Overview
The GOTECH GT-7013-ADP Digital Burst Strength Tester is an electromechanical testing instrument engineered for precise determination of the burst strength of flexible sheet materials—including corrugated board, paperboard, packaging films, nonwovens, and textile laminates. It operates on the principle of hydraulic or pneumatic pressure application (configurable per standard compliance) to a circular test specimen clamped between two annular dies, with rupture force measured via high-resolution digital pressure transduction. The system conforms to core international test standards including ISO 2759, ASTM D774, TAPPI T810, and GB/T 6545—enabling laboratories to generate auditable, repeatable data for quality control, material qualification, and regulatory submissions. Unlike analog dial-based testers, the GT-7013-ADP employs a calibrated load cell or pressure sensor with 0.1 kPa resolution, delivering 100× higher measurement fidelity than legacy pointer-type instruments.
Key Features
- Digital peak-hold function: Automatically captures and retains the maximum burst pressure at specimen failure—eliminating operator interpretation error and ensuring consistent endpoint detection.
- High-resolution transducer system: Integrated pressure sensor with sub-kPa resolution and factory-calibrated traceability to national metrological standards (e.g., CNAS-accredited calibration certificates available).
- Programmable test parameters: Adjustable clamp diameter (standard 31.7 mm per ISO 2759; optional 1.2″ or 1.75″ dies), ramp rate control, and dwell time configuration for method-specific protocols.
- Thermal-stable mechanical frame: Rigid cast-iron base and precision-machined die assembly minimize deflection under load, supporting long-term repeatability (RSD ≤ 1.2% per ASTM D774 repeatability criteria).
- Integrated thermal printer: Direct hardcopy output of test ID, date/time stamp, burst value (kPa or psi), and pass/fail status—supporting GLP documentation requirements without external software dependency.
- Manual and semi-automatic operation modes: Toggle between operator-initiated pressurization and programmable auto-start sequences for integration into production-line QC workflows.
Sample Compatibility & Compliance
The GT-7013-ADP accommodates flat, non-porous, and moderately porous sheet specimens up to 300 g/m² basis weight and 5 mm thickness. Compatible substrates include single- and double-wall corrugated fiberboard, solid bleached sulfate (SBS) board, kraft linerboard, metallized PET films, and coated medical packaging laminates. All test configurations adhere to the dimensional tolerances and clamping force specifications defined in ISO 2759 Annex A and TAPPI T810 Section 6. For regulated environments—such as pharmaceutical primary packaging validation—the instrument supports IQ/OQ documentation packages and meets mechanical accuracy requirements referenced in USP <1207> for container closure integrity assessment methodology.
Software & Data Management
While the GT-7013-ADP functions autonomously with embedded firmware and onboard printing, optional USB-to-PC connectivity enables raw data export in CSV format for post-test analysis in Excel or LIMS platforms. The firmware supports user-defined test profiles (up to 16 saved methods), password-protected parameter locking for SOP enforcement, and audit-trail logging of calibration events and operator logins—aligning with FDA 21 CFR Part 11 principles for electronic records where local validation is performed. Calibration intervals are configurable and logged with timestamped entries, facilitating internal QA audits and ISO/IEC 17025 accreditation readiness.
Applications
- Corrugated packaging R&D: Quantifying edge crush resistance correlation via burst strength–ECT modeling per FEFCO Directive 3.
- Printing & converting quality assurance: Monitoring batch-to-batch consistency of coated board tensile integrity prior to flexographic or gravure printing.
- Medical device packaging validation: Verifying seal burst thresholds of Tyvek®-polyethylene pouches against ISO 11607-1 clause 7.3 requirements.
- Automotive interior materials testing: Evaluating puncture resistance of headliner composites and door panel laminates under simulated impact loading.
- Academic polymer research: Correlating burst modulus with crosslink density in thermoset film formulations.
FAQ
What standards does the GT-7013-ADP comply with?
ISO 2759, ASTM D774, TAPPI T810, DIN 53133, GB/T 6545, and JIS P8135.
Is calibration certification included with shipment?
A factory calibration report with uncertainty values is provided; CNAS-accredited third-party calibration certificates are available upon request.
Can the instrument be integrated into a networked QC lab environment?
Yes—via optional RS-232 or USB interface, enabling automated data capture into LIMS or MES systems using Modbus RTU or ASCII protocol.
What maintenance is required for long-term accuracy?
Annual verification of pressure transducer linearity and die concentricity is recommended; no routine lubrication or consumable parts are required.
Does the tester support dual-unit display (kPa and psi)?
Yes—user-selectable units are configurable in the system menu, with automatic conversion and printed output in the selected unit set.
