Non-destructive testing — Ultrasonic testing — General principles
ISO 16810:2012 defines the general principles required for the ultrasonic examination of industrial products that permit the transmission of ultrasound. The specific conditions of application and use of ultrasonic examination, which depend on the type of product examined, are described in documents which could include: a) product standards; b) specifications; c) codes; d) contractual documents; e) written procedures. Unless otherwise specified in the referencing documents the minimum requirements of ISO 16810:2012 are applicable. ISO 16810:2012 does not define: 1) extent of examination and scanning plans; 2) acceptance criteria.
Essais non destructifs — Contrôle par ultrasons — Principes généraux
L'ISO 16810:2012 définit les principes généraux du contrôle ultrasonore des produits industriels perméables aux ondes ultrasonores. Les conditions particulières d'application et d'utilisation des contrôles ultrasonores, qui dépendent du type de produit examiné, font l'objet de documents tels que normes de produit, spécifications, codes, documents contractuels et procédures écrites. Sauf indications contraires dans les documents de référence, les exigences minimales de l'ISO 16810:2012 sont applicables. L'ISO 16810:2012 ne définit pas l'étendue des essais et des plans de contrôle et les critères d'acceptation.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
