- Abstract
- Flame spread over carpet surfaces was studied under various constant external radiant fluxes from 0.4 to 1.2 W/cm(2). Characteristics of ignition and flame spread including speed of spread and net heat release rate were mesured. The results indicate that these values increase rapidly with increasing external radiant flux. it was also observed that there exists a minimum radiant flux necessary to sustain steady flame spread for each carpet. The underlayment of a carpet has a significant effect on ignition and flame spread speed for nylon carpets due to melting of fibers before flameover. However, this effect is negligible for low pile density acrylic carpets.
