(Main)Non-destructive examination of welds - Ultrasonic examination of welded joints - Acceptance levels
Non-destructive examination of welds - Ultrasonic examination of welded joints - Acceptance levels
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 25817, respectively. Other acceptance levels can be used by agreement between the contracting parties. An acceptance level corresponding to level D of EN 25817 has not been included in this standard as ultrasonic examination is not recommended for this weld quality. These acceptance levels are applicable to examinations carried out in accordance with the standards referred to in EN 12062. They can, however, be applied in conjunction with other rules, where the same types of reference reflectors for sensitivity setting are used, provided it is agreed between the contracting parties. The standard is applicable to the examination of full penetration ferritic steel welds, with thicknesses from 8 mm up 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 acoustical properties of the component and an adequate sensitivity can be employed to enable the acceptance levels of this standard to be applied. The nominal frequency of probes used in this European Standard is between 2 MHz and 5 MHz unless attenuation or requirements for higher resolution call for another frequency. The use of these acceptance levels in conjunction with frequencies outside this range needs to be considered carefully.
Zerstörungsfreie Prüfung von Schweißverbindungen - Ultraschallprüfung von Schweißverbindungen - Zulässigkeitsgrenzen
Diese Norm legt Zulässigkeitsgrenzen, 2 und 3, für die Ultraschallprüfung von voll durchgeschweißten Stumpfnähten in ferritischen Stählen fest, die den Bewertungsgruppen B und C von EN 25817 entsprechen. Es können auch andere Zulässigkeitsgrenzen nach Vereinbarung zwischen den Vertragspartnern benutzt werden. Eine Zulässigkeitsgrenze entsprechend Bewertungsgruppe D von EN 25817 wurde in dieser Norm nicht aufgenommen, da eine Ultraschallprüfung für Schweißnähte dieser Bewertungsgruppen nicht empfohlen wird.
Contrôles non destructif des assemblages soudés - Contrôle par ultrasons des assemblages soudés - Niveaux d'acceptation
La présente norme européenne spécifie les niveaux d'acceptation 2 et 3 pour l'examen par ultrasons de joints en aciers ferritiques soudés à pleine pénétration, qui correspondent aux niveaux B et C de l' EN 25817. D'autres niveaux d'acceptation peuvent être utilisés par accord entre les parties contractantes. Les niveaux d'acceptation correspondant au niveau D de l'EN 25817 n'ont pas été inclus dans la présente norme car l'examen par ultrasons n'est pas recommandé pour cette qualité de soudure.
