Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22825 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 121, Welding, in collaboration with Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 5, Testing and inspection of welds, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).

ISO 22825:2006(E)
Introduction
Austenitic steel and dissimilar metal welds are widely regarded as very difficult to inspect by ultrasonics. The
problems are mainly associated with unfavourable microstructure and grain size, as well as with different
material properties which result in inhomogeneous and anisotropic mechanical and acoustic properties that
contrast with the relatively homogeneous and isotropic behaviour in low-alloy steel welds.
Because the austenitic weld metal affects ultrasound propagation, it is necessary to produce a reference block
in order to develop a testing procedure, set a preliminary sensitivity level, assess the procedure and
demonstrate effectiveness before a definitive procedure is written. Material, weld preparation and welding
procedure, as well as the geometry and surface condition of reference blocks, are normally the same as for
the component being tested.
Since austenitic and dissimilar metal welds present greater challenges for ultrasonic testing than do ferritic
ones, ultrasonic testing in all its phases (planning, performance and data evaluation) requires more attention.
This International Standard specifies the approach to be followed when developing procedures for the
ultrasonic testing of welds in austenitic steels and nickel-based alloys.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44 SC 5 via your national standards body. A complete listing of these bodies can be
found at http://www.iso.org.
