Beiguang Jingyi BW-N Electronic Universal Testing Machine for Peel and Tensile Testing

Overview

The Beiguang Jingyi BW-N Electronic Universal Testing Machine is an electromechanically driven static mechanical testing system engineered for high-reproducibility peel, tensile, compression, flexure, and shear evaluations of materials and bonded assemblies. It operates on the principle of controlled displacement or load-controlled actuation via a precision servo-motor-driven crosshead, coupled with real-time force and displacement feedback from calibrated load cells and linear encoders. Designed to meet fundamental requirements of ISO 6892-1 (metallic materials — tensile testing), ASTM D903 (peel resistance of adhesive bonds), ASTM D3330 (peel adhesion of pressure-sensitive tapes), and GB/T 2792 (Chinese national standard for peel strength), the BW-N supports standardized mechanical property characterization in QC laboratories, R&D centers, and production environments where traceable, repeatable test data are essential for material qualification and process validation.

Key Features

• Automatic test termination upon specimen failure — crosshead halts or returns to initial position based on user-defined criteria (e.g., load drop >15%, displacement threshold, or time-based trigger)
• Intelligent auto-ranging force measurement — dynamically selects optimal load cell range to maintain resolution and accuracy across multi-kN test spans
• Programmable test sequence architecture — users define multi-step protocols including pre-load dwell, ramp-to-load, constant-rate extension, stress relaxation, and cyclic loading
• Real-time dual-channel display — synchronized visualization of force vs. displacement, stress vs. strain, or custom derivative curves (e.g., modulus, energy absorption) during active testing
• Dual-stage safety protection — hardware-based mechanical limit switches complement software-enforced travel and overload thresholds (trip point: 103–105% of selected full-scale capacity)
• Modular fixture interface — standardized T-slot base and quick-mount adapters accommodate ASTM/ISO-compliant peel fixtures (90°, 180°), tensile grips (pneumatic, wedge, vise), compression platens, and bend supports
• Integrated environmental tolerance — stable operation within ambient temperatures of 10–35 °C and relative humidity ≤80%, with vibration-isolated mounting recommended for sub-0.1% repeatability

Sample Compatibility & Compliance

The BW-N accommodates specimens ranging from thin polymer films (<0.05 mm thick) to structural composites and metallic coupons up to 300 mm wide. Standard configurations support ISO 2411 (rubber and plastics — determination of peel resistance), ASTM D1876 (T-peel test), and IPC-TM-650 2.4.9 (adhesive bond strength for printed circuit boards). All firmware and control logic comply with GLP documentation standards; audit trails, electronic signatures, and user-access levels can be configured to align with FDA 21 CFR Part 11 requirements when paired with validated software deployment. Calibration certificates conform to ISO/IEC 17025 procedures and include as-found/as-left data traceable to NIM (National Institute of Metrology, China).

Software & Data Management

The included Windows-native testing software provides a bilingual (English/Chinese) GUI with role-based access control, method library management, and customizable report templates exportable in PDF, Excel, or XML formats. Raw data files (.tdf) store timestamped force, displacement, and calculated parameters at ≥100 Hz sampling rate. Software features include curve replay with dynamic point interrogation, batch analysis for identical specimen sets, automatic calculation of peel strength (N/mm), tensile strength (MPa), elongation at break (%), Young’s modulus (MPa), and area under curve (J/m²). Data integrity safeguards include write-once archive mode, checksum validation, and optional network backup to NAS or LIMS endpoints.

Applications

Typical use cases include quantitative evaluation of adhesive bond integrity in flexible packaging laminates, automotive interior trim bonding, medical device pouch seals, and aerospace composite layup tack. Additional applications span quality control of wire insulation tensile strength, rubber elasticity profiling, textile seam strength verification, and pharmaceutical blister foil peel performance per USP . The system serves as a foundational platform for ASTM F88/F903 barrier seal testing, ISO 11607-2 packaging validation, and internal specification development for supplier qualification programs.

FAQ

What standards does the BW-N support out-of-the-box?
Pre-configured test methods cover ASTM D903, D1876, D3330, ISO 6892-1, ISO 2411, and GB/T 2792. Custom method creation allows alignment with proprietary or industry-specific protocols.

Is the system compatible with third-party data acquisition systems?
Yes — analog outputs (±10 V) for force and displacement signals, plus RS-232 and Ethernet interfaces, enable integration with SCADA, MES, or custom LabVIEW environments.

How is calibration maintained over time?
Onboard self-diagnostics verify sensor linearity and zero drift prior to each test session. Annual recalibration using certified deadweight standards or accredited external service is recommended per ISO/IEC 17025.

Can the machine perform cyclic fatigue testing?
Standard firmware supports up to 999,999 cycles with programmable amplitude, frequency, and mean load — suitable for low-cycle fatigue assessment of elastomeric adhesives and thermoplastic welds.

What is included in the standard delivery package?
A full set includes the main frame, one pair of universal wedge grips, one 90° peel fixture, software license, USB calibration key, printed English/Chinese manuals, and 12-month parts-and-labor warranty. PC and printer are optional accessories.
