Overview
The YANRUN WAW-1000B Electro-Hydraulic Servo Universal Testing Machine is a high-capacity, dual-column universal testing system engineered for precision mechanical property evaluation of metallic, composite, and high-strength structural materials under quasi-static loading conditions. Based on closed-loop electro-hydraulic servo control architecture, the machine employs a low-inertia servo valve, high-bandwidth hydraulic actuation system, and a high-resolution 24-bit A/D conversion module (1/500,000 full-scale resolution, unsegmented across the entire force range) to ensure stable load application and exceptional repeatability. Its lower-mounted hydraulic cylinder configuration optimizes structural rigidity and minimizes bending moments during compression and bending tests—critical for maintaining ASTM E4 and ISO 7500-1 Class 0.5 compliance in force measurement accuracy. Designed for integration into quality control laboratories, R&D centers, and accredited material testing facilities, the WAW-1000B supports standardized tensile, compression, bending, and shear test protocols per ASTM E8/E9/E290/E211, ISO 6892-1, GB/T 228.1, and EN 10002-1.
Key Features
- Lower-mounted hydraulic actuator with reinforced C-frame structure for enhanced column alignment and reduced parasitic bending during high-load compression tests.
- Closed-loop servo control system enabling precise regulation of load, displacement, and strain at rates from 0.001 mm/min to 50 mm/min, with dynamic response optimized for both slow-rate ductility assessment and rapid yield-point capture.
- High-fidelity force transduction via a calibrated load cell with verified linearity ≤±0.05% FS and thermal drift compensation over 10–40 °C ambient range.
- Dual-mode hydraulic clamping: automatic pressure modulation ensures consistent grip stress across specimen geometries (round: Φ13–Φ60 mm; flat: up to 30 mm thick), minimizing slippage and premature failure at jaws.
- Integrated mechanical safety interlocks—including overload cutoff, stroke limit switches, and emergency hydraulic dump valves—compliant with ISO 12100 and EN 60204-1 machinery safety directives.
- Modular color customization for host frame (RAL-coded options) to support lab-wide equipment identification and facility-specific safety zoning requirements.
Sample Compatibility & Compliance
The WAW-1000B accommodates standard and non-standard specimens per ISO 6892-1 (tensile), ISO 7500-1 (calibration), ISO 15630-1 (reinforcing steel), and ASTM A370 (steel products). Its 700 mm tensile gap and 600 mm compression height support full-length coupon testing for structural beams, weld joints, and cast components. The 350 mm adjustable bend span and Φ30 mm support rollers meet ISO 7438 and ASTM E290 specifications for transverse bending of plates and bars. All force, displacement, and deformation channels are traceably calibrated to national metrology standards (CNAS-accredited calibration certificates available upon request). System-level validation satisfies GLP audit requirements for data integrity, including electronic signature support and 21 CFR Part 11–compatible user access controls when paired with optional software modules.
Software & Data Management
Control and analysis are executed via YANRUN’s proprietary TESTMaster v4.2 software suite—Windows-based, multi-language compatible, and compliant with IEC 62591 (WirelessHART) and OPC UA 1.04 for enterprise-level SCADA integration. Real-time acquisition captures ≥1,000 data points/sec across synchronized force, displacement, and extensometer channels. Automated test sequence scripting supports multi-step protocols (e.g., preload → ramp → hold → unload → re-ramp) with conditional branching based on real-time parameter thresholds. Raw data exports in ASTM E1435-compliant .tdms and .csv formats include embedded metadata (operator ID, calibration expiry, environmental logs). Audit trail functionality records all user actions, parameter modifications, and calibration events with time stamps and digital signatures—fully auditable for ISO/IEC 17025 accreditation reviews.
Applications
- Mechanical characterization of high-strength steels (e.g., S690QL, ASTM A514) used in offshore platforms and bridge girders.
- Compression testing of concrete-filled steel tubes (CFST), precast concrete segments, and geopolymer composites per EN 12390-3.
- Bending fatigue pre-screening of railway axle materials under ISO 13584-301-defined load spectra.
- Qualification testing of welded joints per AWS D1.1 and ISO 15614-1, including macro/micro hardness correlation with tensile strength.
- Validation of additive manufacturing (AM) metal parts (Ti-6Al-4V, Inconel 718) against AMS 4999 and ASTM F3001 mechanical property requirements.
- Research-grade cyclic loading experiments (e.g., ratcheting, creep–fatigue interaction) using custom waveform generation and hold-time control.
FAQ
What international standards does the WAW-1000B comply with for force measurement accuracy?
The system meets ISO 7500-1 Class 0.5 and ASTM E4 requirements for static force verification, with factory-certified calibration valid for 12 months under normal operating conditions.
Can the machine perform strain-controlled tests using an extensometer?
Yes—equipped with analog and digital extensometer interfaces (LVDT and video-based options supported), enabling closed-loop strain control down to 0.005 mm resolution per ISO 9513.
