The fire factor determined in the C9 thermal test is 0.32, a value larger than the value of 0.14 determined in the C6 thermal test. This implies that the foam released more energy in the C9 test which may be a consequence of the higher temperature reached by the polyurethane foam layer due to the higher shroud temperature. 19
