PUNCTURE IMPACT TESTING
A different approach to the falling weight method. No need for operators to interpret the mode of failure and carry out a statistical analysis to obtain the test result.
The new impact puncture method is based on the pendulum impact system commonly used for Izod and Charpy impact tests which has proven to be very reliable for many years now and takes full advantage of a microprocessor controlled system.
The tup profiles can quickly be changed which makes it ideal for evaluating packaging materials, especially as in most cases the tup can represent the components that are to be packaged in the material.
The test sample takes a circular form so that the orientation of the material relative to the manufacturing processes is not effected
