ISO 22825:2017 specifies the approach to be followed when developing procedures for the ultrasonic testing of the following welds:- welds in stainless steels;- welds in nickel-based alloys;- welds in duplex steels;- dissimilar metal welds;- austenitic welds.The purposes of the testing can be very different, for example:- for the assessment of quality level (manufacturing);- for the detection of specific discontinuities induced in service.Acceptance levels are not included in ISO 22825:2017, but can be applied in accordance with the scope of the testing (see 4.1).The requirements of ISO 22825:2017 are applicable to both manual and mechanized testing.
