The large-scale fire test specified in ASTM Standard E 2307 is used to evaluate a perimeter fire in a building. It is used to predict flame spread through a building's exterior but not via windows through a phenomenon known as leap frogging. This project developed computer-based tools to assist in the development of modifications to ASTM E 2307 to account for leap frogging. We used the Computational Fluid Dynamics model Fire Dynamics Simulator for this task. As a result of our work the ASTM task group modifying ASTM E 2307 will be able to look at the effect of test apparatus geometry modifications including spandrel height and window size, height and width, on the propensity for leap frogging.
