Effect of Atmosphere Selection and Gravity Upon Flammability

A systematic study of the effects of atmospheric composition and gravity level upon the ignition and propagation of flame has been conducted to provide a better understanding of the phenomena of flammability. The principal purpose of this study was not to evaluate materials but to fill in gaps where information was required to help determine the relative effects of atmosphere composition, pressure level, ventilation rate, and gravity level on flame propagation rate and ignition phenomena. Common materials were selected to determine the effects of atmosphere and gravity on burning phenomena. This paper reports procedures and methods applied during the study, and presents the data obtained.
