Abstract
Systematic investigations of the burning rate of fabrics in oxygen-enriched atmospheres reported upon earlier have been extended to include a series of measurements using each of the gases, helium, neon, and argon as the diluent gas for direct comparison with nitrogen. By setting and measuring flow rates, mass flow of each gas was ascertained. Analysis of the present data shows that while scorching occurs at the same exposure time irrespective of the gaseous composition and pressure, destruction rates are related to the simultaneous mass flow of both gases in the mixture. From these data it appears that the damping mechanism, believed from earlier observations to be a simple function of density, is influenced also by thermal conductivity and molecular constants.
