Abstract
In recent years, the Aminco-NBS smoke density chamber (ASTM Method E 662) has been frequently used for measuring the smoke yield of materials. If chamber data could be related to larger scale fire experiments, the test method would contribute to cost-effective fire research. In this study, a specially modified chamber facilitated smoke sampling at several locations. Sampling at various locations established the smoke distribu tion and made it possible to calculate correlating parameters using 3/8-inch (0.953 cm) thick Douglas-fir plywood. In general, the particulate optical density (POD), the mass optical density (MOD), and the weight fraction (χ) of par ticulates in the smoke showed considerable variability. Particulate mass concen tration could be the most important predictive variable.
