In the case of testing on longitudinal imperfections, Lamb wave testing can be applied at the discretion of the manufacturer. For seamless tubes, by agreement between the purchaser and manufacturer, testing principles of ISO 10893-10:2011 can be applied to detect imperfections having other orientations. ISO 10893-10:2011 is applicable to the inspection of tubes with an outside diameter greater than or equal to 10 mm, normally with an outside diameter-to-thickness ratio greater than or equal to 5. It can also be applicable to the testing of circular hollow sections.

ISO 10893-11:2011 specifies requirements for the automated ultrasonic shear wave (generated by conventional or phased array technique) testing of the weld seam of submerged arc-welded (SAW) or electric resistance and induction-welded (EW) steel tubes. For SAW tubes, the test covers the detection of imperfections oriented predominantly parallel to or, by agreement, perpendicular to the weld seam or both. For EW tubes, the test covers the detection of imperfections oriented predominantly parallel to the weld seam. In the case of testing on longitudinal imperfections, Lamb wave testing can be applied at the discretion of the manufacturer. ISO 10893-11:2011 can also be applicable to the testing of circular hollow sections.

ISO 10893-8:2011 can also be applicable to the testing of circular hollow sections.

ISO 10893-5:2011 specifies requirements for magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of surface imperfections on the tube body and the end/bevel face at the ends. For the tube body, it specifies requirements for the detection of surface imperfections on all or part of the outside surface of tubes. However, by agreement between the purchaser and manufacturer, it can be applicable to the inside surface over a limited length from the ends of tubes, dependent on the tube diameter. In addition, ISO 10893-5:2011 can be used, as appropriate, to locate the position of external surface imperfections detected by another non-destructive testing method (e.g. ultrasonic) prior to dressing of the tube surface, and to ensure complete removal of the imperfection after dressing is complete. For the end/bevel face at the ends of plain-end and beveled-end tubes, ISO 10893-5:2010 specifies requirements for the detection of laminar imperfections which can interfere with subsequent fabrication and inspection operations (e.g. welding and ultrasonic inspection of the welds). ISO 10893-5:2011 is applicable to the detection of imperfections, other than laminar imperfections, on the end/bevel face. In this case, magnetization is applied in the direction essentially perpendicular to the orientation of the particular imperfections being detected. It can also be applicable to the testing of hollow sections.

ISO 10332:2010 is applicable to the inspection of tubes with an outside diameter greater than or equal to 10 mm, and with an outside diameter-to-thickness ratio greater than or equal to 5.
