1 Scope 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. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. CEN/TS 14751, Welding — Use of time-of-flight diffraction technique (TOFD) for examination of welds EN ISO 5817, Welding — Fusion-welded joints in steel, nickel, titanium and their alloys (beam welding excluded) — Quality levels for imperfections (ISO 5817:2003, corrected version:2005, including Technical Corrigendum 1:2006) 3 Symbols, terms and definitions 3.1 Symbols h height of an indication (see Figures 1, 2 and 3) l length of an indication (see Figures 1, 2 and 3) t nominal wall thickness in accordance with construction drawing or dimension table
