Abstract
A method for determining flame retardance of polymer compositions includes subjecting a plurality of specimens of a polymer composition to a flame test and performing a statistical analysis of the data obtained. The statistical analysis includes determining the probability of at least one possible outcome of the flame test. The probability of possible outcomes provides a measure of the flame retardance of the polymer composition. A preferred flame test is the UL-94 flame test.
