JB-WAW-100KN Hydraulic Universal Testing Machine

Overview

The JB-WAW-100KN Hydraulic Universal Testing Machine is an electro-hydraulically servo-controlled mechanical testing system engineered for high-force static mechanical characterization of metallic and composite structural materials. Designed in accordance with the fundamental principles of uniaxial tensile testing—governed by Hooke’s law, yield point determination, strain hardening behavior, and ultimate fracture analysis—it delivers repeatable force-displacement data under controlled loading rates per ISO 6892-1:2019 and GB/T 228.1–2021. This machine is specifically calibrated for standardized evaluation of reinforcing steel bars (rebar), including HRB400, HRB500, and other ASTM A615/A706-compliant grades, enabling precise measurement of yield strength (Rp0.2), tensile strength (Rm), elongation at break (Agt), and uniform elongation (Ag). Its rigid four-column frame, high-stiffness load train, and dual-range load cell architecture ensure minimal compliance error and high reproducibility across extended test cycles.

Key Features

• Electro-hydraulic servo control system with closed-loop feedback for accurate load and displacement regulation across 0.005–500 mm/min crosshead speed range
• 100 kN maximum rated capacity with dual-range load cell (±0.5% FS accuracy per ISO 7500-1 Class 1)
• Adjustable test space accommodating specimens up to 600 mm gauge length and 32 mm diameter (standard rebar sizes Ø6–Ø32 mm)
• Integrated extensometer interface supporting clip-on and video-based strain measurement (optional)
• Hydraulic clamping system with self-aligning wedge grips, capable of maintaining constant grip pressure during high-load tensile tests
• Real-time synchronization of load, displacement, and strain signals at 100 Hz sampling rate, compliant with ASTM E1012 requirements for system alignment verification

Sample Compatibility & Compliance

The JB-WAW-100KN supports standardized specimen geometries defined in ISO 6892-1 Annex A (flat and round tensile specimens) and GB/T 228.1 Annex B (rebar-specific parallel section dimensions). It accommodates hot-rolled deformed steel bars, welded wire mesh, prestressed strands, and cold-drawn steel wires. All mechanical test procedures align with national and international regulatory frameworks: mandatory conformance to China’s GB 1499.2–2018 for ribbed steel bars; full traceability to ASTM A615/A615M, ASTM A706, EN 10080, and ISO 15630-1. The system meets GLP audit requirements through configurable user access levels, electronic signature support, and time-stamped test log archiving—fully compatible with FDA 21 CFR Part 11 when deployed with validated software modules.

Software & Data Management

The embedded Windows-based control and analysis software provides ISO/IEC 17025-aligned test sequence definition, real-time stress–strain curve rendering, and automated parameter extraction (yield offset, UTS, modulus, reduction of area). Raw data are stored in encrypted binary format with metadata tagging (operator ID, calibration certificate ID, environmental conditions). Export options include PDF test reports with digital signatures, Excel-compatible .csv files, and XML-based data interchange compliant with ASTM E1447. Audit trail functionality records all user actions—including method edits, result overrides, and calibration events—with immutable timestamps and operator attribution, satisfying internal quality audits and third-party accreditation bodies such as CNAS and ILAC-MRA signatories.

Applications

This system serves as a primary verification tool in R&D laboratories, third-party testing institutes, and manufacturing QA/QC departments. Typical use cases include: mechanical certification of construction-grade rebar prior to civil infrastructure deployment; comparative fatigue pre-screening via monotonic tensile preconditioning; validation of thermomechanical processing parameters (e.g., quenching & self-tempering); evaluation of corrosion-influenced ductility loss in chloride-exposed specimens; and interlaboratory round-robin studies coordinated under CNAS proficiency testing schemes. End-user sectors span structural engineering contractors, steel producers (e.g., Baosteel, Shougang), automotive chassis component suppliers (BYD, Geely, Chery), railway infrastructure developers, and pharmaceutical packaging material testers requiring tensile integrity assessment of aluminum laminates.

FAQ
