ActiveNon-destructive testing of welds—Time-of-flight diffraction technique (TOFD)—Acceptance levels
焊缝无损检测 衍射时差技术（TOFD） 验收等级
Application Summary AI generated
This standard specifies acceptance levels for evaluating weld quality using the Time-of-Flight Diffraction (TOFD) non-destructive testing technique. It is applied in manufacturing industries, particularly for steel weldments in pressure vessels, pipelines, and structural components, to determine whether detected discontinuities meet predefined quality criteria. The standard provides a consistent framework for classifying TOFD indications into acceptable or rejectable categories based on size, type, and location.
