标准摘要
[中文适用范围]: 本文件给出了使用 FMC/TFM 技术和相关技术对阵列进行超声测试的一般规定。 其目的是促进在制造阶段或现有装置的在役测试或维修过程中采用良好实践。 本文件中考虑的一些应用示例涉及损坏评估中的表征和尺寸确定。 考虑的材料是低合金碳钢和常见的航空级铝和钛合金,前提是它们是均匀且各向同性的,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可接受水平。 有关 FMC/TFM 在焊缝测试中的应用,请参阅 ISO 23864。 [外文原描述]: 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.
