- 1 This Technical Report gives a method to be used in carrying out the spiral elongation test on copper that has been worked into the form described in clauses 3 and 4. NOTE — The word "spiral" as used in this context implies "helical" in strictly scientific terms. 2 The response of a given copper to the test is influenced by the treatment it has received in the preparation of the wire sample, and for this reason the details of processing are specified. 3 The test applies only to high conductivity copper, sampled at the wire bar or rod stage, and is not concerned with assessing the quality of copper wire selected at later stages in commercial processing.
