Non-destructive testing - Ultrasonic testing - Through-transmission technique (ISO/DIS 16823:2024)
ISO 16823:2012 specifies the principles of through-transmission techniques.
Through-transmission techniques can be used for: a) detection of imperfections; b) determination of attenuation.
The general principles required for the use of ultrasonic testing of industrial products are described in ISO 16810.
The through-transmission technique is used for testing of flat products, e.g. plates and sheets.
Further, it is used for testings e.g.: 1) where the shape, dimensions or orientation of possible imperfections are unfavourable for direct reflection; 2) in materials with high attenuation; 3) in thin products.

L'ISO 16823:2012 spécifie les principes des techniques de transmission.
Les techniques de transmission peuvent être utilisées pour la détection de discontinuités et la détermination de l'atténuation.
Les principes généraux exigés pour l'utilisation du contrôle par ultrasons de produits industriels sont décrits dans l'ISO 16810.
La technique par transmission est utilisée pour le contrôle de produits plats, par exemple plaques et tôles.
Elle est également utilisée pour l'examen d'éventuelles discontinuités dont la forme, les dimensions ou l'orientation sont défavorables au contrôle par réflexion, de matériaux à atténuation élevée et de produits minces.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 135, Non-destructive testing,
Subcommittee SC 3, Ultrasonic testing.
This second edition cancels and replaces the first edition (ISO 16823:2012), which has been technically
revised.
The main changes are as follows:
— normative references have been updated;
— figures have been improved;
— the terminology has been aligned throughout the whole document.

1 Scope
This document specifies the principles of ultrasonic through-transmission techniques.
Through-transmission techniques can be used for:
— detection of imperfections;
— determination of sound attenuation.
The general principles required for the use of ultrasonic testing of industrial products are described in
ISO 16810.
The through-transmission technique is used for the testing of flat products, e.g. plates and sheets.
Further, it can be used for tests, e.g.:
— where the shape, dimensions or orientation of possible imperfections are unfavourable for direct
reflection;
— of materials with high sound attenuation;
— on thin test objects.
