To date, there is no statistical base of critical values of surface heat flux density for various substances and materials, in particular those that can be used in the decoration of buildings and technological installations. This article presents conclusions from the analysis of recent studies on this issue, substantiates the reference tabular data of the dependence of wind on the critical surface heat flux density for corrugated cardboard using a full-factor experiment. The authors determined the largest and smallest indicators of significant factors influencing the value of the critical surface heat flux density, namely wind speed (v, m/s) and the set surface heat flux density (q, kW/m 2 ). In the course of the research, a mathematical model was constructed which describes the dependence of wind influence on the critical surface heat flux density for corrugated cardboard. These tables can be used in the future to develop an improved simplified method for predicting the thermal impact of fire on adjacent construction sites, taking into account the impact of wind.
