An analysis methods using commercial software and experimental methods to evaluate the fire resistance of fire doors place an economic burden on customers. Therefore, in this paper, we developed a numerical computation procedure for predicting temperature rise in fire doors using convenient spreadsheet methods and finite difference methods. For the main parameters applied in the numerical calculation, the surface emissivity ε<sub>m</sub> = 0.30∼0.75 of EGI steel plate for fire door finishing materials was applied from a previous paper on emissivity determination. The thermal conductivity of mineral wool insulation was based on information provided by the manufacturer, and linear and exponential thermal conductivities were applied to enable application to high temperatures after 600 ℃. For the steel plate, the specific heat, density, and thermal conductivity recommended for carbon steel in Eurocode 3 were applied. The numerical calculation procedure of the developed spreadsheet method was verified for reliability and accuracy through comparison with fire test data, and therefore, it is judged that the developed spreadsheet method can be used when designing fire doors.
