摘要：

The research analyses some possibilities for automated processing of data from measuring the nondestructive testing characteristics: thermo-electromotive force (E-MF) and magnetic noise (MN), also known as Barkhausen noise (NB), represented respectively by the parameters: thermo-electromotive voltage ET and magnetic noise voltage E-NB, in samples of metals and alloys. Mathematical algorithms for developing software for an automated system for evaluating the test results are presented. Two statistical methods for classifying groups of samples and products according to measured values of E-T and E-NB, when sorting by grade (chemical composition) and heat treatment (hardness) of structural steels were investigated-cluster analysis and robust (stable) evaluations, which are suitable for data processing with high dispersion.
