Abstract:

A physically based microscale combustion parameter for early stage fire growth, called the fire growth capacity (FGC) (J/g-K), is derived from a simple burning model. The FGC combines the ignitability and heat release of the material into a single parameter that can be measured in a microscale combustion calorimeter (MCC) using the standard ASTM D7309 method. The FGC measured at microscale (10-6 kg) in the MCC successfully ranks commercial materials according to their behavior in bench (kg) scale flame (UL 94 V) and fire (14 CFR 25) tests. For this reason, FGC is being evaluated by an aviation industry working group as an alternate means of complying with Federal Aviation Administration fire performance requirements of cabin materials in transport category aircraft when a small component of a certified cabin material must be changed due to cost, availability, performance or environmental concerns. The intent of this report is to validate the proposed methodology and criteria for comparing the components of aircraft cabin materials with respect to flammability. Results for twelve industry case studies were collected and analyzed. In 95% of the cases, the proposed similarity criteria successfully detects a significant change in 14 CFR 25 fire test performance of two materials.
