标准摘要
[中文适用范围]： 本文件规定了壁厚范围为 3.2 mm 至 8 mm 的低合金和/或细晶钢全熔透焊缝的相控阵超声检测技术 (UT-PA) 的验收水平，对应于ISO 5817 的质量水平。 这些验收水平适用于根据 ISO 20601 检测到的迹象。 [外文原描述]： This document specifies acceptance levels for the phased array ultrasonic testing technique (UT-PA) of full-penetration welds in low-alloy and/or fine-grained steels in the wall thickness range from 3,2 mm to 8 mm which correspond to the quality levels of ISO 5817. These acceptance levels are applicable to indications detected according to ISO 20601.
