For reliable and repeatable test purposes, the system would need to perform routine batch sample evaluations. The company estimated that loads would measure in the region of up to 20kN, enabling a semi-automatic test to be performed. Mecmesin provided a twin-column test system capable of measuring forces up to 25kN. A bespoke fixture was designed to offer a suitable method of performing heavy-duty pull-off tests, which gave the best possible accuracy.
