Non-destructive testing of welds. Time-of-flight diffraction technique (TOFD). Acceptance levels has-digital where there are critical time1 Scope This document specifies acceptance levels for the timeofflight 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 ISO 5817. These acceptance levels are applicable to indications classified in accordance with ISO 10863.
