Title: HOW TO ENGINEER A MATERIAL FIRE TEST
Abstract:
A fire test protocol is developed from engineering principles and standard material properties for measuring the thermal fire hazard of a ceiling material in hardened military vehicles. This presentation offers a new approach to flammability test development from the past ad hoc ranking performance in countless material fire tests. Pass/Fail criteria are cast in formulas involving critical heat flux (CHF), heat release parameter (HRP), thermal response parameter (TRP) and available energy parameter (AEP) – fire properties that can be measured in standard tests. The pass/fail criteria are based on the fire hazard identified in this particular vehicle fire scenario. For this case the pass/fail criteria become CHF > 25 kW/m2 or TRP > 274 kW-s1/2/m2, or HRP < 140 kW/m2/(30 kW/m2 - CHF) or AEP < TRP2(30-CHF)HRP/900. Materials test results are consistent with these criteria.
