Overview
The YL-1125 Yuelian Universal Testing Machine is a high-precision electromechanical system engineered for standardized compression strength evaluation of fiberboard and other rigid or semi-rigid sheet materials used in packaging, construction, furniture, and transportation industries. It operates on the principle of controlled uniaxial loading—applying compressive force between parallel platens at programmable rates—while continuously measuring load and displacement to determine critical mechanical properties including ultimate compressive strength, modulus of elasticity in compression, yield stress (where applicable), and deformation behavior under sustained load. Designed in accordance with international metrological requirements for static force measurement systems (ISO 7500-1 Class 1), the machine delivers traceable, repeatable results suitable for QC laboratories, incoming material inspection, R&D validation, and regulatory documentation.
Key Features
- Modular dual-capacity load cell configuration supports seamless switching between high-sensitivity (e.g., 10 N–5 kN) and high-force (up to 50 kN) testing regimes without hardware recalibration.
- Precision ball screw actuation driven by a 750 W servo motor ensures smooth, low-noise motion control with sub-micron positioning repeatability and minimal thermal drift during extended test cycles.
- Full PC-based operation via USB interface enables real-time data acquisition at up to 1 kHz sampling rate, synchronized with video capture (optional) for deformation analysis.
- Integrated safety architecture includes overload cutoff, emergency stop circuitry, specimen failure auto-stop, and user-defined upper/lower displacement limits—all compliant with EN ISO 13850 functional safety requirements.
- Robust structural frame constructed from reinforced steel with 420 mm throat depth and 1200 mm vertical travel accommodates standard fiberboard specimens (e.g., ISO 16978, ASTM D6341) and custom-sized panels up to 400 mm × 400 mm.
Sample Compatibility & Compliance
The YL-1125 is validated for testing solid wood-based panels—including medium-density fiberboard (MDF), particleboard, oriented strand board (OSB), and high-density fiberboard—as well as composites, corrugated board, gypsum board, and polymer-laminated substrates. Specimen thickness range spans 3 mm to 60 mm; flatness tolerance ≤ 0.2 mm/m per ISO 20412. All mechanical calibrations are traceable to national standards (CNAS-accredited reference labs), and system verification follows ISO 7500-1 Annex C procedures. The instrument meets essential requirements of the EU Machinery Directive 2006/42/EC and supports audit-ready documentation for GLP, ISO/IEC 17025, and IATF 16949 environments.
Software & Data Management
The proprietary Windows-compatible software provides ISO/IEC 17025-compliant test sequence scripting, multi-curve overlay, statistical reporting (mean, SD, CV%), and export to CSV, PDF, or MS Access databases. It implements role-based user access control, electronic signature support, and full audit trail functionality aligned with FDA 21 CFR Part 11 requirements. Raw data files include timestamped metadata (operator ID, calibration certificate ID, environmental conditions), and all calculations—such as compressive strength (MPa), strain at peak load (%), and secant modulus—are performed using algorithms certified against NIST SP 800-111 guidelines. Software updates are delivered via secure HTTPS channel with SHA-256 integrity verification.
Applications
- Determination of compressive strength and stiffness of fiberboard per ISO 16978 and ASTM D6341 for packaging performance qualification.
- Validation of edge crush test (ECT) correlation for corrugated fiberboard assemblies under controlled humidity conditions.
- Interlaminar shear strength assessment of laminated fiberboard structures using modified ASTM D1037 protocols.
- Long-term creep behavior characterization under constant load (ISO 22313) for building material certification.
- Comparative evaluation of recycled-content fiberboard formulations in R&D settings, including moisture-conditioned specimens per ISO 22313 Clause 7.2.
FAQ
What standards does the YL-1125 comply with for fiberboard compression testing?
It supports ISO 16978, ASTM D6341, EN 312, and GB/T 17657 — all implemented through preconfigured test templates with automatic parameter validation.

Yes — the software supports multi-step load-control and displacement-control profiles, including ramp-hold-relax sequences per ISO 13314 for fatigue assessment.
Is third-party calibration certification included?
Factory calibration is provided with a traceable certificate (CNAS-recognized reference standards); optional annual recalibration services with ISO/IEC 17025 accreditation are available.
Does the machine support ASTM D1037 for wood-based panels?
Fully supported — including specimen conditioning, platen alignment verification, and reporting of modulus of rupture (MOR) and modulus of elasticity (MOE) in compression.
What maintenance intervals are recommended?
Lubrication of ball screw and guide rails every 500 operational hours; annual verification of load cell linearity and displacement encoder accuracy per ISO 7500-1.
