Drick DRK109 Pneumatic Bursting Strength Tester for Single- and Multi-Wall Corrugated Board

Overview

The Drick DRK109 Pneumatic Bursting Strength Tester is a precision-engineered instrument designed for the quantitative determination of bursting strength in paper, paperboard, and corrugated fiberboard—specifically engineered to meet international standard requirements for packaging material integrity assessment. It operates on the principle of hydraulic pressure application through a flexible diaphragm (rubber or elastomeric membrane), which exerts uniform radial force against a clamped specimen until rupture occurs. The resulting peak pressure—recorded in kilopascals (kPa)—serves as the fundamental metric for material resistance to localized puncture and internal stress under controlled deformation. This method is universally recognized for its reproducibility in evaluating structural robustness across single-ply papers, duplex boards, and multi-layer corrugated configurations (e.g., single-wall, double-wall, and triple-wall board). The DRK109 conforms strictly to ISO 2759 (Paperboard — Determination of bursting strength), GB/T 6545 (Corrugated fiberboard — Determination of bursting strength), GB/T 454 (Paper — Determination of bursting strength), QB/T 1057 (Bursting strength testers for paper and paperboard), and GB 1539 (Paperboard — Method for determination of bursting strength), ensuring metrological traceability and regulatory alignment for quality control laboratories in packaging manufacturing, third-party testing facilities, and R&D departments.

Key Features

• Integrated 7-inch capacitive touchscreen interface with intuitive navigation, enabling fully automated test sequencing—including specimen loading confirmation, pressure ramp initiation, burst detection, and result finalization—without manual intervention.
• Self-developed firmware with real-time pressure calibration, intelligent burst-point recognition algorithm, and dynamic compensation for diaphragm elastic hysteresis, minimizing measurement drift across extended operational cycles.
• High-fidelity hydraulic actuation system featuring a dual-seal copper-steel cylinder assembly with four-stage sealing architecture, rated for sustained operation up to 6000 kPa without leakage—validated per ISO 2759 Annex B for long-term pressure retention stability.
• Motor-driven clamping mechanism with programmable pre-load activation ensures consistent specimen fixation at >690 kPa, eliminating variability from manual torque application and reducing operator-induced error.
• Onboard non-volatile memory capable of storing up to 500 test batches (20 specimens per batch), totaling 10,000 individual data records with timestamp, operator ID, environmental metadata (optional via external sensor integration), and raw pressure-time curve export capability.
• Integrated thermal line printer with jam-resistant paper feed, supporting immediate hardcopy output of test reports compliant with GLP documentation standards—including header fields for sample ID, test date, standard reference, and pass/fail flag based on user-defined thresholds.

Sample Compatibility & Compliance

The DRK109 accommodates flat, non-curling specimens of paper, solid bleached sulfate (SBS) board, recycled fiberboard, and all standard corrugated configurations (A-, B-, C-, E-, F-flute and combinations thereof), provided specimen dimensions meet minimum 150 mm × 150 mm and thickness ≤ 8 mm. While optimized for fibrous substrates, it is also validated for use with woven textiles including silk and cotton fabric per ASTM D3786 (Bursting Strength of Textiles—Diaphragm Method), subject to adapter ring modification and procedural adaptation. All mechanical and software functions comply with ISO/IEC 17025:2017 clause 6.4 (Equipment) and support audit readiness for FDA 21 CFR Part 11 (electronic records/electronic signatures) when deployed with optional networked validation packages. Calibration certificates are issued traceable to NIM (National Institute of Metrology, China) or equivalent national metrology institutes.

Software & Data Management

Firmware v3.2 includes embedded database architecture supporting CSV and XML export via USB host port, compatible with LIMS integration protocols (HL7, ASTM E1384). Audit trails log all parameter modifications, calibration events, and user login sessions with immutable timestamps. Optional PC-based analysis suite (DRK-BurstSuite Pro) enables statistical process control (SPC) charting—X̄-R charts, Cp/Cpk calculation, outlier detection via Grubbs’ test—and comparative cohort analysis across material grades, production lots, or supplier batches. Data encryption (AES-128) and role-based access control (RBAC) align with ISO 27001 information security frameworks.

Applications

• Quality assurance of linerboard and medium in corrugated box manufacturing lines.
• Validation of recycled content impact on board burst resistance during sustainability certification audits (e.g., FSC, PEFC).
• Comparative evaluation of starch-based vs. synthetic adhesive systems in flute bonding integrity studies.
• Pre-shipment testing of export-grade packaging per ISTA 3A/6E protocols requiring burst strength verification.
• Research into nanocellulose-reinforced paper composites where localized failure mechanics differ significantly from conventional pulp matrices.
• Regulatory submission support for medical device packaging per ISO 11607-1, where burst resistance correlates with sterile barrier integrity.

FAQ

What standards does the DRK109 directly support out-of-the-box?
The instrument is factory-configured to execute ISO 2759, GB/T 6545, GB/T 454, QB/T 1057, and GB 1539 test routines with preloaded pressure ramp profiles and acceptance criteria.
Is external air supply mandatory for operation?
Yes—the unit requires a clean, dry compressed air source at 0.7 MPa (100 psi) delivered via Ø8 mm polyurethane tubing; an integrated oil-free air compressor module is available as an accessory option.
Can test data be exported to Excel or LIMS without proprietary software?
Yes—raw .csv files containing full pressure-time series, burst value, time-to-failure, and environmental metadata are exportable via USB flash drive in plain-text format.
How often does the rubber diaphragm require replacement?
Under typical QC lab usage (≤20 tests/day), the diaphragm maintains metrological validity for ≥12 months or 5,000 cycles, verified by daily zero-pressure check and monthly calibration using NIST-traceable deadweight tester.
Does the DRK109 support GLP-compliant electronic signatures?
When paired with optional DRK-AuthServer license, it implements 21 CFR Part 11-compliant digital signature workflows with biometric authentication logging and sealed audit trail archiving.
