Investigation of the FAA (Federal Aviation Administration) Vertical Bunsen Burner Flammability Test Method

摘要

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 specimen's flammability properties.
