Abstract :
Ultrasonic beam parameters from nondestructive testing probes and respective measurement uncertainties were calculated according to the Guide to the Expression of Uncertainty in Measurement (BIPM-JCGM-100:2008). The major conclusion of this work is that proper measurements of ultrasonic probes parameters are necessary because each probe has intrinsic construction particularities. Uncertainty evaluation was essential to properly assess the experimental results.
