The testing protocol had four stages: preloading, cyclic preconditioning, incremental cyclic loading and pull-to-failure. A 20 N preload was first applied, followed by 10 preconditioning cycles at 1 Hz with loads between 20 and 70 N, incremental loading involved 5000 cycles at 1 Hz with loads between 20 and 520 N, lastly a test to failure was performed at a rate of 20 mm/min
