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.
