Paper presents characteristics of thermovision, 3D scanning and tomography methods used for quality rating in multilayer ceramic moulds used for purposes of aircraft turbine blades casting. Moulds measurements were performed with thermovision camera, 3D scanner and tomography. Results were converted via dedicated software for each method and were saved in compatible file format that allowed to perform an analysis. One of the decisive factors of these measurement methods usefulness are accuracy and measurement error. For obtained measurement results quality rating selected statistical methods, Measurement System Analysis MSA and R&R index were used. Analysis allowed to estimate uncertainty and efficiency for applied non-destructive measurement systems for multilayer ceramic moulds rating.Keywords: Methods NDT, thermovision, 3D scanning, tomography, uncertainty, multilayer ceramic moulds
