Overview
The JB-WAW-600 Hydraulic Universal Testing Machine is a precision-engineered static mechanical testing system designed for high-force tensile, compressive, and bending evaluations of structural metallic materials—particularly deformed steel bars (rebar) used in reinforced concrete construction. Built on a robust dual-column hydraulic loading frame with a rigid cast-iron base and reinforced crosshead, the system operates on a closed-loop servo-controlled hydraulic actuation principle. Force application is regulated via a proportional electro-hydraulic servo valve, enabling precise control of loading rate, hold duration, and displacement trajectory per ISO 6892-1, ASTM E8/E21, and GB/T 228.1 standards. The machine delivers a maximum test capacity of 600 kN (60 tons), making it suitable for Grade III, IV, and V deformed rebar (e.g., HRB400, HRB500, HRBF500) with nominal diameters ranging from 6 mm to 40 mm.
Key Features
- Electro-hydraulic servo control system with real-time feedback loop for force, displacement, and strain synchronization
- Dual-column heavy-duty frame with preloaded spherical seat design to minimize alignment errors and ensure axial load fidelity
- High-accuracy load cell calibrated to ±0.5% of full scale (FS), traceable to CNAS-accredited national metrology institutes
- Integrated digital extensometer interface supporting automatic yield point detection (upper/lower yield strength), uniform elongation (Ag), and total elongation at maximum force (Agt) per ISO 6892-1 Annex B
- Hydraulic wedge-type grips with serrated jaw faces and adjustable clamping pressure for secure specimen retention during high-stress tensile rupture
- Emergency stop circuit compliant with IEC 60204-1; overload protection set at 105% FS with mechanical and electronic redundancy
Sample Compatibility & Compliance
The JB-WAW-600 accommodates standard cylindrical and flat tensile specimens conforming to ISO 6892-1, ASTM E8M, and GB/T 228.1 geometries—including round rebar samples prepared per GB/T 2975 (transverse sampling from rolled products). Specimen gripping length is adjustable up to 200 mm, and extensometer gauge lengths support 50 mm, 100 mm, and 200 mm configurations. All mechanical test reports generated meet GLP documentation requirements, with audit trails enabled for data integrity verification. The system supports compliance workflows aligned with ISO/IEC 17025:2017 (Clause 7.7) for accredited testing laboratories and satisfies mandatory mechanical property verification under China’s GB 1499.2–2018 for hot-rolled ribbed steel bars.
Software & Data Management
Control and analysis are performed using the proprietary Jiubin TestMaster v3.2 software suite, a Windows-based platform compliant with FDA 21 CFR Part 11 for electronic records and signatures (user authentication, role-based access, audit trail logging, and electronic signature capture). The software provides real-time curve plotting (stress–strain, load–displacement), automated calculation of tensile strength (Rm), yield strength (ReH/ReL), elongation after fracture (A), and reduction of area (Z). Raw data export is supported in CSV, XML, and PDF formats, with optional integration into LIMS via OPC UA or ODBC protocols. Calibration certificates include uncertainty budgets calculated per GUM (JCGM 100:2008).
Applications
- Tensile property validation of hot-rolled deformed steel bars for civil infrastructure projects
- Quality assurance testing in rebar manufacturing plants and third-party inspection agencies
- Research on strain-hardening behavior and necking onset in high-strength low-alloy (HSLA) steels
- Comparative evaluation of post-yield ductility across different heat treatment conditions
- Compliance testing for bidding documents requiring ISO/ASTM/GB-certified mechanical data packages
- Calibration verification of portable hardness testers using reference tensile specimens
FAQ
What standards does the JB-WAW-600 support for rebar tensile testing?
It fully supports ISO 6892-1:2019, ASTM E8/E21, GB/T 228.1–2021, and GB 1499.2–2018 for geometry, procedure, and reporting.
Is the system compatible with extensometers from third-party manufacturers?
Yes—via standardized analog voltage (±10 V) and digital RS-422 interfaces; compatibility confirmed for ZWICK, MTS, and Tinius Olsen extensometers.
Does the software provide audit-trail functionality required for ISO/IEC 17025 accreditation?
Yes—TestMaster v3.2 logs all user actions, parameter changes, calibration events, and report generation with timestamped, non-erasable entries.
What is the typical lead time for factory calibration and installation support?
Standard delivery includes pre-shipment calibration; on-site commissioning and operator training are available within 10 business days of order confirmation.
Can the JB-WAW-600 perform compression tests on concrete cylinders or metal blocks?
Yes—equipped with flat platens (Φ300 mm) and optional compression fixtures; maximum compressive load capacity remains 600 kN with displacement resolution of 0.001 mm.
