Overview
The Hengyi HY(JX)-50J Digital Readout Charpy/IZOD Impact Tester is a precision-engineered pendulum-type impact testing system designed for the quantitative determination of impact resistance and notch sensitivity in rigid non-metallic materials. Based on the fundamental principles of conservation of energy and angular momentum, the instrument measures the energy absorbed by a standardized specimen during fracture under a single, high-velocity pendulum impact—compliant with both Charpy and Izod configurations via adjustable specimen clamping geometry. This dual-mode capability enables laboratories to evaluate material toughness across diverse geometries and loading conditions, supporting quality assurance, R&D validation, and regulatory compliance in polymer science, composites engineering, and advanced ceramics development.
Key Features
- High-resolution digital readout system featuring a 7-inch color touch-screen interface with switchable English/Chinese language support
- Carbon-fiber pendulum arm engineered for enhanced rigidity and minimized torsional deflection, ensuring precise mass concentration at the pendulum center of gravity and eliminating parasitic vibrations during impact
- Imported Omron rotary encoder with angular resolution of 0.01°, delivering stable and repeatable position tracking throughout the swing arc
- Aerodynamically optimized impact hammer with precision-ground 30° chamfered edge (R = 2.0 ± 0.5 mm) and hardened steel bearing surfaces
- Low-friction, sealed stainless-steel ball bearings integrated into the pendulum pivot assembly to minimize mechanical hysteresis and energy loss
- Automatic post-test calculation of absorbed energy, with onboard storage for up to 12 test records and statistical averaging functionality
- Multi-unit output support: J/m, kJ/m², kg·cm/cm, ft·lb/in—enabling seamless alignment with regional reporting conventions
- Integrated thermal printer for immediate hard-copy documentation of test parameters and results
Sample Compatibility & Compliance
The HY(JX)-50J accommodates standardized specimens per ISO 179-1:2019 (Plastics — Determination of Charpy impact properties), ISO 180:2019 (Izod impact strength), GB/T 1043.1–2018, and GB/T 18743–2022 (for thermoplastic pipe sections). It supports specimen spans of 40 mm, 60 mm, 70 mm, and 95 mm, with support knife-edge radius of R = 1.0 mm and impact blade radius of R = 2.0 ± 0.5 mm. The system meets mechanical accuracy requirements defined in JB/T 8762–2019 (Pendulum Impact Testing Machines for Plastics) and conforms to essential metrological traceability standards for laboratory accreditation (ISO/IEC 17025). While not inherently 21 CFR Part 11 compliant, its data logging architecture supports integration with validated LIMS environments where audit trails and electronic signatures are required.
Software & Data Management
The embedded firmware implements deterministic real-time acquisition synchronized with pendulum angular displacement. All raw encoder counts, time-stamped impact events, and calculated energy values are stored locally in non-volatile memory with timestamp and operator ID fields (configurable). Export is supported via USB flash drive in CSV format for downstream analysis in MATLAB, Excel, or statistical process control (SPC) platforms. No proprietary software installation is required; however, optional PC-based analysis modules are available for trend charting, Weibull failure modeling, and batch report generation aligned with GLP/GMP documentation workflows.
Applications
- Quantitative assessment of brittle-to-ductile transition behavior in thermoplastics (e.g., ABS, PC, POM) and fiber-reinforced composites
- Quality control screening of injection-molded components for automotive and electronics housings
- Comparative evaluation of aging effects (UV, thermal, hydrolytic) on polymer impact performance
- Validation of material substitutions in medical device housing design per ISO 10993 biocompatibility frameworks
- Research-grade fracture mechanics studies involving pre-notched specimens under controlled temperature/humidity environments (when paired with environmental chamber)
- Teaching laboratories requiring reproducible, low-maintenance impact demonstrations aligned with ASTM D6110 and ISO curricula
FAQ
What standards does the HY(JX)-50J fully comply with?
It satisfies the mechanical and geometric requirements of ISO 179-1:2019, ISO 180:2019, GB/T 1043.1–2018, GB/T 18743–2022, and JB/T 8762–2019.
Can the tester be configured for both Charpy and Izod tests?
Yes—the base frame includes interchangeable anvil assemblies and specimen clamps to support both test configurations without hardware modification.
Is calibration certification included with shipment?
Each unit ships with a factory calibration certificate traceable to CNAS-accredited reference standards; third-party ISO 17025 calibration services are available upon request.
What is the typical repeatability (coefficient of variation) for repeated tests on homogeneous PMMA specimens?
Under controlled lab conditions (23°C ± 1°C, 50% RH), CV remains ≤ 2.1% for n ≥ 10 per ASTM D6110 Annex A1 protocols.
Does the system support external data acquisition via analog or digital I/O?
It features RS-232 and USB-C ports for host communication; analog voltage output (0–5 V) for real-time torque signal is available as an optional add-on module.
