Summary of ISO 2759 Bursting Strength Testing of Boards
ISO 2759 defines a standardized test method for evaluating how paper and board respond to wet compressive stress. In this test, controlled water exposure applies to the material. As a result, the method measures key mechanical properties under wet conditions. These results help determine strength, durability, and resistance to water damage.
In packaging applications, ISO 2759 plays a critical role in package integrity testing. It evaluates how paper and board materials perform within a full packaging system. Because of this, manufacturers and distributors use the standard to verify material quality and consistency. In turn, it helps ensure products ship safely and securely.
When companies perform package integrity testing, they reduce the risk of transit damage. This also improves overall reliability throughout the supply chain. Ultimately, it supports better customer satisfaction and fewer product failures.
Additionally, ISO 2759 delivers a repeatable and standardized method for assessing wet strength properties. Therefore, it serves as an important tool for quality control and product development across the paper and packaging industry.
ISO 2759 Package Testing Procedures
The ISO 2759 package test procedure begins by placing a specimen in a water bath. Next, the system applies a controlled compressive load, typically measured in kilopascals (kPa). As the load increases, the test captures peak compressive stress, time to peak stress, and material deformation under load.
To accommodate different material behaviors, ISO 2759 defines three test methods. Method A applies to rigid materials that resist deformation, such as high-strength corrugated board. In contrast, Method B evaluates highly deformable materials like lightweight tissue paper. Meanwhile, Method C is used for materials with moderate deformation, including medium-weight packaging paper.
During testing, the apparatus applies load gradually to the wetted specimen. As a result, the material response is recorded over time. This includes how the structure deforms as stress increases under wet conditions.
Finally, the test results provide key performance indicators such as peak compressive stress, time to maximum stress, and total deformation. Together, these values help evaluate wet strength performance. For example, they indicate resistance to wet buckling, shape retention under load, and durability against tearing or breakage when saturated.
