This test evaluates the ability of a terminated wire sample to maintain its structural integrity under conditions of repeated stress at the point of termination. The location of a crimp termination on a wire is more likely to experience conditions of mechanical stress than other locations along the length of the wire. It is crucial in the design of any electrical system for terminations on wires to be physically dependable, particularly in aerospace applications where regular maintenance and movement-related stresses are common.
Performance is carried out much like that of other flex life testing but with the stress applied to the location of the crimp termination
