标准摘要
[中文适用范围]： 本标准规定了铁素体钢厚度从6 mm至300 mm的全熔透焊缝的飞行时间衍射技术（TOFD）的验收等级，这些等级对应于ISO 5817的质量等级。这些验收等级适用于按照ISO 10863分类的缺陷。 [外文原描述]： This document 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 ISO 5817. These acceptance levels are applicable to indications classified in accordance with ISO 10863.
