Non-destructive testing of welds - Ultrasonic testing - Techniques, testing levels, and assessment (ISO 17640:2010)
ISO 17640:2010 specifies techniques for the manual ultrasonic testing of fusion-welded joints in metallic materials of thickness greater than or equal to 8 mm which exhibit low ultrasonic attenuation (especially that due to scatter) at object temperatures from 0 °C to 60 °C. It is primarily intended for use on full penetration welded joints where both the welded and parent material are ferritic.
Where material-dependent ultrasonic values are specified in ISO 17640:2010, they are based on steels having an ultrasonic sound velocity of (5 920 ± 50) m/s for longitudinal waves and (3 255 ± 30) m/s for transverse waves.
ISO 17640:2010 specifies four testing levels, each corresponding to a different probability of detection of imperfections. Guidance on the selection of testing levels A, B, and C is given in Annex A.
ISO 17640:2010 specifies that the requirements of testing level D, which is intended for special applications, be in accordance with general requirements. Testing level D can only be used when defined by specification. This includes tests of metals other than ferritic steel, tests on partial penetration welds, tests with automated equipment, and tests at object temperatures outside the range 0 °C to 60 °C.
ISO 17640:2010 can be used for the assessment of indications, for acceptance purposes, by either of the following techniques: a) evaluation based primarily on length and echo amplitude of the signal indication; b) evaluation based on characterization and sizing of the indication by probe movement techniques.
The techniques used shall be specified.
Zerstörungsfreie Prüfung von Schweißverbindungen - Ultraschallprüfung - Techniken, Prüfklassen und Bewertung (ISO 17640:2010)
Dieses Dokument legt Verfahren zur manuellen Ultraschallprüfung von Schmelzschweißverbindungen in
metallischen Werkstoffen mit Dicken gleich und größer als 8 mm fest, die bei Temperaturen des
Prüfgegenstands von 0 °C bis 60 °C eine geringe Ultraschallschwächung zeigen (verursacht vor allem durch
Streuung). Sie gilt bevorzugt für Schweißverbindungen mit voll angeschlossenem Querschnitt, bei denen
sowohl Grundmaterial als auch Schweißgut ferritisch sind.
Alle werkstoffabhängigen Größen der Ultraschallprüfung in dieser Norm beziehen sich auf Stahl, in dem
Schall die folgenden Schallgeschwindigkeiten hat: (5 920 ± 50) m/s für Longitudinalwellen und
(3 255 ± 30) m/s für Transversalwellen.
In diesem Dokument sind vier Prüfklassen festgelegt, die unterschiedlichen Wahrscheinlichkeiten des
Nachweises von Unregelmäßigkeiten entsprechen. Hilfestellung zur Wahl der Prüfklassen A, B und C wird im
Anhang A angegeben.
Die Anforderungen der Prüfklasse D, die für besondere Anwendungen vorgesehen ist, müssen mit den
allgemeinen Anforderungen dieser Norm übereinstimmen. Die Prüfklasse D darf nur dann angewendet
werden, wenn dies in einer entsprechenden Spezifikation gefordert wird. Dies umfasst auch Prüfungen an
anderen Metallen als ferritischer Stahl, Prüfungen an Schweißnähten mit unvollständiger Durchschweißung,
Prüfungen mit automatisierten Anlagen und Prüfungen bei Temperaturen des Prüfgegenstands außerhalb des
Bereiches von 0 °C bis 60 °C.
Diese Norm darf auf Zulässigkeitsbetrachtungen für die Bewertung von Anzeigen mittels einer der folgenden
Methoden angewendet werden:
a) die Auswertung basiert vorzugsweise auf der Länge und der Echohöhe der Anzeige;
b) die Auswertung basiert auf der Charakterisierung und Größenabschätzung von Anzeigen mit Hilfe von
Abtasttechniken.
Die angewendeten Methoden müssen spezifiziert werden.
