ISO 527-3

Introducing ISO 527-3 – Industrial Physics

ISO 527-3 is an international ISO standard that’s used to determine the tensile properties of plastic films that are less than one millimeter thick.

The ISO 527-3 tensile test will reveal various characteristics of the plastic films you are investigating, such such as: 

• Yield stress 
• Yield strain 
• Maximum stress 
• Nominal strain at break 

ISO 527-3 testing basics  

Through the ISO 527-3 tensile testing method you typically test strips or dumbbell samples which can easily be produced using a specimen or film cutter.  

The results of ISO plastic strip testing and the strain required to break the sample depends on the specimen shape and the type of specimen gripping used. This is perhaps best achieved using parallel clamping specimen grips with the grip inserts arranged for linear contact between the jaw and the specimen. 

Just a little note: the ISO 527-3 method is not suitable for tensile testing of cellular materials or plastics reinforced by textile fibers. 

ISO 527-3 testing devices  

So, how can Industrial Physics improve your ISO 527-3 testing? 

United Testing Universal Testing Machine (UTM) 

Our industry-leading UTMs are just the job for ISO 527-3 plastic strip testing. They give you unparalleled control over your tension testing, compression and bend/flex testing on a variety of parts, components and test samples.  

These popular, software-controlled devices come in a variety of models – from our 5 kN (550 lbf) table model system, up to our 2,000 kN (450,000 lbf) servo-hydraulic system. We will help you to meet and exceed international ISO standard requirements for a wide range of products and test scenarios.  

You could say we’re the best – for your tensile test. But we’d be far too modest to suggest as such!
