ISO 9290 is a standardized test method used to determine the tearing strength of paper and board. The method involves cutting a sample into a specified shape, making a slit in the sample, and then using a pendulum-type tearing tester to tear the sample along the slit. The force required to tear the sample is measured, and this value is used to calculate the tearing strength of the material.

The test method specifies the conditions for testing, including the size and shape of the sample, the orientation of the sample, and the speed of the pendulum. It also provides guidelines for the calculation and expression of results.

ISO 9290 is widely used in the paper and board industry to ensure product quality and consistency. It is an internationally recognized standard that helps to ensure that tearing strength measurements are accurate and comparable across different laboratories and testing facilities.

NextGen’s NG-HE Elmendorf complies with ISO 9290 standard.
