This European Standard specifies a procedure for the eddy current test with an internal probe for measuring defects on the inner surface of seamless round copper and copper alloy tubes. This European Standard applies particularly for finned tubes with high fins according to EN 12452. The choice of the method for eddy current test: - with an encircling test coil on the outer surface according EN 1971-1 or - with an internal probe on the inner surface according EN 1971-2 is at the discretion of the manufacturer if there are no other agreements between the purchaser and the supplier. Especially for finned tubes according to EN 12452 with high fins, it is recommended to use eddy current test with internal probe as described in this standard.
