Buchel BV 13-6X Bursting Strength Tester

Overview

The Buchel BV 13-6X Bursting Strength Tester is a precision-engineered instrument designed for the quantitative evaluation of bursting resistance in corrugated fiberboard, paperboard, packaging films, and laminated substrates. It operates on the fundamental principle of hydraulic (or pneumatic-hydraulic) pressure application via an elastomeric diaphragm, which exerts uniform, radially symmetric force against a clamped specimen until rupture occurs. The resulting peak pressure—expressed in bar—is directly correlated to the material’s structural integrity under multidirectional stress, making it a critical parameter in packaging qualification per ISO 2759, ASTM D774, TAPPI T810, and FEFCO No. 5. Unlike tensile or puncture testers, the 13-6X replicates real-world conditions where packaging is subjected to internal pressure buildup (e.g., during stacking, vacuum sealing, or thermal expansion), thereby delivering physiologically relevant failure metrics.

Key Features

• High-fidelity pressure measurement system featuring a factory-calibrated, temperature-compensated strain-gauge sensor with a full-scale range of 0–100 bar
• Measurement accuracy compliant with ISO 2759:2022 requirements: ±1% of reading or ±0.1 bar, whichever is greater—ensuring traceability to national metrological standards
• 2 mbar resolution (50,000 discrete data points across full scale), enabling detection of subtle pre-failure behavior and consistent inter-laboratory repeatability
• Robust dual-clamp mechanism with pneumatically assisted loading ensures uniform specimen fixation without edge deformation or slippage
• Integrated diaphragm life counter logs cumulative test cycles to support preventive maintenance scheduling and GLP-compliant equipment usage records
• Modular design accommodates optional accessories including humidity-controlled test chambers and specimen alignment jigs for low-basis-weight materials

Sample Compatibility & Compliance

The 13-6X accepts standard circular specimens (100 mm diameter per ISO 2759; 150 mm per FEFCO specifications) cut from flat sheets or converted packaging. It supports both single- and multi-ply structures—including wax-coated board, metallized films, and bio-based laminates—provided surface roughness does not exceed Ra ≤ 15 µm to ensure diaphragm seal integrity. All mechanical and electronic subsystems conform to CE marking requirements under the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. Calibration procedures align with ISO/IEC 17025:2017 clause 6.5, and documented uncertainty budgets are available upon request for audit readiness.

Software & Data Management

The optional TMI GraphMaster™ software provides a validated interface for Windows-based PCs, supporting FDA 21 CFR Part 11 compliance through user-level access control, electronic signatures, and immutable audit trails. It enables automated test sequencing (e.g., ramp rate definition, dwell time, burst threshold triggering), real-time curve visualization (pressure vs. time), and export of raw datasets in CSV or ASTM E1447-compliant XML format. Calibration coefficients, operator IDs, environmental metadata (ambient temperature/humidity), and diaphragm usage logs are embedded within each test file—facilitating full traceability in GMP-regulated environments such as pharmaceutical secondary packaging validation.

Applications

• Quality assurance of shipping containers and retail-ready packaging prior to distribution
• Supplier qualification testing for inbound corrugated board and recycled fiberboard
• R&D evaluation of barrier film composites under simulated transit conditions
• Correlation studies between bursting strength and compression performance (e.g., edge crush test,ECT)
• Regulatory submission support for ISTA 3A/3E-compliant packaging dossiers
• Root cause analysis of field failures involving bulging, seam splitting, or liner delamination

FAQ

What standards does the 13-6X support out-of-the-box?
It natively complies with ISO 2759, ASTM D774, TAPPI T810, and FEFCO No. 5 test methodologies. Custom protocol templates can be configured for JIS Z1516 or GB/T 6545 via GraphMaster™.
Is third-party calibration certification included?
Factory calibration is performed using NIST-traceable deadweight testers; ISO/IEC 17025-accredited calibration certificates are available as a chargeable service.
Can the instrument be integrated into a LIMS environment?
Yes—GraphMaster™ supports ODBC connectivity and structured data export, enabling direct ingestion into laboratory information management systems meeting ISO 15197 or CLIA requirements.
What maintenance intervals are recommended for the diaphragm?
Based on typical usage (≤200 tests/week), replacement is advised every 12 months or after 10,000 cycles—whichever occurs first—to maintain pressure linearity and seal integrity.
Does the system require compressed air or external hydraulics?
No—the 13-6X uses an integrated electro-hydraulic actuation system; only standard 100–240 VAC power input is required.
