Overview
The YANRUN WAW-600B is a microcomputer-controlled electro-hydraulic servo universal testing machine engineered for high-precision mechanical property evaluation of metallic, composite, and structural materials under tension, compression, bending, and shear loading conditions. It operates on the principle of closed-loop hydraulic force actuation, where a high-stability servo valve regulates oil flow to a double-acting piston cylinder, enabling precise load and displacement control in accordance with ISO 7500-1, ASTM E4, and GB/T 228.1 standards. The system integrates a calibrated oil-pressure load cell, a high-resolution displacement transducer (0.01 mm resolution), and an extensometer-ready interface supporting standard 50 mm gauge length measurements up to 10 mm total deformation. Designed for laboratory and industrial QA/QC environments, the WAW-600B delivers full-scale force accuracy of ±0.5% FS across its 12 kN–600 kN operational range — meeting requirements for accredited material certification and routine compliance verification.
Key Features
- Electro-hydraulic servo architecture with real-time PID control for simultaneous load, displacement, and strain regulation
- Hydraulic wedge-type clamping system ensuring uniform stress distribution and minimal slippage during high-force tensile tests (e.g., rebar, structural steel)
- Dual-range load measurement: optimized sensitivity at low loads (12 kN minimum) and stability at peak capacity (600 kN)
- Programmable test profiles including ramp, hold, cyclic, and multi-step sequences via embedded Windows-based control software
- Integrated PC-mounted programmable amplifier with automatic zeroing, gain calibration, and thermal drift compensation
- Robust mechanical frame with 1800 kg mass and rigid column design minimizing deflection and enhancing repeatability
- Modular extensometer interface compliant with ASTM E83 Class B-2 requirements for axial strain measurement
Sample Compatibility & Compliance
The WAW-600B accommodates standardized flat specimens (0–15 mm thickness) and round bars (φ13–φ40 mm), including deformed reinforcing steel per ISO 6935-2 and ASTM A615. Its φ160 mm compression platen and 400 mm adjustable bend support span meet ISO 37, ASTM C39, and GB/T 232 specifications. All hardware and firmware comply with CE machinery directive 2006/42/EC, and the control system supports audit-trail-enabled operation aligned with GLP and ISO/IEC 17025 documentation requirements. Force calibration traceability is maintained to national metrology institutes via factory-certified load cell calibration certificates (valid for 12 months).
Software & Data Management
The proprietary YANRUN TestMaster™ software provides intuitive graphical test setup, real-time curve visualization (load vs. displacement, stress vs. strain), and automated report generation in PDF/Excel formats. It supports user-defined parameter templates, digital signature authentication, and data encryption per ISO/IEC 27001 guidelines. Raw data files are stored in ASCII-delimited format for third-party analysis (e.g., MATLAB, Python Pandas). Software versioning, user role management (admin/operator/viewer), and electronic record retention align with FDA 21 CFR Part 11 principles for regulated environments requiring data integrity and accountability.
Applications
- Tensile testing of carbon steel, stainless steel, aluminum alloys, and prestressed concrete reinforcement
- Compression testing of concrete cylinders (up to 300 mm height), cement mortars, and polymer composites
- Three-point bending evaluation of beams and structural profiles per ISO 178
- Proof load verification and yield strength determination for fasteners and welded joints
- Quality conformance testing in foundries, rolling mills, and precast concrete manufacturing facilities
- Educational use in university materials science laboratories for ASTM E8/E9 methodology instruction
FAQ
What standards does the WAW-600B support for force calibration and test execution?
ISO 7500-1 (class 1), ASTM E4, GB/T 228.1, and EN 10002-2 are fully supported through hardware design, sensor linearity, and software test method libraries.
Can the system be integrated into a LIMS or MES environment?
Yes — optional OPC UA and Modbus TCP communication modules enable bidirectional data exchange with enterprise-level laboratory and manufacturing systems.
Is extensometer compatibility included as standard or optional?
Extensometer mounting brackets and analog signal input channels are built-in; the extensometer itself is selected separately based on gauge length and resolution requirements.
What maintenance intervals are recommended for hydraulic oil and filter replacement?
YANRUN specifies 12-month or 2000-hour service intervals for hydraulic oil (ISO VG 46 anti-wear type) and inline filter elements, documented in the maintenance logbook provided with each unit.
Does the system support cyclic fatigue testing?
While primarily configured for static and quasi-static tests, the WAW-600B can perform low-cycle fatigue (LCF) up to 5 Hz with optional high-response servo valve and custom waveform programming in TestMaster™.
