Overview
The JB/YAW-2000 Automatic Compression Testing Machine is an electromechanical-hydraulic universal testing system engineered for high-accuracy, repeatable compressive strength evaluation of construction materials including concrete cubes, cement mortars, fired bricks, natural stone specimens, and precast structural elements. It operates on a closed-loop hydraulic actuation principle with real-time force feedback control, ensuring compliance with standardized loading protocols defined in ASTM C39/C39M (concrete cylinders), ASTM C109/C109M (cement mortar), ISO 7500-1 (static uniaxial compression testing machines), and GB/T 3159–2008 (Chinese national standard for electronic universal testing machines). The system integrates a high-stiffness dual-column frame, precision-machined platens, and a servo-controlled hydraulic power unit to maintain stable load application across the full 2000 kN capacity range.
Key Features
- Force-controlled closed-loop hydraulics enabling programmable load-rate profiles—either constant load rate (kN/s) or constant stress rate (MPa/s)—per ASTM E4 and ISO 5893 requirements.
- Digital load cell with 0.01 kN resolution and ≤ ±1% full-scale accuracy traceable to national metrological standards.
- Robust dual-column steel frame with 330 mm adjustable platen spacing and 370 × 370 mm hardened steel platens optimized for uniform stress distribution and minimal edge effects.
- Integrated hydraulic power unit featuring a 40 MPa rated pressure system, low-noise gear pump, and temperature-stabilized oil reservoir with filtration and level monitoring.
- Industrial-grade control cabinet with embedded PLC-based controller, analog signal conditioning modules, and isolated I/O for long-term operational reliability in QC laboratory environments.
- Pre-configured test sequences for common standards (e.g., GB/T 50081, EN 12390-3, ASTM C39), supporting both manual initiation and fully automated batch execution.
Sample Compatibility & Compliance
The JB/YAW-2000 accommodates standard cylindrical (Ø100/150 mm × 200/300 mm) and cubic (100/150/200 mm) specimens used in cementitious and masonry material certification. Its platen geometry and alignment mechanism meet ISO 7500-1 Class 1 requirements for force application accuracy and parallelism. The machine supports GLP-compliant operation through audit-trail-enabled software logging (user actions, calibration events, test parameters, raw load-displacement data), satisfying documentation expectations under ISO/IEC 17025 and internal QA procedures. All mechanical and hydraulic components conform to CE machinery directive (2006/42/EC) safety principles and are certified for use in industrial laboratories operating under ISO 9001 quality management systems.
Software & Data Management
The system ships with proprietary Windows-based testing software compatible with Windows 10/11 (64-bit), pre-installed on the supplied Lenovo desktop PC. Software features include: real-time load–displacement curve plotting with zoom/pan functionality; automatic peak detection and modulus calculation per ASTM C469; customizable report templates exportable to Excel (.xlsx), PDF, and CSV formats; digital signature support for authorized personnel; and configurable user access levels (operator, supervisor, administrator). Raw data files are stored in binary format with embedded metadata (timestamp, operator ID, environmental conditions if interfaced with optional sensors), ensuring full traceability. Exported Excel reports retain all intermediate calculations—including cross-sectional area derivation, stress-strain conversion, and statistical summaries across specimen batches—for regulatory review or third-party verification.
Applications
- Compressive strength validation of ready-mix concrete and precast concrete elements per ACI 318, EN 206, and GB 50010.
- Quality assurance testing of clay bricks, autoclaved aerated concrete (AAC) blocks, and refractory ceramics in manufacturing QC labs.
- Research-grade mechanical characterization of geopolymer binders, fiber-reinforced cement composites, and recycled aggregate concretes.
- Calibration and verification of field rebound hammers (Schmidt hammers) using reference specimens tested under controlled lab conditions.
- Third-party conformity assessment for CE marking, CCC certification, and construction material accreditation schemes.
FAQ
What standards does the JB/YAW-2000 comply with for compressive strength testing?
It meets ISO 7500-1 Class 1 accuracy requirements and supports test methods aligned with ASTM C39, ASTM C109, EN 12390-3, GB/T 50081, and GB/T 3159.
Can the machine perform flexural or tensile tests?
No—it is a dedicated compression-only system. Flexural or splitting tensile tests require separate fixtures and are not supported without hardware modification.
Is the software compliant with FDA 21 CFR Part 11 or EU Annex 11?
While it provides audit trails and electronic signatures, formal Part 11 or Annex 11 validation requires site-specific IQ/OQ/PQ documentation and is not included out-of-the-box.
What maintenance is required for long-term accuracy?
Annual recalibration of the load cell and pressure transducer is recommended; hydraulic oil replacement every 24 months or 2000 operating hours; periodic inspection of platen flatness and alignment per ISO 7500-1 Annex B.
Does the system support remote diagnostics or network integration?
Yes—the control cabinet includes Ethernet connectivity for LAN-based monitoring; optional OPC UA or Modbus TCP interfaces are available for MES/SCADA integration upon request.
