(Main)Non-destructive testing of welds - Time-of-flight diffraction technique (TOFD) - Acceptance levels
Non-destructive testing of welds - Time-of-flight diffraction technique (TOFD) - Acceptance levels
This European standard 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 EN ISO 5817.
These acceptance levels are applicable to indications classified in accordance with CEN/TS 14751.
Zerstörungsfreie Prüfung von Schweißverbindungen - Beugungslaufzeittechnik (TOFD) - Zulässigkeitsgrenzen
Diese Europäische Norm legt Zulässigkeitsgrenzen für die Prüfung von durchgeschweißten Verbindungen von ferritischen Stählen zwischen 6 mm und 300 mm mittels Beugungslaufzeittechnik (TOFD), die den Qualitäts¬anforderungen in EN ISO 5817 entsprechen, fest.
Diese Zulässigkeitsgrenzen sind anwendbar auf Anzeigen, die nach CEN/TS 14751 eingestuft wurden.
Essais non destructifs des assemblages soudés - Technique de diffraction des temps de vol (méthode TOFD) - Niveaux d'acceptation
La présente Norme européenne 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’EN ISO 5817.
Ces niveaux d’acceptation sont applicables à des indications classifiées conformément à la Spécification
technique CEN/TS 14751.
