JB-118 Universal Testing Machine (UTM) – JiuBin Instruments

Overview

The JB-118 Universal Testing Machine (UTM) is an electromechanical static testing system engineered for precision tensile, compression, flexural, and peel testing of metallic, polymeric, composite, and elastomeric materials. Designed in accordance with fundamental principles of mechanical metrology, the system employs a high-rigidity dual-column frame, servo-controlled AC motor drive, and closed-loop load/displacement feedback to ensure traceable force measurement and repeatable kinematic control. Its modular architecture supports standardized test configurations per ASTM E4, ASTM E8/E8M, ISO 6892-1, and GB/T 228.1—enabling compliance-critical validation in R&D laboratories, quality control departments, and third-party certification facilities.

Key Features

• Electromechanical actuation system with digital servo control for smooth, low-noise operation across full stroke range
• High-accuracy load cell calibrated to ±0.5% of full scale (FS), traceable to national metrological standards
• Adjustable crosshead travel (up to 1,200 mm standard) with fine-positioning capability via incremental encoder feedback
• Interchangeable grip systems: wedge-action clamps for metallic specimens, pneumatic grips for films/tubes, and custom fixtures for pulley assemblies, aluminum plates, and rubber hoses
• Integrated safety interlocks including emergency stop, overload cut-off, and mechanical limit switches compliant with ISO 13857
• Real-time data acquisition at ≥1 kHz sampling rate, supporting dynamic response analysis for quasi-static loading protocols

Sample Compatibility & Compliance

The JB-118 accommodates diverse specimen geometries—including flat aluminum plates (0.5–10 mm thick), reinforced rubber hoses (ID 6–50 mm), multi-sheave pulley blocks, and laminated composites—via configurable jaw profiles and axial alignment fixtures. It meets essential regulatory requirements for material verification in regulated environments: test methods are documented per ISO/IEC 17025, and raw data integrity conforms to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate). While not pre-certified for FDA 21 CFR Part 11, the system supports audit-ready reporting when paired with validated third-party software meeting electronic record retention criteria.

Software & Data Management

The machine operates with JiuBin’s proprietary UTMControl v3.2 software, providing intuitive test method setup (tensile, compression, bend, shear), real-time curve visualization (stress–strain, load–displacement), and automated calculation of key mechanical properties—including yield strength (Rp0.2), ultimate tensile strength (Rm), elongation at break (A%), modulus of elasticity (E), and secant modulus. Export formats include CSV, XML, and PDF reports with embedded metadata (operator ID, timestamp, calibration certificate ID). Raw data files retain unprocessed sensor outputs for reanalysis; all modifications are logged with user attribution and timestamp per GLP/GMP-aligned audit trail protocols.

Applications

• Mechanical characterization of structural aluminum alloys used in automotive chassis components (e.g., pulley mounting brackets)
• Validation of hose reinforcement integrity under sustained pressure cycling and axial pull-out conditions
• Quality assurance testing of bonded interfaces in laminated polymer–metal hybrid panels
• Educational mechanics labs: demonstration of Hooke’s law, necking behavior, and ductile-to-brittle transition
• Supplier qualification per OEM specifications (e.g., BYD, Geely, Chery) requiring tensile performance documentation per ISO 10360-2
• Regulatory submission support for medical device packaging (e.g., blister seal strength per ASTM F88) and pharmaceutical film integrity (per USP )

FAQ

What is the maximum rated load capacity of the JB-118?

The standard configuration supports up to 100 kN; higher-capacity variants (200 kN, 300 kN) are available upon request with structural reinforcement and recalibrated transducers.
Does the system support high-temperature testing?

No—this model is designed for ambient-temperature static mechanical testing only. High-temperature extensometry or environmental chambers require external integration and are not included in base configuration.
Can test methods be exported and shared across laboratories?

Yes—UTMControl v3.2 allows saving and importing method templates (.utm files), ensuring consistent parameterization (crosshead speed, preload, hold time) across multi-site deployments.
Is third-party calibration certification provided?

JiuBin supplies factory calibration certificates traceable to CNAS-accredited reference standards; on-site calibration by ISO/IEC 17025 accredited providers is recommended annually.
How is mechanical alignment verified prior to testing?

The system includes built-in parallelism check tools and alignment gauges; users are advised to perform routine verification using ASTM E1012-compliant procedures before critical qualification runs.
