead height support standard specimen geometries defined in ISO 8510-2 (peel adhesion), ASTM D6252 (loop tack), and GB/T 2792 (180° peel). All firmware and software modules comply with data integrity requirements aligned with FDA 21 CFR Part 11 principles—including electronic signature support, audit trail logging, and user-access-level management—facilitating regulatory submissions and internal QA audits.

Software & Data Management

The included Windows-compatible software provides ISO/IEC 17025-aligned test method templates, customizable pass/fail criteria, and automated calculation of key metrics: average peel force, peak force, energy-to-peel (area under curve), coefficient of variation (CV%), and statistical summaries (mean, SD, min/max). Raw data exports to CSV and Excel formats preserve full timestamped force-displacement time-series resolution. The software supports multi-user profiles with role-based permissions and maintains immutable records of all test parameter modifications, result annotations, and calibration events—meeting GLP documentation requirements for pharmaceutical, medical device, and food packaging validation studies.

Applications

• Peel strength verification of pressure-sensitive adhesives (PSA) on release liners and backing substrates.
• Quality assurance of flexible packaging seal integrity (heat-sealed, cold-sealed, or adhesive-bonded).
• Characterization of interlaminar adhesion in battery electrode coatings, photovoltaic backsheets, and aerospace prepregs.
• Tensile modulus and elongation-at-break measurement of elastomeric films per ASTM D412.
• Tear resistance evaluation of nonwoven medical gowns using trapezoidal or tongue tear methods (ASTM D5730).
• Loop tack and probe tack quantification for hot-melt and acrylic adhesives per ASTM D6195 and PSTC-15.

FAQ

Does the YL-S90 meet international regulatory requirements for lab instrument validation?
Yes—the system supports IQ/OQ documentation packages, includes factory calibration certificates traceable to NIM (China National Institute of Metrology), and implements software features compliant with FDA 21 CFR Part 11 and EU Annex 11 for electronic records and signatures.
Can the YL-S90 perform cyclic or dwell tests?
Yes—via PC software, users can define multi-step test profiles including hold periods at specified loads or displacements, enabling creep, stress relaxation, and fatigue simulation protocols.
Is third-party calibration service available?
Yes—Yuelian partners with ISO/IEC 17025-accredited calibration laboratories in APAC and EMEA regions; annual recalibration intervals are recommended per ISO 9001 and internal QA policies.
What is the warranty coverage and service response time?
The YL-S90 carries a 24-month parts-and-labor warranty; technical support is provided remotely within 4 business hours, with on-site service available under extended support contracts.
Are ASTM- or ISO-compliant test fixtures included?
Standard configurations include 90° and 180° peel fixtures conforming to ASTM D3330 Annex A2 and GB/T 2792; additional fixtures (T-peel, floating roller, loop tack probes) are available as optional accessories with documented dimensional compliance reports.
