In the paper the analysis of electrochemical current noise obtained during stress corrosion of stainless steel specimen is presented. In the contrast to the traditional approach the condition of stationarity of the records obtained is not obeyed. The changes of electrochemical properties of analysed systems are manifested in temporal variations of corresponding noise response. Thus the modification of spectral noise response is made to make this value time-dependent. Such approach can be understood as the complementary to the impedance analysis of stress corrosion phenomenon.
