The scope of the journal is aimed to all methods and techniques of non-destructive and destructive testing, as well as evaluation of materials and structures in all areas of technical activities. It is an opportunity to publish research and development results, together with good practices and recommendations for standardization. Submitted manuscripts should not have been published previously and should not be currently under consideration for publishing elsewhere. They should be prepared in accordance with the Instructions for Authors, published on the journal site. The articles appearing in the Journal are indexed in NDT Net.
