This document (EN ISO 13588:2012) has been prepared by Technical Committee CEN/TC 121 "Welding", the secretariat of which is held by DIN (Germany) in collaboration with Technical Committee ISO/TC 44 "Welding and allied processes" in accordance with the Vienna Agreement. The responsible German committee is Working Committee NA 062-08-23 AA "Ultraschallprüfung" ("Ultrasonic testing") at the Materials Testing Standards Committee (NMP). This International Standard specifies the application of the phased array technology for the semi- or fully automated ultrasonic testing of fusion-welded joints in metallic materials of minimum thickness 6 mm. It applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and parent material are low-alloyed carbon steel. Where material-dependent ultrasonic parameters are specified in this International Standard, they are based on steels having an ultrasonic sound velocity of (5 920 ± 50) m/s for longitudinal waves, and (3 255 ± 30) m/s for transverse waves. It is necessary to take this fact into account when examining materials with a different sound velocity. This International Standard provides guidance on the specific capabilities and limitations of phased array technology for the detection, location, sizing and characterization of discontinuities in fusion-welded joints. Phased array technology can be used as a stand-alone technology or in combination with other non-destructive testing (NDT) methods or techniques, for manufacturing inspection, pre-service and for in-service inspection. This International Standard specifies four testing levels, each corresponding to a different probability of detection of imperfections. This International Standard permits assessment of indications for acceptance purposes based on either amplitude (equivalent reflector size) and length or height and length. This International Standard does not specify acceptance levels for discontinuities. This International Standard is not applicable: - for coarse-grained metals and austenitic welds; - for automated testing of welds during the production of steel products covered by ISO 10893-8, ISO 10893-11, and ISO 3183.
