Thermoplastic Expanded Polystyrene (EPS) External Thermal Insulation Composite Systems (ETICS) has caused serious results due to the ravages of frequent fire disasters. The fire propagation over EPS ETICS surface was observed to be very fast. High temperature threatens the safety of exterior building wall. However, vertical temperature distribution of EPS ETICS façade fire (without cavity) is not available until now. Presently, a quantitative correlation was investigated through a series of theory derivation and experiment tests, which involves vertical temperature distribution of EPS ETICS façade surface, window fire intensity, thermal parameters and fire propagation potentials of EPS ETICS specimen. The theory consists of three parts, window-spilled fire model, thermal parameters and fire propagation index (FPI) method. In JIS A 1310 standard tests, widow fire intensity changes from 600 to 1100 kW, thermal response parameter differs from 163.9 to 276.8 kW · s²/m² and FPI varied from 17.1 to 28.9 (m/s^1/2)/(kW/m)^2/3. Finally, an adequate approximation for vertical temperature in the form of a dimensionless temperature is proposed based on test results. It provides a potential correlation to obtain vertical temperature distribution prior to the intermediate-scale test.

基于JIS A 1310方法的EPS外保温复合系统砌体外墙火灾垂直温度分布试验研究

热塑性发泡聚苯乙烯 (EPS) 外保温复合系统 (ETICS) 由于频繁的火灾灾害造成严重后果。观察到在 EPS ETICS 表面上的火蔓延非常快。高温威胁着建筑外墙的安全。但是，EPS ETICS 立面火灾（无空腔）的垂直温度分布直到现在还没有。目前，通过一系列理论推导和实验测试，研究了EPS ETICS立面垂直温度分布、窗户火灾强度、热参数和EPS ETICS试件火灾蔓延潜力的定量相关性。该理论由漏窗火灾模型、热参数和火灾传播指数(FPI)方法三部分组成。² /m ²和FPI从17.1变化到28.9(m/s ^1/2 )/(kW/m) ^2/3。最后，基于测试结果提出了以无量纲温度形式对垂直温度进行充分近似的方法。它提供了一个潜在的相关性，以在中间规模测试之前获得垂直温度分布。
