• Abstract:
  A task group assembled under the auspices of the International Aircraft Materials Fire Test Working Group examined issues involving fire test approval of previously qualified interior material systems following renovation or alteration. A major problem associated with the alteration of interior system components is the difficulty in conducting certification tests that would determine if the altered interior component is still compliant with the heat release, smoke, and flammability certification requirements. In many instances, the appropriate substrates for conducting these follow-up certification tests are unavailable. As discussed in an earlier report, DOT/FAA/AR-TN95/83, International Aircraft Materials Fire Test Working Group, Material Systems Renovation and Repair Subgroup, the use of surrogate materials is the most feasible method for conducting certification tests following renovation, when samples of the actual buildup materials are unavailable. In order to validate the accuracy of using surrogate materials as heat release, smoke, and flammability predictors, tests were conducted in which several similar surrogate panels were compared. The surrogate panels were manufactured by three independent suppliers according to a common specification. Heat release and vertical Bunsen burner tests were conducted on the surrogate panels, which were finished with one of three paints or one of two laminates. The heat release test results indicate that each of the three surrogates reacts slightly different when tested without finish paint or laminate. When tested with a finished surface, the heat release results are even more scattered, providing evidence of the interrelationship between the substrate panels and the finish.
