Overview
The GOTECH GT-6011-B Microcomputer-Controlled Ring Crush Tester is a precision-engineered instrument designed specifically for determining the ring crush strength (RCT) of corrugated board components—including linerboard, medium (fluting paper), and kraft liner—per ASTM D638, ISO 12192, TAPPI T818, and GB/T 2679.8 standards. It operates on the principle of axial compression applied to a cylindrical specimen formed from a strip of paper or board, with force measured until catastrophic buckling occurs. The test delivers critical mechanical data essential for predicting edge crush resistance (ECT) and correlating with box compression strength—key performance indicators in packaging integrity assessment and supply chain durability validation. Engineered for repeatable, operator-independent results, the GT-6011-B integrates closed-loop load control, real-time displacement tracking, and digital calibration traceability compliant with ISO/IEC 17025 requirements for testing laboratories.
Key Features
- Microprocessor-based control system with intuitive LCD interface and built-in memory for up to 200 test records
- High-precision load cell with ±0.5% full-scale accuracy and automatic zero-point compensation
- Adjustable platen speed (0.1–10 mm/min) to meet multiple standard protocols including TAPPI and ISO ramp rates
- Dual-column rigid frame construction ensuring minimal deflection during high-load testing (max. 1000 N capacity)
- Standardized 15.2 mm inner diameter ring-forming mandrel and conforming anvil geometry per TAPPI T818 specifications
- Automatic peak-hold function with audible alert upon rupture detection and programmable pre-load stabilization
- RS-232 serial port for direct connection to external PCs; optional USB-to-serial adapter support
Sample Compatibility & Compliance
The GT-6011-B accepts specimens prepared from flat paper or board sheets ≤1.0 mm in thickness—ideal for corrugated medium, test liner, recycled kraft, and bleached sulfate grades. Specimen dimensions adhere strictly to standardized 152 mm × 12.7 mm strips, rolled around the mandrel using a certified ring-forming device (not included). All mechanical and software functions comply with GLP documentation requirements, supporting audit-ready test reports with timestamped operator ID, environmental condition logging (optional hygrometer integration), and electronic signature capability when paired with validated LIMS environments. The instrument meets CE marking directives for machinery safety (2006/42/EC) and electromagnetic compatibility (2014/30/EU).
Software & Data Management
While the GT-6011-B operates autonomously via its embedded microcontroller, optional PC-based software (GOTECH TestSuite v3.2) enables advanced data handling: batch report generation in PDF/Excel formats, statistical process control (SPC) charting (X̄-R, Cp/Cpk), outlier detection via Grubbs’ test, and export of raw force-displacement curves in CSV format. All test files include metadata fields for sample ID, lot number, operator name, calibration certificate ID, and environmental temperature/humidity (if external sensors are connected). Software validation packages—including IQ/OQ documentation, 21 CFR Part 11 compliance modules (electronic signatures, audit trail, role-based access)—are available for regulated pharmaceutical and medical device packaging labs.
Applications
- Quality assurance of incoming linerboard and fluting stock in corrugated converting plants
- Process optimization of wet-end chemistry and drying profiles in paper mills
- Validation of recycled fiber blend performance under varying refining intensity
- Supporting ISTA 3A/3E/6-FE packaging qualification protocols through RCT-to-ECT modeling
- Research into fiber morphology effects on compressive stiffness using controlled pulp refining trials
- Third-party certification testing for FSC®, PEFC™, or SFI™ chain-of-custody claims requiring documented mechanical property verification
FAQ
What standards does the GT-6011-B support out-of-the-box?
ASTM D638, ISO 12192, TAPPI T818, and GB/T 2679.8 — all implemented via preset test profiles with configurable dwell time, speed, and trigger thresholds.
Is calibration traceable to national standards?
Yes. Each unit ships with a factory calibration certificate traceable to CNAS-accredited reference standards; annual recalibration services include NIST-traceable load cell verification.
Can the tester accommodate non-standard specimen widths?
No. To ensure measurement validity, only 12.7 mm wide strips are supported per international standard geometry requirements; deviation invalidates RCT comparability.
Does the system support networked data transfer?
Not natively — it features RS-232 only. Ethernet or Wi-Fi connectivity requires integration via industrial protocol gateways (e.g., Modbus TCP converters) and custom middleware.
What maintenance intervals are recommended?
Lubrication of lead screws and inspection of load cell mounting bolts every 6 months; annual verification of platen parallelism and mandrel concentricity by authorized service engineers.
