Automatic Box Burst Strength Tester

Overview

The Automatic Box Burst Strength Tester is a dedicated mechanical testing instrument engineered for the quantitative evaluation of corrugated fiberboard and packaging carton integrity under controlled hydraulic pressure. It operates on the principle of the Mullen burst test—applying uniformly increasing hydraulic pressure to a fixed area of specimen until rupture occurs—thereby measuring the maximum resistance (burst strength) in kg/cm², newtons (N), or pounds-force (lbf). Designed in strict accordance with ISO 7267-1 (“Paper and board — Determination of bursting strength — Part 1: Hydraulic method”) and ASTM D774 (“Standard Test Method for Bursting Strength of Paper and Paperboard”), this tester delivers repeatable, metrologically traceable results essential for quality assurance in packaging R&D, production line QC, and third-party certification laboratories. Its closed-loop hydraulic actuation system, coupled with real-time digital transduction, ensures minimal hysteresis and high reproducibility across sequential tests.

Key Features

• High-accuracy hydraulic pressure transducer calibrated to ±1 kPa uncertainty, enabling precise determination of burst point with 0.1 kg/cm² resolution.
• Robust construction featuring a brass alloy hydraulic cylinder, precision-ground stainless steel test head, and anodized aluminum front panel—optimized for long-term stability and resistance to environmental wear.
• Integrated microprocessor control system with real-time display of clamping force and burst pressure; supports automatic cycle initiation, peak-hold capture, and immediate result output.
• High-speed thermal printer (non-impact, low-maintenance) for on-demand hardcopy generation of test reports—including date/time stamp, sample ID, measured value, and unit selection.
• Onboard calibration mode accessible via password-protected menu, allowing accredited metrology labs to perform full-range verification and adjustment without disassembly or external hardware.

Sample Compatibility & Compliance

The tester accommodates standard 100 mm × 100 mm (or 150 mm × 150 mm with optional adapter) specimens of single-, double-, or triple-wall corrugated board, solid fiberboard, and laminated paperboard. Clamping force is pneumatically stabilized to eliminate edge deformation artifacts during pressurization. All mechanical and electronic components conform to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. The device meets the essential requirements of the EU Machinery Directive 2006/42/EC and carries CE marking. Calibration documentation supports compliance with ISO/IEC 17025-accredited testing environments and satisfies audit requirements for GLP, GMP, and FDA 21 CFR Part 11–aligned data integrity protocols when paired with validated software logging.

Software & Data Management

While the base configuration operates as a standalone instrument with local LED display and thermal printout, optional RS-232 or USB-C serial interface enables integration with laboratory information management systems (LIMS) or custom QA databases. A companion Windows-based utility (PL-100 DataLink v2.1) provides CSV export, statistical analysis (mean, SD, CV%), batch reporting, and time-stamped audit logs with user authentication. All stored test records include operator ID, environmental conditions (optional external hygrometer input), and calibration status flags—supporting full traceability per ISO 9001:2015 clause 8.5.2 and ASTM E2500-13 Annex A2.

Applications

This instrument is routinely deployed in packaging material supplier QA labs, e-commerce fulfillment center process validation, food & pharmaceutical secondary packaging qualification, and regulatory submission support for ISTA 3A/6AM-compliant shipping container testing. It serves as a critical benchmark for correlating burst strength with edge crush test (ECT) values, predicting stacking performance, and verifying compliance with TAPPI T 403 om-19, ISO 12192, and GB/T 6545–1998. In academic settings, it supports research into fiber orientation effects, moisture-dependent strength degradation, and recycled content impact on structural resilience.

FAQ
