- Abstract
- Experiments were conducted to determine the cause of anomalous results in vertical flammability testing. Some fabrics of marginal flammability had indicated an increased tendency to support flame propagation when the time of exposure to the test flame was decreased. The severity of the vertical test procedure was found to be a maximum when the burner was applied for only the interval necessary for ignition of the sample. With a longer application of the burner to fabrics of marginal flammability, the burning of the fabric may be extinguished by the less-than-ambient oxygen content of the burner plume.
