摘要：In the article we deal with the issue of non-destructive diagnostics of a specified part on the railway, namely the rail. The chapters are devoted to the non-destructive defectoscopic method, or more precisely an ultrasonic test, which is performed by DIO 562 device and it also includes data processing from the measurement. The article briefly describes location and character of defects on the rails and actual process of measurement. The measurement was performed on a standard length of 10 km, with the use of a device capable of copying shape of the rails during the ultrasonic examination. The evaluation of the measurement was processed in specialized software DIO 2000 on the PC. Based on this evaluation, three manual inspections were implemented to determine the character of defects. The conclusion of this article is a precise determination of character and origin of these selected defects, and suggestion for their removal or replacement according to the valid regulations.
