本文件给出了使用FMC/TFM技术和相关技术对阵列进行超声波检测的一般规定。其目的是促进在制造阶段或现有装置的运行测试或维修中采用良好做法。 本文件中考虑的一些应用示例涉及损伤评估中的特征描述和尺寸确定。 考虑的材料为低合金钢和普通航空航天级铝和钛合金，前提是它们均匀且各向同性，但对其他材料（例如奥氏体材料）给出了一些建议。 本文件不包括不连续性的验收等级。 有关FMC/TFM在焊缝测试中的应用，请参见ISO 23864。

This document gives general provisions for applying ultrasonic testing with arrays using FMC/TFM techniques and related technologies. It is intended to promote the adoption of good practice either at the manufacturing stage or for in-service testing of existing installations or for repairs. Some examples of applications considered in this document deal with characterization and sizing in damage assessment. Materials considered are low-alloyed carbon steels and common aerospace grade aluminium and titanium alloys, provided they are homogeneous and isotropic, but some recommendations are given for other materials (e.g. austenitic ones). This document does not include acceptance levels for discontinuities. For the application of FMC/TFM to testing of welds, see ISO 23864.
