SRPS EN ISO 22825:2017

Non-destructive testing of welds - Ultrasonic testing - Testing of welds in austenitic steels and nickel-based alloys (ISO 22825:2017)

Scope

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.
