The Federal Aviation Administration Standard 2-gallonhour burner was adapted to measure the burn-through resistance of aircraft cargo compartment lining materials. This laboratory test can subject lining samples to the fire conditions found in full-scale class D cargo compartment tests. A 5-minute test period is of adequate duration to evaluate the performance of cargo lining materials, based on full-scale test results which showed that class D fire intensity is reduced to a smoldering state after several minutes. It was determined that the 2-gallonhour burner test is superior to the vertical and 45 deg bunsen burner tests specified in Federal Air Regulations FARs 25.853 and 25.855 for evaluating the flammability and burn-through resistance of cargo compartment lining materials. The following criteria for class D cargo compartment lining materials using the 2-gallonhour burner test are proposed Sample must prevent burn-through for 5 minutes, and peak temperatures at 4 inches above the upper surface of a horizontal test sample should not exceed 400 deg Fahrenheit. Based on results with this laboratory test, it is concluded that fiberglass lining materials provide sufficient protection to prevent burn-through in a class D cargo compartment fire however, Nomex and Kevlar lining materials will not contain a class D cargo compartment fire.
