Characterisation of tape performances is much more difficult compared to measuring the length of a screw, e.g. several factors have a significant influence on the final properties of tapes. This session will cover the most important test methods, presenting globally harmonised GTF standards as well as tests that are used on a more international level like Afera, PSTC and JATMA. Dos and don´ts will be discussed and several real-life examples of tape tests from different industries will be presented. After this lesson, you should have a better understanding of the potentials and the limits of tape testing – and hopefully you will use your thumb less often.
