This International Standard 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). This International Standard is primarily intended for full penetration welded joints where both the welded and parent materials are ferritic. This International Standard specifies four testing levels (A, B, C and D) (see Clause 11), each corresponding to a different probability of detection of imperfections. Rules for the selection of testing levels A, B and C are given in Annex A. This International Standard may be used for assessment of indications, for acceptance purposes, by either of the following methods: a) evaluation based primarily on length and echo amplitude of the signal indication; b) evaluation based on characterization and sizing of the indication by probe movement methods. The techniques described in this International Standard may be specified, for example in an application standard, for use with: - materials other than those stated, - partial-penetration welds, - automated equipment. In each case, the technique should be verified as having adequate sensitivity.
