Overview
The Tuofeng YAW-2000D and YAW-3000 are fully automated hydraulic compression testing machines engineered for high-precision mechanical property evaluation of construction materials—including concrete cubes, mortar specimens, bricks, and precast structural elements. These systems operate on the principle of controlled quasi-static axial compression, utilizing a closed-loop servo-hydraulic actuation architecture to maintain precise load or stress rate profiles per ASTM C39/C39M, ASTM C109/C109M, ISO 7500-1, and GB/T 2611. The core measurement chain integrates a high-stability pressure transducer, precision analog signal conditioning, and a 24-bit A/D converter with no range switching—ensuring linearity and repeatability across the entire 5–100% test force span. Real-time force feedback is processed via PID-based digital control algorithms executed within the embedded measurement firmware, enabling stable ramp-and-hold loading sequences essential for compliance with ISO 16840 and EN 12390-3.
Key Features
- Fully integrated servo-hydraulic actuation system featuring a high-response digital servo valve, enabling programmable load rate control from 0.05 to 10 kN/s with <±1% deviation from setpoint
- Robust dual-column frame with 260 mm column spacing and 320 mm vertical platen clearance—optimized for standard and oversized civil engineering specimens
- Φ300 mm hardened steel platens with self-centering geometry and surface flatness ≤ 0.02 mm/m, conforming to ASTM E10 and ISO 7500-1 platen requirements
- Dual-mode control capability: constant load rate (kN/s) or constant stress rate (MPa/s), both configurable via software interface with real-time validation
- Hardware-level overload protection: automatic pump shutdown triggered at >103% of full-scale capacity, independent of software execution
- Embedded data acquisition at ≥1 kHz sampling rate, supporting dynamic event capture during brittle failure transitions
Sample Compatibility & Compliance
The YAW-2000D/YAW-3000 accommodates standardized compressive test specimens per ASTM C39 (150 mm × 300 mm concrete cylinders), ASTM C109 (50 mm cubes), EN 12390-3 (150 mm cubes), and GB/T 50081 (100/150/200 mm cubes). Specimen height-to-diameter ratios up to 2.0 are supported within the 260 mm platen gap. All mechanical and metrological performance parameters comply with Class 1 accuracy requirements per ISO 7500-1:2018 and verification protocols aligned with ISO/IEC 17025 for accredited testing laboratories. The system supports audit-ready operation under GLP and GMP environments, with optional configuration for 21 CFR Part 11-compliant electronic signatures and immutable audit trails.
Software & Data Management
The bundled Windows-based testing software provides ISO/IEC 17025-aligned workflow management: specimen registration, test method selection (e.g., “Concrete Cube Compression – GB/T 50081”), parameter presetting, real-time curve visualization (force vs. displacement/time), auto-calculated strength values (MPa), and customizable reporting templates exportable to PDF, Excel, and XML. Raw data files (.tdms) retain full-resolution time-series records including force, displacement, and system status flags. Data integrity safeguards include write-once storage mode, user role-based access control (operator, supervisor, administrator), and timestamped change logs meeting traceability requirements for third-party accreditation audits.
Applications
- Compressive strength determination of Portland cement concrete, high-performance concrete, and fiber-reinforced composites
- Quality control testing in ready-mix plants, precast facilities, and material certification labs
- Research-grade mechanical characterization for cementitious material development and admixture evaluation
- Structural component validation per JGJ/T 70 (China), BS EN 12390-3 (UK/EU), and ACI 214R (USA)
- Calibration reference machine for secondary force calibration of lower-capacity testers (up to 300 kN)
FAQ
What standards does this machine support for calibration and verification?
It complies with ISO 7500-1:2018 for static force measurement systems and supports verification procedures per JJG 139–2014 (China), ASTM E4, and EN ISO 376.
Can the system perform multi-step loading protocols (e.g., hold-and-reload cycles)?
Yes—the software supports user-defined multi-segment loading profiles, including ramp-hold-ramp sequences with programmable dwell times and load thresholds.
Is remote diagnostics or firmware update capability available?
Firmware updates are performed via secure USB transfer; remote desktop-assisted diagnostics can be enabled under IT-administered network policies.
What maintenance intervals are recommended for hydraulic oil and filters?
Hydraulic oil should be replaced every 2,000 operating hours or biannually; high-pressure filter elements require replacement every 1,000 hours or annually, whichever occurs first.
Does the system meet electromagnetic compatibility (EMC) requirements for laboratory deployment?
Yes—it conforms to IEC 61326-1:2013 for EMC in laboratory environments and carries CE marking under the EU Machinery Directive 2006/42/EC.
