Sensitivity
The ability of an NDT method to detect discontinuities of a specified minimum size under defined conditions. Higher sensitivity means smaller defects can be detected. Sensitivity is affected by material properties, transducer characteristics, equipment settings, and technique. Standards specify minimum sensitivity requirements for different applications. Establishing sensitivity through reference standards ensures consistency and reliability of inspections.
