Abstract
U ovom diplomskom radu, teoretski i eksperimentalno, opisano je i provedeno ispitivanje sposobnosti za nerazorno ultrazvučno mjerenje debljine stijenke. U teorijskom dijela rada opisane su glavne značajke ultrazvučne metode zajedno s tehničkim zahtjevim za ultrazvučno mjerenje debljine. Naglasak je stavljen na specifičnostima ispitnih uzoraka, koji utječu na točnost mjerenja. Detaljnije je opisana tehnika odjeka, kao najčešće korištena (uključujući i eksperimentalnio dio rada) tehnika mjerenja debljine stijenke. Teorijski dio obuhvaća i pregled svih relevantnih normi za ispitivanje sposobnosti te prema kojima je osmišljena međulaboratorijska usporedba u eksperimentalnom dijelu. Također, detaljnije je prikazan način provođenja ispitivanja sposobnosti s istaknutim važnostima i razlozima njihove provedbe. U eksperimentalnom dijelu rada osmišljena je shema ispitivanja sposobnosti, provedena su mjerenja na 4 uzorka od strane 5 laboratorija te su statistički obrađeni dobiveni rezultati prema normi HRN EN ISO/IEC 17043:2010. Obuhvaćeni su svi važni aspekti ispitivanja sposobnosti u ultrazvučnom mjerenju debljina stijenke, kao što su korišteni ispitni uzorci, postupak ispitivanja i postupak ocjenjivanja njihove osposobljenosti i dokazivanja pouzdanosti njihovih rezultata.
Abstract (english)
In this thesis, theoretically and experimentally, a proficiency testing of ultrasonic thickness measurement was described and performed. The theoretical part of the paper describes the main characteristics of the ultrasonic method along with the technical requirements for ultrasonic thickness measurement. Focus is placed on the specifics of the specimens, which affect the accuracy of the measurement. In more detail, the pulse-echo technique is described, as the most commonly used (including the experimental part of the paper) thickness measurement technique. The theoretical part also includes an overview of all relevant standards for proficiency testing and according to which an interlaboratory comparison in the experimental part is designed. Also, the importance and reasons for the implementation of proficiency testing are described in more detail. In the experimental part of the thesis, the proficiency testing scheme was designed, measurements on 4 samples by 5 laboratories were performed and the obtained results were statistically processed, according to the standard HRN EN ISO/IEC 17043: 2010. It also covers all important aspects of proficiency testing of ultrasonic thickness measurements, such as the specimens used, the test procedure and the assessment procedure for assessing their competence and proving the reliability of their results.
