ISO 22825:2017

Non-destructive testing of welds — Ultrasonic testing — Testing of welds in austenitic steels and nickel-based alloys

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.
