Abstract

The aim of this study is to predict the ignition times and the HRR(heat release rate) for building interior materials. By using the literature data and RSM(response surface methodology), the new equations for predicting the ignition time and the HRR of building interior materials are proposed. The A.A.P.E.(average absolute percent error) and the A.A.D.(average absolute deviation) of the reported and the calculated ignition times by means of the thickness and the density were 4.35 sec and 1.57 sec, and the correlation coefficient was 0.987. The correlation coefficient of the reported and the calculated the net HRR by means of burner width and power was 0.983. Also the correlation coefficient of the reported and the calculated the total HHR by means of burner width and power was 0.999. The correlation coefficient of the reported and the calculated the maximum flame height by means of burner width and power was 0.999. The values calculated by the proposed equations were in good agreement with the literature data.

본 연구의 목적은 건축내장재의 발화시간과 열방출율을 예측하고자 한다. 반응표면방법론(RSM)과 문헌자료를 사용하여 건축내장제의 새로운 발화시간과 열방출율의 예측식을 제시하였다. 재료의 두께와 밀도에 의한 발화시간의 예측값과 문헌값의 A.A.P.E.는 4.35초, A.A.D.는 1.57초 그리고 상관계수는 0.987이였다. 버너의 폭과 열량에 의한 순열방출율의 예측값과 문헌값의 상관계수는 0.983이였으며, 버너의 폭과 열량에 의한 총열방출율의 예측값과 문헌값의 상관계수는 0.999였다. 또한 버너의 폭과 열량에 의한 최대 화염높이의 상관계수는 0.999로서, 제시한 예측식들에 의한 예측값은 문헌값과 일치하였다.
