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