NS-EN 10246-16:2000

ADOPTED_FROM:EN 10246-16:2000 This Part of EN 10246 specifies requirements for the ultrasonic testing of the area adjacent to the weld of welded steel tubes for the detection of laminar imperfections. The standard specifies acceptance levels and calibration procedures NOTE: This inspection may alternatively, in accordance with EN 10246-15, be carried out on longitudinal edges of strip/plate (used in the manufacture of welded tubes) in the flat form prior to seam welding. Electric welded tubes may alternatively be inspected in accordance with EN 10246-14 assuming that the scanning coverage used is sufficient to detect the minimum imperfection length given in table 1. This Part of EN 10246 is applicable to the inspection of welded tubes with an outside diameter greater than 30 mm. No lower limit of wall thickness is specified but see note in 4.1. European Standard EN 10246 "Non-destructive testing of steel tubes" comprises the parts shown in Annex A.