Contrôle non destructif des assemblages soudés - Contrôle par ultrasons - Techniques, niveaux d'essai et évaluation (ISO 17640:2010)
L'ISO 17640:2010 spécifie des techniques de contrôle manuel par ultrasons des assemblages en matériaux métalliques soudés par fusion, d'épaisseur égale ou supérieure à 8 mm, présentant une atténuation relativement faible des ultrasons (en particulier celle due à la diffusion) à des températures d'objet comprises entre 0 °C et 60 °C. Elle vise particulièrement les assemblages soudés à pleine pénétration dont le métal de base et la soudure sont ferritiques.
Lorsque les valeurs des caractéristiques ultrasonores dépendantes des matériaux sont précisées dans l'ISO 17640:2010, elles concernent des aciers dans lesquels la vitesse des ondes ultrasonores est égale à (5 920 ± 50) m/s pour les ondes longitudinales et (3 255 ± 30) m/s pour les ondes transversales.
L'ISO 17640:2010 spécifie quatre niveaux de contrôle, chacun correspondant à une probabilité différente de détection des défauts. Un guide du choix des niveaux de contrôle A, B et C est donné dans l'Annexe A.
L'ISO 17640:2010 spécifie que les exigences relatives au niveau de contrôle D, qui est prévu pour des applications spéciales, sont conformes aux exigences générales. Le niveau de contrôle D ne peut qu'être utilisé lorsque défini par une spécification. Cela inclut les contrôles de métaux autres que les aciers ferritiques, les contrôles sur des soudures à pénétration partielle, les contrôles avec des équipements automatisés, et les contrôles à des températures d'objet situées hors de la plage 0 °C à 60 °C.
L'ISO 17640:2010 peut être utilisée pour l'évaluation des indications, aux fins de réception, par l'une des techniques suivantes: a) évaluation fondée principalement sur la longueur et l'amplitude d'écho de l'indication du signal; b) évaluation fondée sur la caractérisation et le dimensionnement de l'indication par des techniques de déplacement du palpeur.
Les techniques utilisées doivent être spécifiées.
Neporušitveno preskušanje zvarnih spojev - Ultrazvočno preskušanje - Tehnike, stopnje sprejemlivosti in kriteriji ocenjevanja (ISO 17640:2010)
Ta evropski standard določa tehnike za ročno ultrazvočno preskušanje zvarnih spojev pri talilnem varjenju na kovinskih materialih z debelino 8 mm ali več z nizkim ultrazvočnim slabljenjem (predvsem slabljenjem zaradi razpršitve) pri temperaturah predmeta med 0 °C in 60 °C. Namenjen je predvsem uporabi pri zvarnih spojih s popolno penetracijo, pri katerih sta zvarni in matični material feritna. Kjer so v tem standardu določene od materiala odvisne ultrazvočne vrednosti, temeljijo na jeklih, ki imajo ultrazvočno hitrost zvoka 5920 ± 50 m/s za vzdolžne valove in 3255 ± 30 m/s za prečne valove.
Standard določa štiri ravni preskušanja in vsaka od njih ustreza drugačni verjetnosti odkrivanja nepravilnosti. V dodatku A je podano vodilo o izboru ravni preskušanja A, B in C.
Zahteve za raven preskušanja D, ki je namenjena posebni uporabi, so v skladu s splošnimi zahtevami tega standarda in se lahko uporabljajo le, kadar jih določa specifikacija. To vključuje preskuse kovin, ki niso feritno jeklo, preskuse na zvarih z delno penetracijo, preskuse z avtomatsko opremo in preskuse pri temperaturah predmeta zunaj razpona.
Ta standard se lahko uporabi za ocenjevanje prikazov, za namene sprejemljivosti, z eno od naslednjih tehnik:
a) Vrednotenje, ki temelji predvsem na dolžini in amplitudi odmeva signalnega prikaza,
b) Vrednotenje, ki temelji na karakterizaciji in določanju velikosti prikaza s tehnikami premikanja sond.
Določene so tudi uporabljene tehnike.

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 17640 was prepared by the European Committee for Standardization (CEN) Technical Committee
TC 121, Welding, Subcommittee SC 5, Testing of welds, in collaboration with ISO Technical Committee TC 44,
Welding and allied processes, Subcommittee SC 5, Testing and inspection of welds, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 17640:2005), which has been technically
revised.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 5 via your national standards body. A complete listing of these bodies can be
