ISO 16260

Introducing ISO 16260 – Industrial Physics  

ISO 16260 is a global ISO internal bond strength testing standard that’s used to determine the energy required to rapidly delaminate a test piece of paper or board.  

Internal strength testing – also known as internal bond (Ibond) or scott bond testing – gives you important paper strength information.   

ISO 16260 describes an internal bond strength testing method to measure the energy required to rapidly delaminate a test sample. The rupture of the test piece in this paper strength test is caused by a pendulum with a defined mass that is moving at a defined velocity. 

ISO internal bond strength testing

ISO 16260 testing will determine the internal bond strength of the specimen, offering you important QA information for manufacturers and suppliers on the performance of your paper and board samples under impact. 

The ISO 16260 method is suitable for both single and multi-ply papers and boards, including coated sheets and ones that have been laminated with synthetic polymer films. It’s particularly useful for papers and boards that may be subjected to rapid impacts, impulses, or shock loads in the z-direction during printing or conversion. 

Understanding the ISO 16260 technique

During an ISO 16260 paper strength test your paper and board samples are held static between two double-coated tape substrates. The speed at which this pendulum is able to delaminate the paper or board returns information about the ‘z’ thickness direction of the sample. 

The weight of the pendulum can be changed to suit the sample. Some testing machines also cut down on user effort, with automatic cut and press functions, or give you the ability to test more than one sample at a time. 

The ISO 16260 internal bond strength testing method requires the sample to be adhered to double-sided adhesive tape under pressure, so delicate or porous samples – such as tissue – may not be able to withstand the testing process.

So, how can Industrial Physics improve your ISO 16260 internal bond strength testing?  

Internal Bond Tester 80-26 

The TMI Internal Bond™ Tester is designed to determine the internal bond strength of a variety of paper and board materials according to TAPPI T 569 and ISO 16260 standards.  

It uses a falling pendulum approach, which creates a high speed impact on a paper specimen.  

Internal Bond Sample Prep Station 80-30 

When you need perfect samples for I bond testing, this reliable sample preparation station from TMI provides the solution.

To ensure repeatable and precise paper strength test data it automatically presses and cuts consistently high quality test specimens to exact requirements. It also features touch screen technology and automated test setups.
