(Main)Non-destructive testing of welds - Ultrasonic testing - Acceptance levels (ISO 11666:2010)
Non-destructive testing of welds - Ultrasonic testing - Acceptance levels (ISO 11666:2010)
This European Standard specifies ultrasonic acceptance levels, 2 and 3, for full penetration welded joints in ferritic steels, which correspond to the quality levels B and C of EN ISO 5817. Other acceptance levels can be used by specification.
An acceptance level corresponding to level D of EN ISO 5817 has not been included in this standard as ultrasonic testing is generally not requested for this weld quality.
These acceptance levels are applicable to testing carried out in accordance with EN 1714.
The standard is applicable to the examination of full pe¬netration ferritic steel welds, with thicknesses from 8 mm up to 100 mm. It can also be used for other types of welds, materials and thick¬nesses above 100 mm, provided the exami¬nations have been performed with necessary consi¬deration of the geometry and acoustical properti¬es of the compo¬nent and an adequate sensitivity can be employed to enable the acceptan¬ce levels of this standard to be applied. The nominal frequ¬ency of probes used in this European Standard is between 2 MHz and 5 MHz unless attenuation or require¬ments for higher resolu¬tion call for another frequen¬cy. The use of these acceptance levels in conjunction with frequen¬cies outside this range needs to be considered carefully.
Zerstörungsfreie Prüfung von Schweißverbindungen - Ultraschallprüfung - Zulässigkeitsgrenzen (ISO 11666:2010)
Diese Internationale Norm legt die Zulässigkeitsgrenzen 2 und 3 für die Ultraschallprüfung von voll durchgeschweißten
Schweißnähten in ferritischen Stählen fest, die den Bewertungsgruppen B und C von ISO 5817
entsprechen. Eine Zulässigkeitsgrenze entsprechend Bewertungsgruppe D von ISO 5817 wurde in diese
Norm nicht aufgenommen, da eine Ultraschallprüfung für Schweißnähte dieser Bewertungsgruppe im
Allgemeinen nicht verlangt wird.
Diese Zulässigkeitsgrenzen sind anwendbar für Prüfungen, die nach ISO 17640 durchgeführt werden.
Diese Internationale Norm ist anwendbar für die Prüfung von voll durchgeschweißten Schweißnähten in
ferritischen Stählen im Wanddickenbereich von 8 mm bis 100 mm. Sie kann auch für andere
Schweißnahttypen, andere Werkstoffe und Wanddicken über 100 mm angewendet werden, vorausgesetzt,
die Prüfungen wurden unter entsprechender Berücksichtigung von Geometrie und akustischen Eigenschaften
des Bauteils durchgeführt und es kann eine Prüfempfindlichkeit erreicht werden, mit der die
Zulässigkeitsgrenzen dieser Norm angewendet werden können. Die Nennfrequenz für die nach dieser
Europäischen Norm verwendeten Prüfköpfe liegt zwischen 2 MHz und 5 MHz, sofern nicht erhöhte
Schallschwächungen oder erhöhte Anforderungen an die Auflösung andere Frequenzen erfordern. Die
Anwendung dieser Zulässigkeitsgrenzen bei Prüfungen mit Frequenzen außerhalb des genannten Bereichs
bedarf zuvor einer kritischen Betrachtung.
Contrôle non destructif des assemblages soudés - Contrôle par ultrasons - Niveaux d'acceptation (ISO 11666:2010)
L'ISO 11666:2010 spécifie les niveaux d'acceptation 2 et 3 pour le contrôle par ultrasons de joints en aciers ferritiques soudés à pleine pénétration, qui correspondent aux niveaux de qualité B et C de l'ISO 5817. Il n'a pas été inclus de niveau d'acceptation correspondant au niveau de qualité D de l'ISO 5817 dans l'ISO 11666:2010 car le contrôle par ultrasons n'est généralement pas demandé pour cette qualité de soudure.
Ces niveaux d'acceptation sont applicables aux contrôles effectués conformément à l'ISO 17640.
L'ISO 11666:2010 est applicable au contrôle de joints soudés à pleine pénétration en aciers ferritiques, d'épaisseurs allant de 8 mm à 100 mm. Elle peut également être utilisée pour d'autres types de soudures, de matériaux et pour des épaisseurs supérieures à 100 mm, dans la mesure où les contrôles ont été effectués en tenant compte de la géométrie et des caractéristiques acoustiques de l'élément soudé, et où une sensibilité appropriée peut être utilisée pour permettre l'application des niveaux d'acceptation de l'ISO 11666:2010. La fréquence nominale des palpeurs utilisés dans l'ISO 11666:2010 est comprise entre 2 MHz et 5 MHz, à moins que l'atténuation ou les exigences d'une meilleure résolution ne justifient une autre fréquence. L'adoption de ces niveaux d'acceptation en utilisant des fréquences situées en dehors de cette plage nécessite d'être étudiée avec soin.
Neporušitveno preskušanje zvarnih spojev - Ultrazvočno preskušanje - Stopnje sprejemljivosti (ISO 11666:2010)
Ta evropski standard določa stopnji ultrazvočne sprejemljivosti 2 in 3, za zvarne spoje s popolno penetracijo, kar ustreza kakovostnim stopnjam B in C v EN ISO 5817. Glede na specifikacijo se lahko uporabijo druge stopnje sprejemljivosti.
Stopnja sprejemljivosti, ki ustreza stopnji D v EN ISO 5817, ni vključena v ta standard, ker se na splošno za tako kakovost zvarnih spojev ultrazvočno preskušanje ne zahteva.
Te stopnje sprejemljivosti veljajo za preskušanje, opravljeno v skladu z EN 1714.
Standard velja za pregled zvarnih spojev feritnega jekla s popolno penetracijo debeline med 8 mm in 100 mm. Uporablja se lahko tudi za druge vrste zvarnih spojev, materialov in debeline nad 100 mm, če so pregledi opravljeni s potrebnim upoštevanjem geometrije in akustičnih lastnosti komponente; lahko se uporabi ustrezna občutljivost, ki omogoča uporabo stopnje sprejemljivosti tega standarda. Nazivna frekvenca sond, uporabljenih v tem evropskem standardu, je med 2 MHz in 5 MHz, razen če je zaradi slabljenja ali zahtev po višji ločljivosti potrebna druga frekvenca. Uporabo teh stopenj sprejemljivosti v povezavi s frekvencami zunaj navedenega razpona je treba skrbno preučiti.

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 11666 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).

Non-destructive testing of welds — Ultrasonic testing —
Acceptance levels
1 Scope
This International Standard specifies ultrasonic acceptance levels 2 and 3 for full penetration welded joints in
ferritic steels, which correspond to ISO 5817 quality levels B and C. An acceptance level corresponding to
ISO 5817 quality level D is not included in this International Standard as ultrasonic testing is generally not
requested for this weld quality.
These acceptance levels are applicable to testing carried out in accordance with ISO 17640.
This International Standard applies to the examination of full penetration ferritic steel welds, with thicknesses
from 8 mm to 100 mm. It can also be used for other types of welds, materials and thicknesses above 100 mm,
provided the examinations have been performed with necessary consideration of the geometry and acoustic
properties of the component, and an adequate sensitivity can be employed to enable the acceptance levels of
this International Standard to be applied. The nominal frequency of probes used in this International Standard
is between 2 MHz and 5 MHz unless attenuation or requirements for higher resolution call for other
frequencies. The use of these acceptance levels in conjunction with frequencies outside this range needs to
be considered carefully.
