PUNCTURE TESTING - a new approach
The traditional falling dart method for testing the impact strength of thin materials has always been problematic and many users have questioned the acurracy of the interpretation of the failure mode by the operater.
The pendulum puncture tester has found a place in the market because the benifts it brings in testing thin materials is unquestionably much better.
By using a pendulum system, the energy to puncture a test sample is obtained in the same way as performing an izod or charpy test. Therefore, there is no need to carry out a statistical analysis to obtain a result.
The above pictures show typical puncture examples.
The appartaus is "self calibrating" every time it is used.
