Assessment of ultrasonic reference block calibration methodology
Abstract
The state of the art in aluminum ultrasonic reference block calibration practices is reviewed, especially as it has been guided by the recommended practices of the American Society for Testing and Materials for aluminum blocks. The principal system variable in the calibration procedures are identified, and recommendations for reducing their associated measurement errors are made. Quantitative evaluations of the limitations to improving measurement precision are made in light of present technology. Suggestions for improving present practices are made, and extensive reference to the relevant technical literature is made.
