JB-126A JiuBin 5 kN Single-Column Digital Tensile Testing Machine

Overview

The JB-126A is a precision-engineered electromechanical universal testing machine designed for static mechanical property evaluation of metallic, polymeric, composite, and thin-film specimens under tension, compression, and flexure. Built upon a rigid single-column load frame with high-stiffness crosshead guidance and ball-screw-driven actuation, it delivers consistent force application and displacement control in accordance with fundamental principles of uniaxial stress–strain analysis. The system operates under closed-loop digital PID control, enabling accurate tracking of load, extension, and strain signals during quasi-static loading at rates ranging from 0.001 to 500 mm/min. Its architecture supports standardized test protocols required by materials R&D labs, quality control departments, and third-party certification bodies—particularly where compliance with ISO 6892-1 (metallic materials – tensile testing), ASTM E8/E21 (tensile tests of metallic materials), and GB/T 228.1 (Chinese national standard for metallic tensile testing) is mandated.

Key Features

• Single-column aluminum alloy frame with reinforced base plate and integrated load cell mounting—optimized for stability and minimal deflection during 5 kN maximum load application.
• Digital LCD controller with real-time display of load (N/kN), displacement (mm), strain (%), and test speed (mm/min); intuitive keypad navigation and programmable test sequences.
• High-accuracy S-type load cell calibrated to ±0.5% of full scale; resolution down to 0.1 N for low-force characterization of films, fibers, and adhesives.
• Adjustable crosshead travel range (up to 800 mm) accommodating diverse specimen geometries—from short coupons to elongated polymer strips or wire samples.
• Standardized grip interface compatible with pneumatic, wedge, and vise-type fixtures (sold separately); optional extensometer input for direct strain measurement per ASTM E83.
• Overload protection, emergency stop circuitry, and software-based limit switches ensure operator safety and equipment integrity during routine and accelerated testing cycles.

Sample Compatibility & Compliance

The JB-126A accommodates specimens conforming to standard dimensions defined in ISO 6892-1 (e.g., gauge lengths of 50 mm or 80 mm), ASTM E8 (Type A or B flat/round tensile bars), and GB/T 228.1 (P1/P2/P3 specimen types). It supports testing of metals (aluminum alloys, stainless steels), engineering plastics (PC, ABS, PA), elastomers, textiles, paperboard, and thin-film laminates. All mechanical calibrations are traceable to national metrological standards (CNAS-accredited calibration certificates available upon request). The instrument meets electromagnetic compatibility (EMC) requirements per IEC 61326-1 and electrical safety standards per IEC 61010-1, making it suitable for installation in GLP-compliant laboratories and production QA environments subject to internal audit or external accreditation (e.g., CNAS, ILAC-MRA).

Software & Data Management

While the base configuration features standalone digital control, optional PC-based software (JiuBin TestSuite™ v3.2) enables advanced data acquisition, curve fitting (Young’s modulus, yield strength, ultimate tensile strength, elongation at break), statistical reporting (CPK, X-bar R charts), and export to CSV, PDF, or XML formats. The software supports 21 CFR Part 11-compliant user access control, electronic signatures, and audit trail logging—critical for regulated industries including pharmaceutical packaging (USP , ISO 11607), medical device component validation, and automotive supplier PPAP submissions. Raw data files retain timestamped metadata including environmental conditions (if interfaced with optional temperature/humidity sensors), operator ID, and calibration history.

Applications

• Tensile property verification of raw materials and finished components in electronics manufacturing (e.g., flexible printed circuit substrates, solder joint pull tests).
• Mechanical screening of polymer films used in food packaging, battery separators, and medical pouches per ASTM D882 and ISO 527-3.
• Quality conformance testing of rubber compounds, conveyor belts, and gasket materials in automotive Tier-1 suppliers (e.g., BYD, Chery, Geely, FAW-Volkswagen).
• Research-grade characterization of nanocomposites and graphene-reinforced polymers conducted at institutions such as Beijing Graphene Institute and CAS Guangzhou Branch.
• Regulatory documentation support for FDA-submitted dossiers involving material biocompatibility and shelf-life stability (e.g., Kangmei Pharmaceutical, ZHONGJING WANXI Pharmaceutical).
• Third-party certification workflows at accredited labs including CTI, Huace Testing, and NAST, where reproducibility across multiple JB-126A units has been validated via inter-laboratory round-robin studies.

FAQ

What is the maximum test speed supported by the JB-126A?

The crosshead speed is adjustable from 0.001 mm/min to 500 mm/min, with typical tensile testing conducted between 1–100 mm/min depending on material ductility and standard requirements.
Can the JB-126A be used for compression testing?

Yes—it supports compression tests on foams, ceramics, and plastic blocks using optional flat platens and alignment fixtures compliant with ASTM D3574 and ISO 844.
Is the load cell factory-calibrated and traceable?

Each unit ships with a certificate of calibration traceable to China National Institute of Metrology (NIM); annual recalibration is recommended per ISO/IEC 17025 guidelines.
Does the system meet international regulatory requirements for GMP environments?

With optional software and documented IQ/OQ protocols, the JB-126A supports GMP-aligned validation in pharmaceutical and medical device facilities, including electronic record retention and role-based access control.
Are grips and extensometers included in the base configuration?

No—standard wedge grips and manual vise grips are available as configurable accessories; clip-on or video extensometers require separate ordering and integration verification.
