ISO 10893-10:2010 specifies requirements for automated full peripheral ultrasonic shear wave (generated by conventional or phased array technique) testing of seamless and welded [except submerged arc-welded (SAW)] steel tubes, for the detection of longitudinal and transverse imperfections. 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 10893-10:2010 can be applied to detect imperfections having other orientations. ISO 10893-10:2010 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.
