Standard Practice for Electromagnetic (Eddy-Current) Examination of Copper Redraw Rod for Electrical Purposes

1.1 This practice covers the procedures that shall be followed in electromagnetic (eddy-current) examination of copper redraw rods for detecting discontinuities or imperfections of a severity likely to cause failure or markedly impair surface quality of the rod. These procedures are applicable for continuous lengths of redraw rod in diameters from 1/4 to 1 3/8 in. (6.4 to 35 mm) suitable for further fabrication into electrical conductors.

1.2 This practice covers redraw rod made from tough-pitch or oxygen-free coppers.

1.3 The procedures described in this practice are based on methods for making use of stationary encircling annular test coil systems.

1.4 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents of inch-pound units may be approximate.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
