1.	In ultrasonic inspection, some standards are taken as a reference to measure the size of discontinuity in the material.(a) True(b) FalseI had been asked this question by my school principal while I was bunking the class.I'm obligated to ask this question of Inspection Procedures in division Inspection Testing in Foundries of Casting-Forming-Welding I
Answer» Right option is (a) True The BEST explanation: In ultrasonic inspection, the instrument is adjusted using a series of REFERENCE standards in the form of cylindrical BLOCKS containing some flat bottom holes of specified sizes at DIFFERENT depths. So the discontinuity size is easily determined by comparing the reflected signal amplitude with that reflected by a flat bottom hole at a SIMILAR depth.
