DIN EN 1971-2:2012-02

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. The eddy current test method(s) required, together with the size range and acceptance level, are defined in the relevant product standard. The choice of the method for eddy current test with an encircling test coil on the outer surface according to EN 1971-1 or with an internal probe on the inner surface according to 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. CEN/TC 133 "Copper and copper alloys" is responsible for this European Standard. During the preparation of this standard the national interests were represented by Working Committee NA 066-02-03 AA "Kupferrohre (Installation und Industrie)" ("Copper tubes (Installation and industrial)") of FNNE.
