Why Bending Stiffness Matters
Bending stiffness is a critical property of paper and board materials, influencing their performance in various applications. Whether you're involved in packaging, printing, or any other industry that relies on paper and board, understanding and controlling bending stiffness is essential. This property affects how materials handle, fold, and resist deformation, impacting everything from the structural integrity of packaging to the quality of printed materials.
Comprehensive Testing Methods
The BS ISO 5628:2019 standard outlines three primary methods for determining bending stiffness:
- Two-Point Method: This method involves supporting the sample at two points and applying a load at the midpoint. It's a straightforward approach that provides quick and reliable results.
- Three-Point Method: In this method, the sample is supported at two outer points, with a load applied at a central point. This technique is particularly useful for assessing the stiffness of thicker materials.
- Four-Point Method: This advanced method involves supporting the sample at two outer points and applying two loads at equal distances from the center. It offers a more uniform stress distribution, making it ideal for precise measurements.
Benefits of Using BS ISO 5628:2019
By adhering to the BS ISO 5628:2019 standard, you ensure that your measurements of bending stiffness are consistent, accurate, and comparable across different tests and materials. This consistency is vital for quality control, product development, and research purposes. Additionally, using a recognized standard like BS ISO 5628:2019 enhances the credibility of your results, making them more acceptable to clients, partners, and regulatory bodies.
Who Should Use This Standard?
The BS ISO 5628:2019 is indispensable for:
- Quality Control Professionals: Ensure that your products meet the required specifications and maintain high standards of quality.
- Research and Development Teams: Develop new products and improve existing ones by understanding the mechanical properties of your materials.

BS ISO 5628:2019
This standard BS ISO 5628:2019 Paper and board. Determination of bending stiffness. General principles for two-point, three-point and four-point methods is classified in these ICS categories:
- 85.060 Paper and board
This document specifies three test methods for determining the bending stiffness of paper and paperboard. The test methods differ in the type of loading mode, thus giving rise to the two-point, three-point and four-point bending test methods.
For paper and paperboard in a low thickness range, the two-point bending method and the three-point bending method are suitable.
For corrugated fibreboard and board with a higher thickness, the four-point bending method is recommended.
The measurement conditions are defined in such a way that the test piece is not subjected to any significant permanent deformation during the test, nor is the range of validity of the formulae for calculating the bending stiffness exceeded.
In these bending tests, the test pieces of paper and board are regarded as “beams” as defined by the science of the strength of materials, see Reference [2].
