This part of ISO 10893 specifies requirements for automated electromagnetic testing of seamless and welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for verification of hydraulic leaktightness. It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm, when testing with eddy current, and greater than 10 mm when testing with flux leakage method. This part of ISO 10893 can also be applicable to the testing of hollow sections. NOTE Electromagnetic inspection using magnetic flux leakage method is not applicable to austenitic stainless steel tubes.
