Abstract
Abstract A pervious study has reported effects of spacing on vertical burning of thin PMMA. However, one and two face burning of PMMA is not considered. The present study has revisited this topic by performing experiment using 300 mm height, 50 mm width, and 2 mm thickness PMMA sheets with one and two face burning cases. The steady state heat balance theory of one and two face burning is proposed. The flame height, pyrolysis height, and burnout length were measured by video image analysis. The results show that the values of flame height, pyrolysis height, and burnout length for two face burning are 1.4 times that of one face burning. The relationships between flame height and pyrolysis height, as well as flame spread rate and effective heating length are analyzed.
