1.1 This practice2 covers a procedure for applying the eddy current method to detect discontinuities in ferromagnetic pipe and tubing (Note 1) where the article being examined is rendered substantially non-magnetic by the application of a concentrated, strong magnetic field in the region adjacent to the examining coil.
Note 1: For convenience, the term tube or tubular product will hereafter be used to refer to both pipe and tubing.
