Abstract:

A method and criterion are described to assess the no-effect level of a constituent change on the fire performance of aircraft cabin material or construction. A constituent may be a thermosetting resin, coating, composite, adhesive, potting compound, film, fabric, elastomer, rubber, or thermoplastic. This can be used in the construction of a cabin material whose heat of combustion can be reliably measured using a 1-10 milligram sample in American Society for Testing and Materials (ASTM) D7309-21, Standard Test Method for Determining Flammability Characteristics of Plastics and Other Solid Materials Using an MCC. Bench-scale fire testing as per 14 Code of Federal Regulations (CFR) § 25.853 (Compartment Interiors, 2020) was conducted on several dozen cabin materials with changed constituents. Results showed that the relative difference in the microscale Fire Growth Capacity (FGC) of the certified and changed constituent in ASTM D7309-21 must be less than 0.3 (30%) to have no significant effect on the fire performance of the cabin material.
