American Society for Testing and Materials (ASTM). 1997, 6 pages.
This practice2 covers the procedures that shall be followed in eddy-current examination of copper and copperalloy tubes for detecting discontinuities of a severity likely to cause failure of the tube. These procedures are applicable for tubes with outside diameters to 31⁄8 in. (79.4 mm), inclusive,
and wall thicknesses from 0.017 in. (0.432 mm) to 0.120 in. (3.04 mm), inclusive, or as otherwise stated in ASTM product specifications; or by other users of this practice. These procedures
may be used for tubes beyond the size range recommended, upon contractual agreement between the purchaser and the manufacturer.
