Abstract
A method and an apparatus for determining the eventual elongation property of a copper wire which has been cold drawn with an intermediate anneal and which is to be subsequently subjected to a predetermined heat treatment by a final in-line continuous anneal. Before a sample length of such wire is elongated to its breaking point in a tensile testing device, a capacitor is discharged through the wire length to produce a heating current flow therethrough of a magnitude and duration that produces a heat treatment of the wire length which approximately simulates that which would be the result of the final in-line continuous anneal. For this purpose, the wire holding devices of the tensile testing device have contact means to establish connection of the wire length in a discharge circuit for the capacitor.
