An Investigation of the FAA Vertical Bunsen Burner Flammability Test Method.
Abstract:
The vertical Bunsen burner test method, as specified in appendix F of the Federal Aviation Regulations-Part 25, was evaluated in order to update and clarify certain problem areas. Burner fuel, flame temperature and flame placement were investigated. It was determined that 1 methane gas can be used as a replacement or alternative to B-gas, 2 a minimum flame temperature specification is meaningless without specifying thermocouple wire thickness, and 3 placing the flame at the midpoint of the lower edge of the front face results in a more realistic and severe evaluation of the specimens flammability properties.
