- Abstract
- A small laboratory size experiment was used to observe the characteristics of flame spread over various carpets under various constant external radiant fluxes. The results indicate that a minimum radiant flux is necessary to sustain flame spread over a carpet surface for the carpets tested. By increasing radiant flux, the flame spread velocity increases sharply and can reach several cm/sec. At a high external radiant flux, preheating time is the controlling factor for flame spread velocity, ignitability, weight loss, and net heat release rate were also measured under various radiant fluxes. The effect of an underlayment on ignitability, flame spread speed, weight loss, and net heat release rate, was also observed for various carpets.
