TianYuan TY-YA300C Microcomputer-Controlled Automatic Flexural and Compressive Testing Machine

Overview

The TianYuan TY-YA300C Microcomputer-Controlled Automatic Flexural and Compressive Testing Machine is a dual-mode universal testing system engineered for standardized mechanical evaluation of cementitious materials, mortar, concrete specimens, and other quasi-brittle construction composites. It operates on the principle of controlled force application via electro-mechanical actuation—employing an AC servo motor coupled with a precision planetary gearbox and preloaded ball screw transmission—to deliver highly reproducible compressive and flexural loading profiles in strict compliance with ISO 679 and GB/T 17671-1999 (equivalent to EN 196-1). Unlike hydraulic systems, its all-electric architecture eliminates fluid maintenance, reduces ambient noise (<65 dB(A)), and ensures linear force-rate fidelity across the full operational range. The machine integrates real-time closed-loop control of load, stress, and displacement, supporting constant-rate, constant-stress, and load-hold test protocols essential for quality control laboratories operating under ISO/IEC 17025-accredited environments.

Key Features

• Electro-mechanical actuation system featuring an industrial-grade AC servo motor, high-ratio planetary reducer, and ground-precision ball screw—ensuring <±0.5% repeatability in force application and sub-micron positioning resolution.
• Microcomputer-based controller with embedded real-time OS, enabling seamless switching between compression and flexural test modes without hardware reconfiguration.
• Intuitive Windows-based software interface supporting multi-language UI (English default), customizable test templates, and direct parameter mapping to GB/T 17671, ASTM C109/C348, and ISO 679 test sequences.
• Automatic return-to-initial-position function post-test, reducing operator intervention and improving throughput in high-volume QC labs.
• Dual-stage safety architecture: hardware-level limit switches at upper/lower platen positions plus software-enforced overload cutoff (>103% of full-scale load), compliant with EN ISO 12100 functional safety requirements.
• Integrated data acquisition at 100 Hz sampling rate, capturing force, displacement, and time stamps with synchronized timestamping for audit-trail integrity.

Sample Compatibility & Compliance

The TY-YA300C accommodates standard prismatic cement mortar specimens (40 mm × 40 mm × 160 mm) for flexural testing (three-point bending, 100 mm span) and cubic or cylindrical concrete/cement specimens (e.g., 150 mm cubes) for compression. Its 150 mm diameter hardened steel platens ensure uniform stress distribution and minimal edge effects per ASTM E10 and GB/T 2611. All mechanical and software functions conform to Class 1 accuracy per GB/T 2611-2019 (equivalent to ISO 7500-1:2018), with traceable calibration certificates available upon request. The system supports GLP-compliant operation through configurable user access levels, electronic signatures, and tamper-evident audit logs—fully compatible with FDA 21 CFR Part 11 readiness when deployed with validated software configuration.

Software & Data Management

The bundled TianYuan TestMaster v4.x software provides ISO/IEC 17025-aligned data governance: automatic generation of calibrated test reports in PDF and editable Excel formats; database-backed storage with SQL Server Express backend; and role-based permissions (Operator, Supervisor, Administrator). Raw test data—including force-displacement curves, peak load annotations, modulus calculations, and failure mode flags—are stored with metadata (operator ID, environmental conditions, calibration expiry, sample ID). Export modules support CSV, XML, and ASTM E1434-compliant data exchange. Network deployment enables centralized report archiving and remote monitoring via secure HTTP(S) API endpoints—facilitating integration into LIMS or enterprise QA platforms.

Applications

• Cement and mortar strength certification per GB/T 17671-1999, ASTM C109/C348, and EN 196-1.
• Quality assurance of precast concrete elements, grouts, and repair mortars in manufacturing facilities.
• R&D validation of admixture performance, pozzolanic activity, and early-age strength development.
• Third-party inspection labs performing accredited testing for construction material certification (e.g., CE marking, CCC).
• Educational use in civil engineering laboratories for hands-on mechanics of materials instruction.

FAQ

What standards does the TY-YA300C fully comply with for cement testing?
It meets all mechanical and procedural requirements of GB/T 17671-1999 (identical to ISO 679 and EN 196-1), including loading rate tolerances, specimen geometry constraints, and data reporting formats.
Can the system be integrated into an existing LIMS environment?
Yes—via standardized ODBC/JDBC drivers and RESTful API support, enabling bidirectional data flow with major LIMS platforms including LabWare, STARLIMS, and Thermo Fisher SampleManager.
Is calibration traceability provided with the instrument?
Each unit ships with a factory calibration certificate traceable to CNAS-accredited national metrology institutes; optional annual recalibration services include uncertainty budgets per ISO/IEC 17025 Annex A.
What maintenance is required for long-term reliability?
No hydraulic fluid changes or seal replacements; recommended biannual verification of force transducer linearity and crosshead alignment using certified reference loads and optical alignment tools.
Does the software support multi-user audit trails for regulatory audits?
Yes—TestMaster v4.x maintains immutable, time-stamped records of all user actions (test initiation, parameter edits, report exports), meeting FDA 21 CFR Part 11 and EU Annex 11 electronic record requirements when configured with digital signature modules.
