Yuelian YL-S90 Electronic Tensile Testing Machine for Peel Strength Testing of Flexible Composite Materials (Compliant with GB/T 8808–1988)

Overview

The Yuelian YL-S90 Electronic Tensile Testing Machine is a precision-engineered instrument designed specifically for quantitative mechanical evaluation of flexible laminated and composite materials—particularly peel strength testing in accordance with GB/T 8808–1988. Built upon a robust electromechanical architecture, the system employs a high-efficiency stepper motor coupled with a preloaded precision ball screw transmission mechanism (mechanical efficiency >85%), minimizing thermal drift and mechanical hysteresis during dynamic loading. The machine operates on the principle of controlled uniaxial force application under programmable displacement rate, enabling standardized measurement of interfacial adhesion performance across bonded substrates—including plastic films, aluminum foils, paper laminates, coated textiles, and rubber-to-film composites. Its modular design supports both standalone operation via embedded firmware logic and full integration into laboratory data management ecosystems through USB and RS-232 interfaces.

Key Features

• High-resolution force transduction with 1/500,000 full-scale resolution and certified accuracy of ±0.30% FS per ISO 7500-1 Class 1 requirements.
• Programmable crosshead speed ranging from 0.1 to 500 mm/min, adjustable in real time without interrupting test execution.
• Dual-mode control architecture: local single-button initiation for rapid qualification tests; full PC-based scripting for multi-step protocols including hold-at-load, ramp-hold-ramp, and cyclic peel sequences.
• Integrated auto-return function triggered upon test completion or specimen failure—reducing operator intervention and improving throughput consistency.
• Quick-release universal joint interface compatible with ASTM-standard peel fixtures (e.g., 90° and 180° peel clamps), T-peel grips, loop tack holders, and shear test platens.
• Real-time dual-channel display of force (N, kgf, lbf, MPa) and displacement (mm, µm) with automatic unit conversion and zero-point calibration verification.
• Hardware-level overload protection, emergency stop circuitry, and software-configurable upper/lower limit triggers ensure operational safety and test repeatability.

Sample Compatibility & Compliance

The YL-S90 accommodates specimens up to 110 mm wide and 500 mm travel length, supporting standard sample geometries defined in GB/T 8808–1988 (peel testing of soft composite packaging films), GB/T 2792 (adhesive tape peel resistance), and ASTM D3330 (pressure-sensitive tape peel adhesion). It meets metrological traceability requirements for QC laboratories operating under ISO/IEC 17025 accreditation frameworks. All firmware and software modules comply with basic data integrity principles aligned with FDA 21 CFR Part 11 Annex A expectations—including electronic signature support, audit trail logging, and user-access level configuration. Mechanical validation reports include certificate of conformity to GB/T 16491 for universal testing machines.

Software & Data Management

The included Windows-compatible software provides compliant data acquisition, visualization, and reporting functionality. Each test session generates timestamped raw data files (.csv and proprietary .yld format), preserving force-displacement curves at ≥100 Hz sampling rate. Statistical analysis tools calculate mean peel force, standard deviation, coefficient of variation, and pass/fail status against user-defined specification limits. Reports are exportable in PDF, Excel, and printer-ready formats—with configurable headers, logo insertion, and GLP-compliant metadata (operator ID, instrument ID, calibration due date, environmental conditions). Audit trail records capture all parameter modifications, test starts/stops, and result exports—supporting internal quality audits and regulatory inspections.

Applications

• Peel strength characterization of food packaging laminates (PET/AL/PE, BOPP/CPP, etc.) per GB/T 8808.
• Quality control of pressure-sensitive adhesive tapes per GB/T 2792 and ASTM D3330.
• Tensile property mapping of nonwovens, technical textiles, and elastomeric films under ISO 527 and GB/T 1040.
• Interlaminar shear testing of multilayer flexible electronics substrates.
• Initial tack and loop tack evaluation of hot-melt adhesives per GB/T 2191 and QB/T 2171.
• Compression behavior of foam gaskets and sealants per GB/T 14344.

FAQ

Does the YL-S90 support dual-capacity load cell configurations?
Yes—the YL-S90 platform accepts optional dual-range load cells (e.g., 100 N / 1 kN), enabling high-resolution low-force measurements without sacrificing upper-range capacity.
Is calibration documentation provided with shipment?
Each unit ships with a factory calibration certificate traceable to CNAS-accredited reference standards, valid for 12 months under normal usage conditions.
Can the system perform constant-rate-of-travel (CRT) and constant-rate-of-load (CRL) tests?
The firmware supports CRT mode natively; CRL control requires optional closed-loop feedback firmware upgrade and external load-cell-triggered velocity modulation.
What operating systems are supported by the control software?
The current release supports Windows 10 and Windows 11 (64-bit); legacy Windows 7 compatibility is maintained via LTS maintenance branch.
Are third-party夹具 (fixtures) compatible with the quick-connect interface?
Yes—any fixture conforming to ISO 26203-2 mechanical interface dimensions and torque specifications (M6 × 1.0 thread, 12 N·m max tightening) may be integrated.
