Abstract
A test for the ease of ignition of interior finish materials by flame exposure was developed. Two specimens, 140 mm wide by 152 mm high, face each other at a distance of 53 mm apart. A methane diffusion flame burns between these surfaces and extends to about 152 mm above them. The operator observes the specimen surface and records the time to flame attachment. A phototube, which views the exposure flame, shows a marked increase in output when the specimens start contributing fuel. The ignition sensitivity is expressed by the time to flame attachment and by the time to fuel contribution. The times to flame attachment measured in the ignition apparatus generally ranked 22 materials with the observed times of wall involvement in full-scale tests. The results of this test may be usefel as one factor in computer models of fire growth in enclosures.
