“…Samples of intumescent compositions were tested by various methods, some of which are well-known, and the other developed in the framework of this study. The volume of charred layer (swelling coefficient) when applying IC samples to steel plates and their further heating was measured [11,12]; the coefficient of adhesion of the charred layer to the substrate was determined by the method of reverse strike, steel plates were also used as the substrate [13,14]; the kinetic parameters of ICs thermolysis were calculated by the methods of nonisothermal kinetics [10]. Also, two types of fire tests were carried out -in laboratory (smallscale fire tests) using the methodology developed by the authors; and large-scale fire tests, but also taking into account the innovations proposed by the authors.…”

“…When analyzing the literature, it was not possible to find references to indicative methods for assessing the characteristics of the charred layers, which are quite easily implemented in laboratory conditions, therefore, a previously developed installation that implements the method of reverse impact (Fig. 2) was used [13]. Columns (2) are fixed in the basis (1); sample (4) fixed in frame (3) can move up and down the columns.…”

The article observes the possibility and feasibility of introducing new and improved methodology for assessing the performance of fire retardant intumescent coatings for steel structures. The results of a comparative assessment of coatings based on a set of parameters obtained in laboratory conditions are presented: swelling coefficient, adhesion coefficient, adhesion of the coating system under high temperature conditions, kinetic parameters of thermolysis, thermal insulation. The smallscale laboratory test was developed to evaluate thermal insulating ability of 4 intumescent coatings applied to small steel plates. An improvement of the control method for assessing the fire retardant efficiency of intumescent coatings is proposed – instead of one test plate with dimensions of 600x600x5 mm with intumescent coating applied, a design of a metal frame-holder is proposed, in which 4 plates with dimensions of 300x300x5 mm can be fixed, and a set of thermocouples can be installed on each of them; all 4 plates are heated in the same conditions, thus the contradictions which may occur between the results of separate experiments are avoided. Such improvements made in the methodology of investigating the properties of intumescent coatings appeared to be fruitful, as correlation can be established between the laboratory tests and large-scale tests.

Coverage of modern views on security trends and directions for developing security systems in the context of global automation and integration into unified automated control systems. An overview of the prospects for using artificial intelligence in security systems to identify difficult to classify situations using signs obtained from monitoring data. Assessment of the prospects for the use of fire alarm systems based on the principles of artificial intelligence based on neural networks (building on the principles of combinatorics of methods of neural networks and odd logic systems). Construction of a mathematical model that describes the process of generating a reliable formation of a signal about the transition of the system to the "fire" state and a description of the problem of correctly setting the system response threshold for signal generation, solving the problem of minimizing the number of false positives by introducing an additional channel that receives initial information about the state of the object in the optical range. Investigation of the reliability of the characteristics of gas fire detectors declared by the manufacturer to determine the possibility of using them as initial elements of fire alarm systems built on the principles of neural networks.
