Drick DRK109BQ Pneumatic Bursting Strength Tester with Keypad Interface and Automated Measurement

Overview

The Drick DRK109BQ is a fully pneumatic, microprocessor-controlled bursting strength tester engineered for high-precision evaluation of the rupture resistance of paper, cardboard, corrugated board, and other fibrous packaging materials. It operates on the principle of hydraulic (pneumatic-hydraulic hybrid) pressure application via a diaphragm-driven rubber membrane, conforming to the fundamental mechanics defined in ISO 2758, ISO 2759, TAPPI T403, and GB/T 454—standards governing bursting strength measurement across global packaging quality laboratories. Unlike manual or semi-automatic variants, the DRK109BQ integrates real-time pressure transduction, closed-loop pneumatic actuation, and embedded intelligent algorithms that automatically detect peak burst pressure, compensate for membrane expansion error, and compute normalized bursting strength (kPa) and bursting index (kPa·m²/g) without operator intervention. Its robust cast-aluminum frame, sealed pneumatic circuitry, and temperature-stable load cell ensure long-term repeatability (< ±1.0% RSD per ASTM D7269) under routine QC conditions.

Key Features

• Pneumatic actuation system with digitally regulated air supply (0–1.2 MPa range), eliminating oil contamination and mechanical hysteresis associated with hydraulic pistons
• Integrated keypad interface with backlit LCD display for standalone operation—no PC required for routine testing
• Auto-zero calibration and dynamic pressure compensation for membrane deformation, compliant with ISO 2758 Annex B correction methodology
• Programmable pre-load function (0.5–2.0 kPa) to stabilize sample prior to ramped pressurization, minimizing edge effects and improving inter-laboratory reproducibility
• Real-time pressure curve logging (100 Hz sampling rate) with on-device storage for ≥500 test records, exportable via USB 2.0 port
• Compliance-ready audit trail: timestamped test logs include operator ID, sample ID, environmental temperature/humidity (optional sensor input), and pass/fail status against preset limits

Sample Compatibility & Compliance

The DRK109BQ accommodates standard circular specimens of 31.5 mm diameter (ISO-compliant clamping area), with optional adapters available for 15.9 mm (TAPPI) and 100 mm (custom heavy-duty board) configurations. It supports grammage ranges from 40 g/m² (tissue) to 600 g/m² (double-wall corrugated board), and thicknesses up to 8.0 mm. All mechanical and pneumatic components meet IP54 ingress protection standards for dust and splash resistance in production-floor environments. The instrument’s firmware and data handling architecture support GLP/GMP-aligned workflows, including electronic signatures (via optional USB keyboard), 21 CFR Part 11–compatible user access levels (admin/operator/auditor), and traceable calibration certificate management through Drick’s Calibration Management Module (CMM v3.2).

Software & Data Management

While fully functional as a stand-alone tester, the DRK109BQ is compatible with DrickLab™ Suite v5.1—a Windows-based laboratory software platform supporting automated report generation (PDF/Excel), statistical process control (SPC) charting (X̄-R, Cp/Cpk), and integration into LIMS via ASTM E1384-compliant HL7 messaging or ODBC database export. Raw pressure-time datasets are stored in IEEE 754-compliant binary format (.drkbin), ensuring bit-level fidelity for third-party reanalysis. All exported reports embed digital watermarks, cryptographic hash signatures, and full metadata (including firmware revision, sensor serial numbers, and calibration expiration dates) to satisfy regulatory audit requirements.

Applications

• Quality assurance of linerboard, kraft paper, and recycled fiberboard in packaging manufacturing plants
• R&D validation of wet-strength additives, sizing agents, and nanocellulose reinforcement in pulp & paper labs
• Supplier qualification testing per ISTA 3A/6A protocols for e-commerce shipping containers
• Regulatory submission support for FDA 21 CFR 176.170-compliant food-contact paper products
• Correlation studies between bursting strength, tensile strength (ISO 1924), and tear resistance (ISO 1974) for predictive modeling

FAQ

Does the DRK109BQ require annual recalibration?
Yes—certified recalibration is recommended every 12 months or after 5,000 test cycles, using NIST-traceable pressure standards and documented in accordance with ISO/IEC 17025.

Can it measure bursting strength of coated or laminated papers?
Yes, provided the coating remains adhered during pressurization; delamination-induced premature failure must be flagged manually in the test log per ISO 2758 Clause 8.3.

Is the pneumatic system compatible with nitrogen purge for inert-atmosphere testing?
Yes—the unit accepts regulated dry nitrogen (dew point ≤ −40°C) as an alternative to compressed air; no hardware modification is required.

What is the maximum allowable ambient temperature for continuous operation?
40°C ambient, with relative humidity ≤ 80% non-condensing; extended operation above 35°C requires active ventilation per IEC 61000-6-2 EMC guidelines.

Does Drick provide IQ/OQ documentation packages for pharmaceutical clients?
Yes—validated installation qualification (IQ) and operational qualification (OQ) protocols, executed by certified field service engineers, are available as optional deliverables aligned with Annex 15 and USP .
