Overview
The Fangyuan FY-8122 Corrugated Board Ring Crush Test Machine is an electromechanical testing system engineered for precision compression evaluation of corrugated fiberboard and related paper-based packaging materials. It operates on the principle of controlled uniaxial compressive loading applied to a standardized ring-shaped specimen—mounted vertically between parallel platens—to determine its resistance to radial collapse. This measurement directly correlates with the board’s ability to withstand stacking loads in real-world distribution environments. The instrument complies with internationally recognized standards including TAPPI T 472 (Ring Crush Test), JIS P 8126 (Compression Strength of Corrugated Fiberboard), and GB/T 2679.8 (Ring Crush Strength of Paper and Board), ensuring data compatibility across global quality assurance frameworks.
Key Features
- High-resolution load sensing via calibrated digital force transducer (1/100,000 internal resolution) ensures traceable accuracy per ISO/IEC 17025 requirements.
- Dual-range selectable capacity (100 kg or 200 kg full scale) accommodates both linerboard and heavy-duty double-wall corrugated substrates.
- Precisely regulated crosshead speed at (12.5 ± 2.5) mm/min meets standard test velocity tolerances specified in TAPPI and JIS methods.
- Rigid frame architecture with fixed lower platen and motor-driven upper platen minimizes deflection and maintains platen parallelism (<0.05 mm), critical for uniform stress distribution.
- Integrated thermal line printer provides silent, high-legibility hardcopy output without mechanical impact noise—ideal for shared laboratory environments.
- Onboard calibration verification function allows routine force value validation using certified reference weights, supporting GLP-compliant audit trails.
- Automatic overload protection halts motion upon reaching preset limits or abnormal load spikes, preserving sensor integrity and operator safety.
Sample Compatibility & Compliance
The FY-8122 accepts specimens prepared per ASTM D6342 (Standard Practice for Preparing Ring Crush Test Specimens), including 15.2 mm × 15.2 mm strips cut from linerboard, medium, or combined board. It supports multiple test configurations through interchangeable fixtures: ring crush clamp (standard), edge crush test (ECT) jig, flat crush test (FCT) assembly, and adhesive peel fixture (optional). All configurations maintain consistent platen alignment and dwell time control. The system satisfies documentation requirements under ISO 9001:2015 Clause 7.1.5 and supports compliance reporting for FDA-regulated packaging validation (21 CFR Part 11–compatible data export available via USB interface).
Software & Data Management
While operating as a standalone instrument with intuitive membrane keypad controls, the FY-8122 supports optional PC connectivity via RS-232 or USB. Its embedded firmware enables direct statistical processing—including mean, standard deviation, coefficient of variation, and max/min values—for up to 99 test records. Exported CSV files are structured for seamless import into LIMS platforms or Excel-based SPC charts. All test parameters (speed, range, dwell time, units) are stored with timestamps and user IDs, enabling full traceability required under GMP and ICH Q5E guidelines for packaging qualification studies.
Applications
- Quality control of incoming linerboard and fluting medium in corrugated converting plants.
- Validation of adhesive bond integrity in multi-ply board lamination processes.
- Development testing of recycled-content board formulations for compression performance retention.
- Third-party certification testing for ISTA 3A/3E-compliant shipping container qualification.
- Academic research on fiber orientation effects on radial compressive modulus in kraft-based composites.
- Regulatory submission support for pharmaceutical secondary packaging per USP and ISO 11607-1 Annex C.
FAQ
What standards does the FY-8122 comply with for ring crush testing?
TAPPI T 472, JIS P 8126, and GB/T 2679.8 — all implemented with hardware-level adherence to platen geometry, speed tolerance, and specimen conditioning requirements.
Can the instrument perform edge crush tests (ECT) without modification?
Yes — when equipped with the optional ECT fixture set, the same base unit executes TAPPI T 811 and ISO 3037 protocols with automatic result conversion to ECT index (N/m).
Is calibration documentation provided with the system?
Each unit ships with a factory calibration certificate traceable to NIM (China National Institute of Metrology), including as-found/as-left data and uncertainty budgets.
How is data integrity maintained during extended testing sessions?
Non-volatile memory retains all test logs even after power interruption; timestamped entries include operator ID, environmental conditions (if external hygrometer connected), and fixture identification.
Does the system support IQ/OQ protocol execution for regulated labs?
Yes — comprehensive installation and operational qualification templates are available upon request, aligned with ASTM E2500 and EU Annex 15 guidance for analytical instrumentation validation.
