ActiveNon-destructive testing—Ultrasonic testing—Transmission technique
无损检测 超声检测 穿透技术
Application Summary AI generated
This standard specifies the methodology for ultrasonic testing using the transmission technique, where two transducers are placed on opposite sides of a test object to evaluate material integrity based on signal attenuation. It is applied in industrial non-destructive testing contexts, such as inspecting composite materials, bonded structures, or plates for internal defects like delaminations, disbonds, or porosity. The standard is particularly relevant for quality control in aerospace, automotive, and manufacturing sectors where through-transmission ultrasound is preferred over pulse-echo methods for certain geometries or materials.
