Abstract / scope
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.
