scope:

This part of ISO 10893 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/or transversal imperfections. Unless otherwise specified in the purchase order, the testing method is applied for the detection of predominantly longitudinal imperfections. In the case of testing on longitudinal imperfections, Lamb wave testing may be applied at the discretion of the manufacturer. For seamless tubes, by agreement between purchaser and manufacturer, testing principles of this international standard may be applied to detect imperfections having other orientations. This document 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 or equal to 5.
