What is EN ISO 13867-2021?

EN ISO 13867-2021 is an international technical standard that provides guidelines for measuring the bursting resistance of paper and board. This standard specifies a method called the "ball burst test" which measures the ability of a material to withstand puncture or rupture when subjected to a high-pressure load. The standard was developed by the International Organization for Standardization (ISO) in collaboration with the European Committee for Standardization (CEN) to establish a uniform testing procedure and ensure quality consistency in the paper and board industry.

The Importance of EN ISO 13867-2021

EN ISO 13867-2021 plays a crucial role in various industries where paper and board are used. By providing a standardized testing method, this standard allows manufacturers, suppliers, and buyers to assess the quality and performance of different materials accurately. It helps ensure that paper and board products meet specific requirements for strength and durability. Compliance with EN ISO 13867-2021 also enables fair competition and enhances customer confidence, as it guarantees that products have been evaluated using an objective and reliable measurement system.

The Ball Burst Test Procedure

The ball burst test, as outlined in EN ISO 13867-2021, involves applying a gradually increasing pressure to a specimen until it ruptures. A spherical-shaped plunger with a specified diameter is pressed against the sample, creating a localized stress point. The pressure is then increased until the material bursts. The burst strength is measured in kilopascals (kPa), representing the pressure required to break the specimen. The test results provide valuable information about the material's resistance to puncture, helping manufacturers select suitable materials for various applications, such as packaging, bookbinding, and printing.

Implementing EN ISO 13867-2021

To implement EN ISO 13867-2021, manufacturers and testing laboratories need to ensure proper equipment calibration and follow the standard's guidelines precisely. The testing procedure should be performed by trained technicians in controlled conditions to minimize external factors that may affect the results. Regular quality control measures, including inter-laboratory comparisons, are necessary to maintain the reliability and consistency of test outcomes. Compliance with this standard not only enhances product quality but also promotes international trade, as it facilitates harmonization of testing practices among different countries.
