Exploratory Studies of Heat Transfer and Burning Behavior of Films and Fabrics.
A F. Robertson
A report of preliminary-exploratory studies is pre sented of the heat transfer dosage likely to be received by a substrate when exposed to burning plastics and textiles. Two spacing positions of specimen and substrate were investigate 5/16 in. and 1 in. Four different positions with respect to horizontal orientation of the specimen were explored and seven different specimen materials were tested. The results suggest that single drips from a polyethylene film will provide sufficient thermal dosage to cause third degree burns. There is evidence that for the closer spacing the major portion of the thermal dosage takes place through gas and vapor convection and condensation. At the larger spacing radiation plays an important heat transfer role and may account for as much as 40 to 50% of the thermal dosage. It is shown that light fabrics, may when burned, result in disproportionally large (on a weight basis) thermal dosage. Date 1972?
