Metals Flammability: Review and Model Analysis

Source

With its founding in 1975, ASTM Committee G-4 embarked on the process of defining the concept of the flammability of metallic materials in oxygen-enriched atmospheres. While joined in this process by the National Aeronautics and Space Administration, the National Fire Protection Association, and the Compressed Gas Association, there is yet no explicit definition. However, it is clear that the postignition concept of flammability equates to combustion propagation, synonymous with steady-state burning under specified conditions. In this paper, four models are developed under specified environmental conditions that characterize flammability. Three incorporate the system-independent properties of heat of combustion, burn ratio, thermal conductivity, and flame temperature; four involve the system-dependent properties of promoted combustion, threshold pressure, oxygen index, and burn rate. A model solution, therefore, provides a measure of flammability.
