What is ISO 23817:2018?

ISO 23817:2018, titled "Paper and board - Determination of the bending stiffness - General principles", is a standard established by the International Organization for Standardization (ISO). This standard provides guidelines for testing the bending stiffness of paper and board materials. In this article, we will explore the key concepts of ISO 23817:2018 in a simplified manner for better understanding.

The importance of bending stiffness

Bending stiffness refers to the resistance of paper or board to bending. It is an important property that determines the performance of various products such as packaging materials, cardboard boxes, and even books. High bending stiffness ensures structural integrity, prevents deformation and improves the overall quality of paper-based products. ISO 23817:2018 sets out standardized methods to measure bending stiffness, allowing manufacturers to meet quality assurance requirements and ensure consistent product performance.

Principles of ISO 23817:2018

ISO 23817:2018 outlines the general principles for determining the bending stiffness of paper and board. The standard defines the test conditions, apparatus, sample preparation, and calculation methods to be followed during testing. These guidelines ensure accuracy, reliability, and comparability of test results across different laboratories and manufacturers. By adhering to these principles, manufacturers can evaluate and improve the bending stiffness of their paper and board products, meeting customer expectations and regulatory requirements.

Benefits and applications of ISO 23817:2018

ISO 23817:2018 provides numerous benefits to both manufacturers and consumers. For manufacturers, adherence to this standard allows them to assess the quality of their materials, make informed design choices, and enhance product performance. Consistent testing methods enable easy comparison of different paper and board products, facilitating market competitiveness. Consumers, on the other hand, benefit from improved product durability, reduced risk of damage during handling and transportation, and enhanced overall user experience. Additionally, compliance with this international standard strengthens trust and confidence in the industry.
