“…However, there is the problem of choosing criteria for ordinary specialist who decide on the technical condition of objects. The research in this area [1][2][3] show that a reliable estimate of the results according to AE data registration has a certain probability and requires the development of valid algorithms for the selection of criteria the state of objects.…”

This work presents the analysis of damage assessment for dangerous industrial objects of acoustic emission method. Samples of low carbon and low alloy steels were researched. The aim of this work is to experimentally determine damage assessment for the state of developed and unacceptable sources of acoustic emission. Cracks of various lengths have been obtained by low-cycle loading. According to research, it is necessary to use several criteria simultaneously to increase the reliability of inspection of each growing crack.
