Overview
The Jiubin JB-117B Electronic Universal Testing Machine is a precision-engineered mechanical testing system designed specifically for the quasi-static tensile, compression, and bending evaluation of metallic materials under controlled loading conditions. It operates on the fundamental principle of force–displacement transduction via high-accuracy load cells and closed-loop servo-controlled electromechanical actuation, enabling precise determination of key mechanical properties—including yield strength (σy), ultimate tensile strength (σuts), elongation at break (A%), and Young’s modulus (E)—in accordance with ASTM E8/E8M, ISO 6892-1, and GB/T 228.1 standards. The system features a rigid four-column frame architecture with preloaded ball-screw transmission, ensuring minimal deflection and high axial stiffness during high-force testing up to 100 kN (configurable range). Its real-time data acquisition rate of 1 kHz supports robust capture of yield point onset—critical for identifying upper and lower yield strengths in ferritic steels and other discontinuously yielding alloys.
Key Features
- Electromechanical drive system with AC servo motor and precision planetary gearbox for smooth, low-noise operation and repeatable crosshead speed control (0.001–500 mm/min)
- High-stability dual-range load cell (e.g., 5 kN / 100 kN) with ±0.5% FS accuracy per ISO 7500-1 Class 1 certification
- Automatic extensometer interface supporting clip-on and video-based strain measurement (optional)
- Integrated digital controller with 32-bit ARM processor and embedded real-time OS for deterministic response and minimal latency
- Modular grip system compatible with wedge-action, hydraulic, and pneumatic fixtures for flat, round, and threaded specimens
- Compliance with CE Machinery Directive 2006/42/EC and RoHS 2011/65/EU; safety interlocks meet EN ISO 13857 requirements
Sample Compatibility & Compliance
The JB-117B accommodates standard metallic test specimens per ASTM E8 (tensile bars), ASTM E9 (compression cylinders), and ISO 6892-1 (flat and round coupons), with gauge lengths from 25 mm to 200 mm and cross-sectional areas ranging from 1 mm² to 500 mm². Specimen alignment is facilitated by self-centering grips and adjustable crosshead leveling. All test procedures and calibration records are traceable to CNAS-accredited national metrology institutes (e.g., SIMT, NIM). The instrument supports GLP-compliant audit trails when paired with validated software—meeting documentation requirements for ISO/IEC 17025 accredited laboratories and FDA-regulated material qualification workflows.
Software & Data Management
The proprietary Jiubin TestSuite v4.2 software provides full test method configuration, real-time curve plotting (stress–strain, force–displacement, stress–time), automated yield point detection (0.2% offset, tangent, or drop methods), and multi-curve comparative analysis. Raw data export is supported in CSV, XML, and PDF formats—with embedded metadata including operator ID, timestamp, environmental conditions (optional sensor input), and calibration certificate references. For regulated environments, optional 21 CFR Part 11 compliance modules enable electronic signatures, role-based access control, and immutable audit logs. Data integrity is preserved through SHA-256 hashing of test files and automatic backup to network-attached storage or cloud repositories (AWS S3 or Azure Blob).
Applications
- Yield strength validation of structural steels (ASTM A36, A572), aluminum alloys (AA6061-T6, AA7075-T6), and titanium grades (Ti-6Al-4V) in R&D and incoming QA
- Material certification for automotive chassis components (e.g., suspension arms, subframes) per IATF 16949 requirements
- Mechanical property benchmarking of additively manufactured metal parts (SLM, EBM) against wrought counterparts
- Quality surveillance of fasteners, springs, and wire products in production line environments
- Support for failure analysis investigations involving plastic deformation, necking behavior, and strain hardening exponent (n-value) calculation
- Teaching and methodology development in university metallurgy and mechanical engineering laboratories
FAQ
What standards does the JB-117B comply with for metallic yield strength testing?
It conforms to ASTM E8/E8M, ISO 6892-1, GB/T 228.1, and EN 10002-1 for tensile testing of metals, with optional calibration packages traceable to national standards.
Can the system perform automatic yield point detection?
Yes—via programmable algorithms including 0.2% offset, proportional limit, and upper/lower yield identification, configurable per test method.
Is third-party calibration and certification available?
Yes—Jiubin partners with ISO/IEC 17025-accredited calibration labs in China and APAC regions; certificates include as-found/as-left data and uncertainty budgets.
Does the machine support high-temperature or environmental chamber integration?
The base JB-117B is ambient-temperature rated; however, it is mechanically and electrically compatible with commercially available furnace chambers (up to 1100°C) and environmental enclosures via standardized mounting interfaces and analog I/O expansion.
How is software validation handled for regulated industries?
TestSuite v4.2 offers IQ/OQ documentation templates and can be qualified per GAMP5 guidelines; 21 CFR Part 11 modules require separate validation protocol execution by the end user or authorized service partner.
