Non-destructive testing of welds - Time-of-flight diffraction technique (TOFD) - Acceptance levels (ISO 15626:2018)
This document specifies acceptance levels for the time‑of‑flight diffraction technique (TOFD) of full
penetration welds in ferritic steels from 6 mm up to 300 mm thickness which correspond to the quality
levels of ISO 5817.
These acceptance levels are applicable to indications classified in accordance with ISO 10863.

Dieses Dokument legt die Zulässigkeitsgrenzen fest für die Prüfung von durchgeschweißten Verbindungen von ferritischen Stählen mit einer Dicke von 6 mm bis 300 mm mittels Beugungslaufzeittechnik (TOFD), die den Qualitätsanforderungen in ISO 5817 entsprechen.
Diese Zulässigkeitsgrenzen sind anwendbar auf Anzeigen, die nach ISO 10863 eingestuft wurden.
Essais non destructifs des assemblages soudés - Technique de diffraction des temps de vol (méthode TOFD) - Niveaux d'acceptation (ISO 15626:2018)
Le présent document spécifie les niveaux d'acceptation pour la technique de diffraction des temps de vol (méthode TOFD) utilisée sur des joints soudés à pleine pénétration pratiqués sur des aciers ferritiques d'épaisseur comprise entre 6 mm et 300 mm, correspondant aux niveaux de qualité énoncés dans l'ISO 5817.
Ces niveaux d'acceptation sont applicables à des indications classifiées conformément à l'ISO 10863.
Neporušitveno preskušanje zvarnih spojev - Tehnika TOFD - Stopnje sprejemljivosti (ISO 15626:2018)
Ta dokument določa stopnje sprejemljivosti za tehniko TOFD, namenjeno za zvarne spoje s popolno prevaritvijo pri feritnih jeklih debeline od 6 mm do 300 mm, ki ustrezajo stopnjam sprejemljivosti iz standarda ISO 5817.
Te stopnje sprejemljivosti se uporabljajo za indikacije, razvrščene v skladu s standardom ISO 10863.

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.o rg/patents).
