North Guang BWN-10KN 50 kV Electronic Universal Testing Machine

Overview

The North Guang BWN-10KN Electronic Universal Testing Machine is a precision-engineered static mechanical testing system designed for high-reproducibility tensile, compression, flexural, and peel testing of non-metallic materials—including thermoplastics, elastomers, composites, films, foams, adhesives, and rubber compounds. Operating on the principle of servo-controlled electromechanical actuation, the system applies controlled axial force via a high-rigidity load frame driven by a Panasonic AC servo motor and precision ground ball screw assembly. Force is measured using a calibrated U.S.-sourced load cell with dual-range linearity and integrated thermal compensation; displacement is captured via a high-resolution optical encoder with noise-immune LINE DRIVE interface. The machine conforms to ISO 7500-1 and ASTM E4 requirements for Class 0.5 verification, ensuring traceable metrological integrity across its full 10 kN capacity range.

Key Features

• Precision Force Control Architecture: Dual-mode control—constant load, constant displacement, and constant strain rate—with programmable ramp-hold profiles and multi-stage loading sequences compliant with ISO 6892-1 and ASTM D638 Annex A2.
• High-Fidelity Data Acquisition: 24-bit analog-to-digital conversion at 200 Hz sampling rate; real-time synchronization of force, displacement, and time stamps with microsecond-level timestamp resolution.
• Modular Environmental Integration: Designed for seamless coupling with external environmental chambers (−70 °C to +300 °C), enabling standardized creep, stress-relaxation, and low/high-temperature mechanical characterization per ISO 899-1 and ASTM D2990.
• Intelligent Safety & Protection: Hardware-based overload cutoff (±110% FS), overcurrent/overvoltage monitoring, thermal shutdown, dual-limit position sensing, and emergency stop interlock per IEC 60204-1.
• Multi-Standard Test Automation: Pre-configured test methods for GB/T, ISO, ASTM, DIN, JIS, and BS standards—including tensile (GB/T 1040.1, ISO 527-1), compression (GB/T 1041, ISO 604), flexure (GB/T 9341, ISO 178), tear (ISO 34-1, ASTM D624), and peel (ASTM D903, GB/T 7122).
• Advanced Curve Analysis Engine: Region-specific zoom, overlay comparison of up to 16 curves with color-coded legends, arbitrary point interrogation, tangent modulus calculation, yield point detection (0.2% offset, ISO 6892-1), and automatic peak/valley extraction.

Sample Compatibility & Compliance

The BWN-10KN accommodates standardized specimen geometries per international material testing protocols: dumbbell-shaped (Type I–V per ISO 527), rectangular strips (10–25 mm wide), cylindrical rods (4–12 mm diameter), angular bend specimens (90° or 180°), and custom die-cut configurations. Fixture options include pneumatic wedge grips, hydraulic self-tightening clamps, three-point bending fixtures, peel test jigs, and specialized rubber tear fixtures (trouser, crescent, and right-angle). All mechanical tests comply with Good Laboratory Practice (GLP) documentation requirements, including audit-trail-enabled data logging, electronic signature support (per FDA 21 CFR Part 11), and calibration certificate traceability to NIM (China National Institute of Metrology) or NIST-equivalent standards.

Software & Data Management

UTM107 v5.x software—running natively on Windows XP through Windows 11—provides a fully modular, standards-driven interface with multilingual support (English, Simplified/Traditional Chinese). Its architecture supports dynamic unit conversion (N, kN, lbf, kgf, MPa, psi), auto-scaling graphical rendering, and customizable report generation via embedded Excel export. The software implements full test method templating: users select from >120 preloaded standards (e.g., ASTM D638, ISO 37, GB/T 528), define specimen geometry and conditioning parameters, and execute automated calculations for tensile strength, elongation at break, Young’s modulus, yield stress, tear resistance, peel adhesion, and flexural modulus. Raw data (.csv, .txt) and processed results (.xlsx, .pdf) are stored with metadata tagging (operator ID, timestamp, instrument ID, calibration due date) and support hierarchical backup to network drives or NAS systems.

• Academic research in soft matter mechanics requiring high-resolution force-displacement mapping

FAQ

What is the maximum test speed and minimum crosshead resolution?
The crosshead speed is adjustable from 0.001 mm/min to 500 mm/min, with displacement resolution of 0.001 mm achieved via a 2500 P/R optical encoder with quadrature interpolation.
Does the system support GLP-compliant data archiving?
Yes—UTM107 software provides full audit trail logging, user access controls, electronic signatures, and immutable raw data storage aligned with FDA 21 CFR Part 11 and ISO/IEC 17025 requirements.
Can environmental chambers be integrated without hardware modification?
Yes—the BWN-10KN features standardized chamber mounting interfaces and RS232/RS485 communication ports compatible with leading environmental chamber vendors (ESPEC, Weiss, Angelantoni) for synchronized temperature-humidity-force profiling.
Is calibration traceable to national metrology institutes?
All factory calibrations are traceable to NIM (China) with optional NIST-traceable certificates available upon request; annual recalibration intervals follow ISO/IEC 17025 guidelines.
What third-party standards does the software natively support?
Over 120 preconfigured test methods covering GB/T, ISO, ASTM, DIN, JIS, BS, CNS, and GOST standards—including tensile, compression, flexure, tear, peel, and creep modules.
