ActiveNon-destructive testing—Ultrasonic testing—Characterization and sizing of discontinuities
无损检测 超声检测 不连续的特征和定量
Application Summary AI generated
This standard specifies methods for characterizing and sizing discontinuities (such as cracks, inclusions, or porosity) detected during ultrasonic testing. It is applied in industrial non-destructive testing contexts, including manufacturing quality control, in-service inspection of metal components, and weld evaluation, to ensure consistent and reliable defect assessment across sectors like aerospace, energy, and heavy machinery.
