<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The methods and good practice in XRD measurements are presented in this paper. The paper concerns the specimens made of 2024-T3 aluminium alloy plates joint together by rivets. The presented methodology can by divided into two parts: (1) general rules of XRD measurements on 2024-T3 aluminium alloy - choosing the diffraction angle, time of exposure on X-ray radiation, diameter of X-ray spot, etc. and (2) rules applied to riveted specimens - geometrical analysis of the specimen and movements of the goniometer which allow to obtain proper results of stress measurement.Short information about theoretical bases and influence of protective layers on XRD measurement is also included.In the end of the paper the additional equipment called the slit is presented, which allow to perform measurements on flat and cylindrical surfaces with higher resolution.</abstract>
