ActiveNon-destructive testing—Ultrasonic testing—Reference blocks and test procedures for the characterization of contact probe sound beams
无损检测 超声检测 测量接触探头声束特性的参考试块和方法
Application Summary AI generated
This standard specifies the design, material, and dimensional requirements for reference blocks used to characterize the sound beam properties of contact ultrasonic probes, as well as the test procedures for measuring beam parameters such as focal length, beam width, and sensitivity. It is applied in non-destructive testing laboratories and industrial inspection environments, particularly for quality control and calibration of ultrasonic equipment used in manufacturing, aerospace, and heavy machinery sectors. The standard ensures consistent probe performance evaluation across different testing setups, enabling reliable flaw detection and thickness measurements in metallic and composite materials.
