Measurement services for ultrasonic non-destructive evaluation

Acoustic emission and pulse echo ultrasonic techniques offer great potential for detecting and evaluating materials defects nondestructively. However, these methods are sensitive to measurement system characteristics and to the condition of the reference artifacts used. An effort to improve the reli...

Description
Summary:Acoustic emission and pulse echo ultrasonic techniques offer great potential for detecting and evaluating materials defects nondestructively. However, these methods are sensitive to measurement system characteristics and to the condition of the reference artifacts used. An effort to improve the reliability and diminish the uncertainty of these techniques is underway at the National Bureau of Standards. Part of this effort has focused on the development of measurement services for transducers and reference blocks. The measurement services now available from NBS are described below:
