Overview
The OKE Universal Bursting Strength Tester is a precision-engineered hydraulic testing instrument designed to determine the bursting strength of corrugated fiberboard, solid fiberboard, paperboard, and other flexible sheet materials used in packaging applications. It operates on the principle of controlled hydraulic pressure application via a rubber diaphragm, which uniformly deforms the test specimen until rupture occurs—measuring the maximum pressure resistance (in kPa or psi) prior to failure. This method conforms strictly to internationally recognized standards including ISO 2759, ASTM D2210, TAPPI T403, and GB/T 6545, ensuring data traceability and regulatory acceptability across global supply chains. The instrument integrates a robust mechanical frame, high-stability pressure transduction system, and programmable clamping force control to deliver repeatable, operator-independent results essential for QC laboratories, packaging R&D centers, and third-party certification bodies.
Key Features
- Automated pneumatic diaphragm pressure actuation with real-time digital pressure feedback and closed-loop regulation
- Standardized 63.5 mm diameter clamping area compliant with ISO 2759 and TAPPI T403 geometrical requirements
- Dual-range pressure sensor (0–1000 kPa / 0–6000 kPa) selectable via software interface for extended dynamic range
- Integrated microprocessor-based controller with LCD display, unit conversion (kPa/psi/kgf/cm²), and zero-point auto-calibration
- Self-diagnostic system monitoring hydraulic seal integrity, diaphragm deformation linearity, and pressure drift
- Modular design supporting optional accessories: temperature/humidity chamber integration, multi-specimen auto-feeder, and GLP-compliant audit trail module
Sample Compatibility & Compliance
The tester accommodates flat, non-porous sheet specimens up to 300 mm × 300 mm in dimension and thicknesses ranging from 0.1 mm to 8 mm—including single- and multi-wall corrugated board, chipboard, kraft linerboard, coated paperboard, synthetic leather, woven/nonwoven textiles, and laminated composites. All measurements adhere to standardized conditioning protocols per ISO 187 (23°C ±1°C, 50% RH ±2%) prior to testing. Full compliance documentation—including Declaration of Conformity, calibration certificate traceable to NIM (China National Institute of Metrology), and test report templates aligned with ASTM E29 and ISO/IEC 17025 reporting guidelines—is supplied with each unit. Instrument validation supports IQ/OQ protocols required under GMP environments for medical device packaging qualification.
Software & Data Management
The embedded firmware supports USB export of raw burst pressure values, time-to-failure curves, and statistical summaries (mean, SD, CV%, min/max) in CSV format. Optional PC-based software (OKE-BurstSuite v3.2) enables advanced data management: automated report generation compliant with FDA 21 CFR Part 11 (electronic signatures, audit trail, user access levels), SPC charting (X-bar/R, Cpk/Ppk), and batch-level trend analysis across multiple instruments. Data encryption, role-based permissions, and secure cloud backup are configurable for enterprise deployment. All software modules undergo annual verification against NIST-traceable reference standards.
Applications
This instrument serves as a core tool in packaging integrity assurance workflows across industries: evaluating compression resistance of e-commerce shipping containers; validating shelf-life performance of food-grade cartons under humidity cycling; verifying structural durability of automotive component packaging; assessing material substitution feasibility in sustainable packaging initiatives; and supporting ISO 9001/14001 internal audits through documented measurement uncertainty budgets. It is routinely deployed in R&D labs at Tier-1 automotive suppliers, pharmaceutical secondary packaging facilities, electronics OEMs, and national metrology institutes conducting interlaboratory comparison studies.
