Defined autoignition temperature ( T ) flooring (NP) based on polyvinyl two brands at heating rates of 5, 10, 15, 20, 25 degrees per minute in an air atmosphere. A new approach to the methodology for determining T heat and mass transfer as an input parameter in the construction of a mathematical model of thermal destruction, that allows to control the process. The process of thermal decomposition of the NP in the air is considered from positions of system analysis. In this regard, the thermal decomposition process is a complex physical-chemical system, having a hierarchical structure. A significant element in this system is to determine the critical parameters of the system - in this case, related to the process of self-ignition. In the vicinity of T .functional link between the generalized criteria is based on the similarity of the conditions of the integral heat and mass transfer processes in fire conditions. Dependencies of T from the heating rate are relaxing nature, which allows to define T at high heating rates in fire conditions. Statistical analysis of the data to determine T have been carried out at a significance level of 0,05 and fiducial probability P = 0,95.
