Popis
BS EN ISO 22825:2017
This standard BS EN ISO 22825:2017 Non-destructive testing of welds. Ultrasonic testing. Testing of welds in austenitic steels and nickel-based alloys is classified in these ICS categories:
- 25.160.40 Welded joints and welds
This document 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 this document, but can be applied in accordance with the scope of the testing (see 4.1).
The requirements of this document are applicable to both manual and mechanized testing.
