Jiubin JB-118 Universal Material Testing Machine

Overview

The Jiubin JB-118 Universal Material Testing Machine is an electromechanically integrated static mechanical testing system engineered for precision tensile, compression, flexural, peel, tear, and shear characterization of engineering materials. It operates on the fundamental principle of controlled displacement-driven loading, where a servo-controlled actuator applies calibrated force via a high-rigidity transmission train while synchronized load and displacement feedback—captured by a traceable, NIST-compatible load cell and optical encoder—is acquired at ≥1 kHz sampling rate. Designed to meet foundational requirements of ISO 6892-1 (metallic tensile testing), ASTM E4 (force verification), and ASTM E83 (extensometer verification), the JB-118 delivers repeatable, audit-ready mechanical property data across R&D labs, QC departments, and contract testing facilities handling metals, polymers, elastomers, composites, textiles, leather, and electrical insulation components.

Key Features

• Modular dual-control architecture: Independent microcomputer controller for real-time parameter monitoring and PC-based software for advanced test sequencing, curve analysis, and report generation.
• High-fidelity force measurement: USA-sourced strain-gauge load cell with ±0.5% full-scale accuracy, thermally compensated and factory-calibrated per ISO 376 Class 0.5 standards.
• Precision motion control: Dual-drive configuration—Japanese servo motor for low-speed high-torque stability (0.001 mm/min) and Taiwanese AC motor for rapid positioning (up to 500 mm/min)—enabling both quasi-static and dynamic ramp tests.
• Backlash-free mechanical train: Hybrid transmission combining Taiwan-manufactured precision ball screws (C5 grade) and Korea-sourced preloaded lead screws, ensuring <0.01 mm axial play and long-term dimensional repeatability.
• Comprehensive safety redundancy: Dual-limit mechanical stops, hardware-interrupt emergency stop circuitry, and software-enforced operational bounds prevent over-travel or overload damage.
• Configurable extensometry support: Optional two-point digital extensometer (not included) compatible with ASTM E83 Class B compliance for strain measurement in tensile yield and elongation-at-break determination.

Sample Compatibility & Compliance

The JB-118 accommodates specimens ranging from thin polymer films (≥0.05 mm thickness) to structural metal coupons (up to 50 mm width × 10 mm thickness). Standard wedge-action grips, pneumatic clamps, and custom fixtures—including vise-type, pin-loaded, and peel-adhesion fixtures—are available per ISO 20795-1, ASTM D638, ISO 527, and ISO 179 specifications. All mechanical components comply with CE Machinery Directive 2006/42/EC. Force calibration documentation supports traceability to national metrology institutes (NMI), and system-level validation reports align with GLP and internal QA protocols. While not inherently 21 CFR Part 11 compliant, the optional PC software package supports electronic signature, audit trail, and user-access controls when deployed on validated Windows OS environments.

Software & Data Management

The JB-118 integrates with proprietary Windows-based testing software supporting multi-step test programs (tensile-to-failure, cyclic loading, creep hold, stress relaxation). Raw data is logged at ≥1 kHz with timestamped metadata (operator ID, sample ID, environmental conditions if sensor-integrated). Export formats include CSV, Excel, PDF, and XML for LIMS integration. Curve overlay, modulus calculation (secant/tangent), yield point detection (0.2% offset), and statistical batch reporting (mean, SD, CV%) are embedded. Data integrity safeguards include automatic file versioning, write-protected archives, and configurable auto-backup to network drives. Software validation documentation (IQ/OQ templates) is provided upon request for regulated environments.

Applications

• Metallic material qualification per ASTM E8/E21: Yield strength, ultimate tensile strength, elongation, reduction of area.
• Plastic and rubber characterization per ISO 527/ISO 37: Tensile modulus, breaking strength, elongation at break, stress-strain hysteresis.
• Adhesive bond evaluation per ASTM D1876 (T-peel), ASTM D903 (peel strength), and ISO 8510-2.
• Textile and nonwoven testing per ISO 9073-3 (tensile strength), ISO 9073-4 (tear resistance).
• Wire and cable jacket integrity per UL 1581 §1060 (tensile elongation), IEC 60811-501.
• Medical device component validation (e.g., suture tensile strength per ISO 10555-1, catheter shaft stiffness).

FAQ

What is the maximum allowable specimen height for compression testing?
The effective vertical clearance between platens is 1000 mm; however, maximum usable height depends on required stroke and fixture stack-up—typically ≤850 mm for standard configurations.
Does the system support ASTM E23 for Charpy impact testing?
No—the JB-118 is a static universal tester and does not support pendulum impact methods. Impact testing requires dedicated Izod/Charpy systems.
Can the load cell be recalibrated in-house?
Yes—calibration can be performed using certified deadweight standards or reference load cells traceable to national standards; full calibration procedures and tolerance tables are included in the technical manual.
Is third-party ISO 17025 accreditation support available?
Jiubin provides factory-issued calibration certificates and uncertainty budgets; external accreditation must be arranged through an ILAC-recognized laboratory using the JB-118’s documented metrological specifications.
What operating system versions are supported by the PC software?
Windows 10 (64-bit) and Windows 11 (64-bit); legacy support for Windows 7 ends Q4 2025 per software maintenance policy.
