Abstract

The project aimed to develop a reduced scale test protocol designed to be repeatable and capable of providing the upward fire evaluation for assessing fire risk on external thermal insulation composite system facade samples. The variation of heat flux is simulated by radiant panel. This experimental setup permits the recording of dynamic variables in flame propagation, such as ignition time, flame extinguishing time, and variations in both surface and back temperatures of the insulation panel. Notably, the measurement of back temperature provides a means to assess the thermal insulation efficiency of the external thermal insulation composite system facade. Furthermore, the fire spreading temperature is collected during the test could also be useful for larger-scale testing.

用于研究火焰上升热量对外墙外保温复合系统影响的缩小比例试验台

该项目旨在开发一种规模较小的测试协议，其设计具有可重复性，能够为评估外墙外保温复合系统样品的火灾风险提供向上的火灾评估。热通量的变化由辐射板模拟。这种实验装置可记录火焰传播过程中的动态变量，如点火时间、火焰熄灭时间以及隔热板表面和背面温度的变化。值得注意的是，背面温度的测量为评估外墙外保温复合系统的隔热效率提供了一种方法。此外，在测试过程中收集的火灾蔓延温度也可用于更大规模的测试。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
