<p>ISO 17640:2005 specifies methods for manual ultrasonic testing of fusion-welded joints in metallic materials, greater than or equal to 8 mm thick, which exhibit low ultrasonic attenuation (especially that due to scatter). It is primarily intended for full penetration welded joints where both the welded and parent materials are ferritic.</p>
<p>It specifies four testing levels (A, B, C and D), each corresponding to a different probability of detection of imperfections.</p>
