JuBin JB-117A Universal Testing Machine for Plywood and Engineered Wood Panels

Overview

The JuBin JB-117A Universal Testing Machine is an electromechanical static testing system engineered for precision mechanical characterization of plywood, particleboard, fiberboard, MDF, OSB, and other engineered wood panels. It operates on the principle of controlled uniaxial force application—measuring load versus displacement in tension, compression, bending (three- and four-point), shear, and fastener withdrawal modes. Designed to meet the stringent repeatability and traceability requirements of quality control laboratories in wood-based panel manufacturing, third-party certification bodies, and national building materials testing institutes, the JB-117A delivers high reproducibility across standardized test protocols defined by ISO, ASTM, EN, and GB standards. Its rigid frame architecture—reinforced with aluminum alloy enclosure and precision-machined load train components—minimizes deflection under load and ensures long-term calibration stability.

Key Features

• 10 kN single-range load cell with ±1% accuracy over 0.2–10 kN range, calibrated per ISO 7500-1 Class 1 requirements
• High-resolution displacement measurement via optical encoder (0.01 mm resolution), synchronized with load acquisition at ≥100 Hz sampling rate
• Wide-speed servo-controlled crosshead drive (0.01–500 mm/min), enabling both quasi-static bending tests and rapid failure characterization
• Dual-test-space configuration: 600 mm tensile clearance and 700 mm compression height, accommodating full-size structural specimens up to 1200 mm in length
• Modular fixture interface compatible with standardized grips and jigs—including three-point bending fixtures for static bending strength (MOR), roller supports for internal bond (IB) testing, wedge-splitting assemblies for glue-line shear, and threaded inserts for screw withdrawal resistance
• Integrated safety interlocks, emergency stop circuitry, and overload protection compliant with IEC 61800-5-2 for industrial environments

Sample Compatibility & Compliance

The JB-117A supports specimen geometries conforming to EN 310 (bending), EN 319 (tensile strength perpendicular to surface), EN 322 (moisture content correlation), ISO 16978 (surface bonding), and ASTM D1037 (wood-based panels). It accommodates specimens up to 360 mm wide and 50 mm thick—sufficient for full-thickness commercial plywood (e.g., 18 mm, 25 mm) and structural OSB. All test routines align with GLP-compliant documentation workflows; force and displacement data are timestamped and logged with audit-trail metadata. The system satisfies essential requirements for accreditation under ISO/IEC 17025:2017 for mechanical testing laboratories, including documented uncertainty budgets, periodic verification against certified reference standards, and traceable calibration certificates issued by CNAS-accredited providers.

Software & Data Management

The Windows-compatible control software provides real-time graphing of stress–strain, load–deflection, and time-series curves, with automatic identification of key parameters: modulus of rupture (MOR), modulus of elasticity (MOE), internal bond strength (IB), surface bonding strength, and screw withdrawal force. Data export is supported in CSV, Excel (.xlsx), and PDF report formats—with customizable templates aligned to GB/T 17657 Annex A reporting structures. Software features include multi-user role-based access control, electronic signature capability, and optional 21 CFR Part 11 compliance modules (audit trail logging, electronic records retention, and user authentication). Raw data files retain native acquisition resolution and are stored with embedded instrument ID, operator ID, environmental conditions, and calibration validity dates.

Applications

• Static bending tests per EN 310 and GB/T 1936.2 to determine MOR and MOE of softwood/hardwood plywood and laminated veneer lumber (LVL)
• Internal bond strength evaluation (EN 319, GB/T 17657) using tensile separation of core layers under controlled displacement rate
• Surface bonding strength assessment (EN 323, ISO 16978) via pull-off testing with bonded dolly fixtures
• Glue-line shear resistance quantification (ASTM D1037, GB/T 1937) using lap-shear or block-shear configurations
• Screw and nail withdrawal resistance measurement (EN 320, GB/T 1941) for evaluating fastener anchorage in load-bearing assemblies
• Compression parallel-to-grain testing of particleboard cores per EN 312 and GB/T 5849

FAQ

What international standards does the JB-117A support out-of-the-box?

The system includes pre-configured test methods for EN 310, EN 319, EN 322, ASTM D1037, ISO 16978, and all relevant Chinese GB/T standards cited in GB/T 17657–2022.
Can the machine be upgraded for dynamic fatigue testing?

No—the JB-117A is a static-only electromechanical tester. For cyclic loading applications (e.g., fatigue, creep), JuBin offers the JB-FAT series with electrodynamic actuation and closed-loop waveform control.
Is calibration traceability provided with delivery?

Yes—each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China) and includes documented uncertainty values per ISO/IEC 17025 requirements.
What maintenance intervals are recommended?

Lubrication of lead screws and inspection of belt tension are required every 500 operational hours; annual recalibration and verification of load cell linearity and displacement encoder accuracy are advised.
Does the software support networked laboratory data integration?

Yes—via optional LIMS API module supporting HL7 and ASTM E1384 message protocols for bidirectional data exchange with enterprise quality management systems.
