- Abstract
- A variety of tests have been proposed, and in some cases approved by technical societies, for measuring such diverse flammability properties of a material as ease of ignition, rate of heat release, rate of fuel and oxygen consumption, rate of smoke production, rate of toxic and corrosive gas production, and ease of extinction. Of concern here is the Steiner tunnel, in which the American Society of Testing and Materials test E84 is carried out, primarily to compare flame-spread characteristics of materials. While other measurements are made in the facility to characterize exothermicity, smoke obfuscation, and (possibly) toxicity of products, the most reproducible measurement within and between facilities is simple observation of how far "flame" progresses along a sample as a function of time during the ten-minute test.
