EN ISO 10863:2011

Non-destructive testing of welds - Ultrasonic testing - Use of time-of-flight diffraction technique (TOFD) (ISO 10863:2011)

ISO 10863:2011 specifies the application of the time-of-flight diffraction (TOFD) technique to the semi- or fully automated ultrasonic testing of fusion-welded joints in metallic materials of minimum thickness 6 mm. It applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and parent material are low-alloyed carbon steel. Where specified and appropriate, TOFD can also be used on other types of materials that exhibit low ultrasonic attenuation (especially that due to scatter).
Where material-dependent ultrasonic parameters are specified in ISO 10863:2011, they are based on steels having a sound velocity of (5 920 ± 50) m/s for longitudinal waves, and (3 255 ± 30) m/s for transverse waves. It is necessary to take this fact into account when examining materials with a different velocity.
ISO 10863:2011 makes reference to the basic standard EN 583‑6 and provides guidance on the specific capabilities and limitations of TOFD for the detection, location, sizing and characterization of discontinuities in fusion-welded joints. TOFD can be used as a stand-alone method or in combination with other NDT methods or techniques, for manufacturing inspection, and for in-service inspection.
ISO 10863:2011 specifies four testing levels (A, B, C, D) in accordance with ISO 17635 and corresponding to an increasing level of inspection reliability. Guidance on the selection of testing levels is provided.
ISO 10863:2011 permits assessment of TOFD indications for acceptance purposes. This assessment is based on the evaluation of transmitted, reflected and diffracted ultrasonic signals within a generated TOFD image.
ISO 10863:2011 does not include acceptance levels for discontinuities.

Zerstörungsfreie Prüfung von Schweißverbindungen - Ultraschallprüfung - Anwendung der Beugungslaufzeittechnik (TOFD) (ISO 10863:2011)

Dieses Dokument legt die Anwendung der Beugungslaufzeit- (TOFD-)Technik bei der halb- oder vollautomatisierten
Ultraschallprüfung von Schmelzschweißverbindungen in metallischen Werkstoffen mit einer Dicke
von mindestens 6 mm fest. Es gilt für durchgeschweißte Verbindungen mit einfacher Geometrie in Platten,
Rohren und Behältern, bei denen sowohl der Werkstoff der Schweißnaht als auch der Grundwerkstoff niedrig
legierter Kohlenstoffstahl ist. Sofern festgelegt und angemessen, kann die TOFD-Technik auch auf andere
Werkstoffarten angewendet werden, die eine geringe Schallschwächung aufweisen (dies gilt insbesondere für
die durch Streuung verursachte Schallschwächung).
Sofern in diesem Dokument werkstoffabhängige Ultraschallparameter festgelegt sind, beruhen diese auf
Stählen mit einer Schallgeschwindigkeit von (5 920 ± 50) m/s für Longitudinalwellen und (3 255 ± 30) m/s für
Transversalwellen. Dies ist bei der Prüfung von Werkstoffen mit anderer Schallgeschwindigkeit zu
berücksichtigen.
Dieses Dokument nimmt Bezug auf die Grundnorm EN 583-6 und liefert einen Leitfaden hinsichtlich der
besonderen Fähigkeiten und Einschränkungen der TOFD-Technik beim Auffinden, der Ortung, dem Ausmessen
und der Charakterisierung von Inhomogenitäten in Schmelzschweißverbindungen. Die TOFD-Technik
kann selbständig oder in Verbindung mit weiteren Verfahren oder Techniken der zerstörungsfreien Prüfung
(ZfP) sowohl für die Prüfung während der Herstellung als auch für die Prüfung während des Betriebs
angewendet werden.
Dieses Dokument legt vier Prüfklassen (A, B, C, D) nach ISO 17635 fest, die einem zunehmenden Grad der
Zuverlässigkeit der Prüfung entsprechen. Ein Leitfaden für die Auswahl der Prüfklassen wird bereitgestellt.
Dieses Dokument erlaubt die Beurteilung von TOFD-Anzeigen zur Bestimmung der Zulässigkeit. Diese
Beurteilung beruht auf der Bewertung durchgelassener, reflektierter und gebeugter Ultraschallsignale in einem
erzeugten TOFD-Bild.
Dieses Dokument enthält keine Zulässigkeitsgrenzen für Inhomogenitäten.

