The fire point of a fuel is the temperature at which it will continue to burn for at least 5 seconds after ignition by an open flame. At the flash point, a lower temperature, a substance will ignite briefly, but vapor might not be produced at a rate to sustain the fire. Most tables of material properties will only list material flash points, but in general the fire points can be assumed to be about 10 °C higher than the flash points. However, this is no substitute for testing if the fire point is safety critical.
Famous quotes containing the words fire and/or point:
“All praise of the hawk on fire in hawk-eyed dusk be sung,
When his viperish fuse hangs looped with flames under the brand
Wing, and blest shall
Young
Green chickens of the bay and bushes cluck, “dilly dilly,
Come let us die.””
—Dylan Thomas (1914–1953)
“Ideals possess the strange quality that if they were completely realized they would turn into nonsense. One could easily follow a commandment such as “Thou shalt not kill” to the point of dying of starvation; and I might establish the formula that for the proper functioning of the mesh of our ideals, as in the case of a strainer, the holes are just as important as the mesh.”
—Robert Musil (1880–1942)
