Paper ring compression strength tester
A corrugated box compression tester evaluates a carton's ability to withstand vertical loads, simulating stacking pressures during storage or transit. This article outlines key standards, technical specs, operational mechanics, and testing principles to guide users in optimizing packaging design and quality control.
Applicable Standards
The tester adheres to global standards such as ASTM D642 (shipping container compression testing), ISO 12048 (corrugated board flat crush), and GB/T 4857.16 (transport package stacking simulation). Compliance ensures reliable data for regulatory and quality assurance purposes.
Main Parameters
| Parameter | Specifications |
|---|---|
| Max. Compression Force | 5-50 kN (adjustable) |
| Test Plate Dimensions | Customizable (e.g., 1200×800 mm) |
| Compression Speed | 10-300 mm/min (programmable) |
| Force Accuracy | ±0.5% FS |
| Safety Features | Emergency stop, overload protection |
Working Principle
Powered by hydraulic or electric actuators, the machine applies controlled downward force on a carton. Sensors track deformation and peak load at failure, while software generates reports on compressive strength, energy absorption, and structural integrity.
Test Principle
Replicating real-world stacking scenarios, the test determines a carton's maximum load capacity before collapse. Data supports material selection, design improvements, and compliance with shipping standards.
This concise guide equips industries to enhance packaging resilience, reduce damages, and ensure regulatory adherence through precise compression testing.
