YANRUN MC009 Series Microcomputer-Controlled Electro-Hydraulic Servo Universal Testing Machine WAW-1000C

Overview

The YANRUN MC009 Series Microcomputer-Controlled Electro-Hydraulic Servo Universal Testing Machine (Model WAW-1000C) is a high-capacity, precision-engineered static mechanical testing system designed for standardized tensile, compression, bending, and shear testing of metallic and non-metallic materials in accordance with international test standards including ASTM E4, ASTM E8/E8M, ISO 6892-1, ISO 7500-1, and GB/T 228.1. Utilizing a closed-loop electro-hydraulic servo control architecture, the system delivers stable force application through a high-response servo valve-controlled hydraulic actuation system. The machine features a four-column, bottom-mounted hydraulic cylinder configuration with upper tensile zone and lower compression/bending workspace—optimized for ergonomic sample handling and compatibility with auxiliary equipment such as high-temperature furnaces and environmental chambers. Force transduction is achieved via a calibrated load cell integrated into the load train, while displacement and deformation are measured using high-resolution linear variable differential transformers (LVDTs) and extensometers compliant with Class 1 or Class 0.5 accuracy per ISO 7500-1.

Key Features

• Four-column, bottom-actuated frame architecture with rigid cast-iron base and reinforced crosshead structure for minimal deflection under full-load conditions
• Electro-hydraulic servo control enabling precise regulation of test parameters—including constant-rate force, constant-rate displacement, and constant-rate strain modes
• High-fidelity analog-to-digital conversion with 1/500,000 internal resolution; full-scale measurement without range switching ensures consistent accuracy across the entire 2%–100% FS operating envelope
• Dual protection system: hardware-based overload cutoff (triggered at >103% of maximum rated load) and mechanical stroke limit switch to prevent cylinder overtravel
• Integrated hydraulic clamping system with automatic pressure maintenance during hold phases—eliminating manual re-tightening and ensuring specimen integrity throughout extended tests
• Modular test space design: adjustable crosshead height in three discrete zones (up to 2600 mm total height), supporting high-temperature furnace integration and large-format specimen testing
• Standardized interface for third-party extensometers, video extensometers, and digital image correlation (DIC) systems

Sample Compatibility & Compliance

The WAW-1000C accommodates a broad spectrum of specimen geometries and material classes. Round specimens ranging from Φ13 mm to Φ60 mm and flat specimens up to 40 mm thick can be securely gripped using hydraulically actuated wedge-type jaws. Bending fixtures support span lengths up to 450 mm and roller diameters of Φ30 mm, meeting ASTM E290 and ISO 7438 requirements. All mechanical components comply with ISO 12100 (safety of machinery) and CE Machinery Directive 2006/42/EC. Force calibration traceability is maintained to national metrological standards (e.g., NIM China, NIST-traceable equivalents), and the system supports audit-ready documentation for GLP and GMP environments when paired with validated software.

Software & Data Management

Control and data acquisition are managed via YANRUN’s proprietary TestMaster v5.x software suite, compatible with Windows 10/11 (64-bit). The platform implements real-time PID parameter tuning, multi-channel synchronized sampling (≥1 kHz), and automated test sequence scripting. Raw data—including force, displacement, strain, time, and user-defined channels—is stored in binary .tdm format with embedded metadata (operator ID, sample ID, environmental conditions, calibration timestamps). Export options include CSV, Excel, and XML for LIMS integration. Software validation packages—including IQ/OQ documentation, electronic signature support, and 21 CFR Part 11-compliant audit trails—are available upon request for regulated laboratories.

Applications

This system serves as a primary mechanical characterization tool in R&D, quality assurance, and certification labs across multiple sectors: structural steel evaluation for civil engineering projects; high-strength alloy validation in aerospace component manufacturing; composite laminate interlaminar shear strength assessment; geotechnical material testing (concrete, asphalt, soil-cement); and advanced material development (shape-memory alloys, metal matrix composites). Its robust architecture and wide dynamic range make it suitable for both routine compliance testing and exploratory mechanical behavior studies under controlled thermal or environmental conditions.

FAQ

What standards does the WAW-1000C comply with for force measurement accuracy?
Per ISO 7500-1:2018, the system achieves Class 1 or optional Class 0.5 verification status, with load accuracy specified as ±1% or ±0.5% of full scale, depending on configuration and calibration protocol.
Can the system perform strain-controlled testing with extensometers?
Yes—the controller supports direct feedback from clip-on or non-contact extensometers, enabling true strain-controlled ramping and hold protocols per ASTM E2309 and ISO 6892-1 Annex C.
Is remote diagnostics and firmware update capability supported?
Standard Ethernet connectivity enables secure remote access via SSH or VNC for technical support; firmware updates are delivered through signed package files with SHA-256 verification.
What is the maximum recommended piston travel speed during high-force compression tests?
The nominal maximum piston speed is 50 mm/min; however, for tests exceeding 800 kN, operation above 20 mm/min is not recommended to maintain hydraulic stability and thermal equilibrium in the oil circuit.
Does the system meet requirements for ISO/IEC 17025 accredited testing laboratories?
When operated with documented calibration procedures, certified reference standards, and version-controlled software, the WAW-1000C satisfies the technical competence criteria outlined in ISO/IEC 17025:2017 Clause 6.4 (Equipment) and Clause 7.7 (Ensuring validity of results).
