Introducing ISO 1924 - Industrial Physics  

ISO 1924 is a set of international ISO standard procedures that are designed to determine the tensile strength, strain at break and tensile energy absorption of paper and board. 

This ISO tensile test is applicable to most papers and boards. Even those that have a high strain at break…assuming the results are within the capacity of the tensile testing machine. It also works with the components of corrugated board - but not the corrugated board final product itself. 

What is tensile testing? 

Tensile strength testing involves pulling a sample apart until it fails and then measuring the amount of effort involved. The measured figure is known as the tensile strength of the sample. It’s a broad term that refers to all types of force and materials strength testing applications that follow this process. 

Performing tensile testing of your paper and board samples to ISO 1924 standards is an important check. Accurate paper and board tensile testing enables you to understand the integrity of your materials and how they will perform in the real world.  

To determine the tensile properties of your materials - including the tensile strength, strain at break and tensile energy absorption, you’ll need a robust and accurate tensile tester.  

Another helpful aspect of ISO 1924 testing is that it specifies equations for calculating the tensile index, the tensile energy absorption index and the modulus of elasticity of your samples.

ISO 1924 testing devices

So, how can Industrial Physics take the tension out of your ISO 1924 tensile testing?  

Horizontal tensile tester 84-56 

Our 84-56 horizontal tensile tester is just what you need for ISO 1924 testing. It’s sensitive and precise enough to inspect tissue, but strong enough to measure packaging boards too. 

It combines a modern contemporary look with a robust mechanical design and new improved electronics. This includes a color touch screen and user-friendly interface. The menus are interactive and the large buttons are designed for easy access. 

Table model universal testing machines 

Our convenient table model frames are surprisingly powerful - generating force from 5 kN up to 100 kN. 

These universal testing machines are ideal for many material types and they’re just what you need for paper and board tensile testing. We can even create bespoke instruments to suit the needs of your operation...just ask!
