用小规模试验数据预测全尺寸火灾试验结果

在消防界，很多人都想用小规模试验数据来预测全尺寸火灾试验的最终结果。为了通过模拟平行板试验的中等规模试验来达到这个目的，并且把试验结果与FM认可的25ft墙脚火试验（ANSIFM4880）的结果进行比较。利用从实验室试验得来的数据开发了一个模型，用来预测燃烧平行板材所获得的全部热释放速率。对于不同的板材，平行板材下面的沙盘燃烧器释放的速率也随之不同。比较结果非常不错。但是，同25ft墙脚试验的比较显示，通过修正空间和燃烧器大小可以获得与平行板材构造更佳的相关性。

From bench-scale test data to predictors of full-scale fire test results

There is a strong desire in the fire safety community for methods that use bench-scale test data to predict the final outcome of full-scale fire tests. The current project has the objective of meeting this goal through modeling an intermediate-scale test called the parallel panel test and comparing the results of the test with FM Approvals 25 ft Corner Test (ANSI FM 4880). The Corner Test has been used to evaluate the fire hazard of insulated wall and plastic interior/exterior building panels. As the first step of the project, a model predicting the total heat release rates from the burning parallel panel tests using the data obtained by the bench-scale tests was developed. The heat release rates of the sand burner at the bottom of the parallel panels were varied during the tests for each different panel material. The results of the comparison were very favorable. However, comparisons with the 25 ft Corner Tests indicate that an improved correlation with the parallel panel configuration could be obtained by a modification of the space and the burner size.
