This Part of EN 10246 specifies requirements for automatic ultrasonic testing of seamless
and welded steel tubes, with the exception of submerged arc welded (SAW) tubes, for the
detection of laminar imperfections. The standard specifies acceptance levels and
calibration procedures.
NOTE : An alternative test method for the detection of laminar imperfections in
steel strip/plate prior to tube forming of welded tubes, is given in EN
10246-15.
This Part of EN 10246 is applicable to the inspection of 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.
