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 16823 was prepared by Technical Committee ISO/TC 135, Non-destructive testing, Subcommittee SC 3,

technique
1 Scope
This International Standard specifies the principles of transmission techniques.
Transmission techniques can be used for:
⎯ detection of imperfections;
⎯ determination of attenuation.
The general principles required for the use of ultrasonic examination of industrial products are described in
ISO 16810.
The transmission technique is used for examination of flat products, e.g. plates and sheets.
Further, it is used for examinations e.g.:
⎯ where the shape, dimensions or orientation of possible imperfections are unfavourable for direct
reflection;
⎯ in materials with high attenuation;
⎯
