Overview
The JB-117A Universal Tensile Testing Machine is an electromechanical static testing system engineered for high-reproducibility mechanical characterization of polymeric wires, insulated cables, thermoplastic and thermoset composites, elastomeric sheaths, and fiber-reinforced polymer (FRP) specimens. It operates on the principle of controlled displacement-driven uniaxial tension, employing a precision ball-screw actuator and closed-loop load cell feedback to maintain force or displacement control per ISO 17961 and ASTM E4 standards. Designed for laboratory and quality control environments, the system delivers traceable, repeatable measurements of tensile strength, elongation at break, yield point, modulus of elasticity (Young’s modulus), and stress–strain curve linearity across standard crosshead speeds from 0.001 mm/min to 500 mm/min. Its rigid dual-column frame with reinforced aluminum alloy crosshead minimizes deflection under maximum 50 kN load, ensuring geometric stability during high-force tests on armored cables or extruded polymer profiles.
Key Features
- High-accuracy load measurement via calibrated S-type load cell with ±0.5% full-scale accuracy—certified per ISO 7500-1 Class 0.5
- Electromechanical servo drive system with integrated encoder feedback for precise crosshead positioning and speed control
- Dual-column structural design with 1,200 mm effective test height and 450 mm depth throat clearance—accommodates full-length cable reels and bundled multi-conductor samples
- Modular gripping interface supporting pneumatic, wedge, and hydraulic clamps; optional high-temperature grips (up to 200 °C) and environmental chambers available
- Compliance-ready firmware architecture supporting audit trails, user access levels, and electronic signatures in accordance with FDA 21 CFR Part 11 and GLP/GMP requirements
- Integrated overload protection, emergency stop circuitry, and mechanical limit switches meeting IEC 61800-5-2 functional safety guidelines
Sample Compatibility & Compliance
The JB-117A accommodates standardized specimen geometries per ASTM D638 (Type I–V plastics), ASTM D882 (thin films and sheets), ISO 527-2 (rigid plastics), and IEC 60811-501 (electric cable insulation). It supports direct testing of stranded copper/aluminum conductors, PVC/NBR/LSZH jacketed cables, silicone rubber insulators, cross-linked polyethylene (XLPE) sheaths, and carbon-fiber-reinforced polymer (CFRP) tapes. All test methods are pre-configured in software to align with ISO/IEC 17025-accredited laboratories’ validation protocols. The instrument meets CE marking requirements under Machinery Directive 2006/42/EC and electromagnetic compatibility per EN 61326-1.
Software & Data Management
Equipped with Jiubin TestSuite™ v4.2, the system provides real-time force–displacement curve acquisition, automatic yield detection (0.2% offset method), modulus calculation (secant/tangent), and statistical reporting per ISO 5725. Raw data export is supported in CSV, XML, and PDF formats with embedded metadata (operator ID, timestamp, calibration certificate ID, environmental conditions). Audit logs record all parameter changes, test starts/stops, and report generations—retained for ≥36 months. Optional cloud synchronization enables remote monitoring and centralized database integration with LIMS platforms via OPC UA or RESTful API.
Applications
- Quality assurance of insulated power cables per IEC 60502 and GB/T 12706
- Tensile performance evaluation of automotive wiring harnesses (e.g., LV112, USCAR-21)
- Mechanical validation of medical-grade polymer tubing (ISO 10993-12 compliant sample prep)
- R&D testing of biodegradable packaging films and recyclable thermoplastic elastomers
- Failure analysis of aged cable insulation exposed to thermal cycling or UV degradation
- Validation of adhesion strength between conductor and dielectric layers using peel or pull-out configurations
FAQ
What international standards does the JB-117A support out-of-the-box?
ASTM D638, ASTM D882, ISO 527, GB/T 1040, GB/T 16491, IEC 60811-501, and ISO 7500-1 Class 0.5 calibration compliance are preloaded in the test method library.
Can the system be validated for GMP-regulated environments?
Yes—TestSuite™ v4.2 includes 21 CFR Part 11-compliant features: role-based access control, electronic signatures, and immutable audit trails required for pharmaceutical and medical device QC labs.
Is third-party calibration certification included?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China) and optionally available with UKAS or DAkkS-accredited calibration upon request.
What is the typical lead time for custom grip solutions?
Standard pneumatic grips ship within 5 business days; custom-designed grips (e.g., for irregular cable bundles or high-temp applications) require 12–18 working days after drawing approval.
Does the machine support multi-step cyclic loading protocols?
Yes—via programmable test sequences including hold, ramp, and step-load modes, enabling fatigue pre-conditioning and creep testing per ISO 899-1.
