ISO 22825:2006 PDF

ISO 22825:2006 specifies the approach to be followed when developing procedures for the ultrasonic testing of the following welds: welds in austenitic stainless steels; welds in nickel-based alloys; welds in duplex steels; dissimilar metal welds. The purposes of the testing can be very different, e.g.: for the assessment of quality level (manufacturing); for the detection of specific indications induced in service. Acceptance levels are not included in ISO 22825:2006, but can be applied in accordance with the scope of the testing. The requirements of ISO 22825:2006 are applicable to both manual and mechanized testing.