Contrôle non destructif des assemblages soudés - Contrôle par ultrasons - Utilisation de la technique de diffraction des temps de vol (méthode TOFD) (ISO 10863:2011)

L'ISO 11320:2011 spécifie l'application de la technique de diffraction des temps de vol (méthode TOFD, time-of-flight diffraction) pour le contrôle par ultrasons semi-automatique ou entièrement automatique des assemblages soudés par fusion de matériaux métalliques d'épaisseur minimale de 6 mm. Cette technique s'applique aux joints soudés à pleine pénétration de géométrie simple sur plaques, aux tubes et aux récipients, dans lesquels le métal de base et le métal fondu sont tous les deux constitués d'acier au carbone faiblement allié. Dans le cas où son utilisation est spécifiée et qu'elle s'avère appropriée, la méthode TOFD peut également être utilisée sur d'autres types de matériaux qui présentent une atténuation ultrasonore faible (spécialement celle due à la dispersion).
Lorsque les paramètres ultrasonores dépendant du matériau sont spécifiés dans la présente Norme internationale, ils sont basés sur les aciers qui présentent une vitesse de propagation sonore de (5 920 ± 50) m/s pour les ondes longitudinales et de (3 255 ± 30) m/s pour les ondes transversales. Il est nécessaire de prendre cela en compte lors de l'examen de matériaux ayant des vitesses de propagation différentes.
L'ISO 11320:2011 fait référence à la norme de base EN 583-6 et fournit des lignes directrices sur les possibilités et les limitations spécifiques de la méthode TOFD pour la détection, la localisation, le dimensionnement et la caractérisation des discontinuités dans les joints soudés par fusion. La méthode TOFD peut être utilisée de manière autonome ou en combinaison avec d'autres méthodes ou techniques de contrôle non-destructif, pour le contrôle de fabrication et pour le contrôle en cours de service.
L'ISO 11320:2011 spécifie quatre niveaux d'examen (A, B, C, D) conformément à l'ISO 17635, correspondant à des niveaux croissants de fiabilité de contrôle. Des lignes directrices relatives au choix des niveaux d'examen sont données.
L'ISO 11320:2011 permet l'évaluation des indications TOFD à des fins d'acceptation. Cette évaluation est basée sur l'appréciation des signaux ultrasonores transmis, réfléchis ou diffractés dans une image produite par la méthode TOFD.
L'ISO 11320:2011 ne comporte pas de niveaux d'acceptation pour les discontinuités.

Neporušitveno preskušanje zvarov - Ultrazvočna preiskava - Uporaba tehnike TOFD (ISO 10863:2011)

Ta dokument določa uporabo tehnike TOFD za delno ali popolnoma avtomatsko ultrazvočno preskušanje talilno zvarjenih zvarov v kovinskih materialih z debelino 6 mm in več. Uporablja se predvsem pri zvarih s popolno penetracijo na ploščah, ceveh in posodah s preprosto geometrijo, kjer sta zvar in matični material iz malo legiranega ogljikovega jekla. Kjer je določeno in primerno, se tehnika TOFD lahko uporabi tudi na drugih vrstah materialov z nizkim ultrazvočnim slabljenjem (predvsem slabljenjem zaradi razpršitve).
Kjer so v tem dokumentu določeni od materiala odvisni ultrazvočni parametri, temeljijo na jeklih, ki imajo hitrost zvoka (5920 ± 50) m/s za vzdolžne valove in (3255 ± 30) m/s za prečne valove. To je treba upoštevati pri preučevanju materialov z različno hitrostjo.
Ta dokument se sklicuje na osnovni predstandard ENV 583 6 in podaja vodilo o specifičnih zmogljivostih in omejitvah tehnike TOFD za zaznavanje, ugotavljanje lokacije in velikosti ter karakterizacijo prekinjenosti talilno zvarjenih zvarov. TOFD se lahko uporablja kot samostojna metoda ali v kombinaciji z drugimi metodami ali tehnikami neporušitvenega preskušanja za pregled proizvodnje (pred začetkom uporabe) ali za pregled med uporabo.
Ta dokument določa štiri ravni pregleda (A, B, C, D), ki pomenijo naraščajočo raven zanesljivosti pregleda. Podano je tudi vodilo za izbor ravni pregleda.
Ta dokument omogoča ocenjevanje indikacij za namene sprejemljivosti. Ta ocena temelji na vrednotenju presevanih, odbitih in lomljenih ultrazvočnih signalov v nastali sliki TOFD.
Ta dokument ne vključuje stopenj sprejemljivosti za neprekinjenosti.

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 10863 was prepared by the European Committee for Standardization (CEN) Technical Committee

This International Standard specifies the application of the time-of-flight diffraction (TOFD) technique to the
semi- or fully automated ultrasonic testing of fusion-welded joints in metallic materials of minimum thickness
6 mm. It applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both
the weld and parent material are low-alloyed carbon steel. Where specified and appropriate, TOFD can also
be used on other types of materials that exhibit low ultrasonic attenuation (especially that due to scatter).
Where material-dependent ultrasonic parameters are specified in this International Standard, they are based
