Combustibility and flammability - Wikipedia

WebThe upward flammability limiting oxygen indices (ULOIs) were calculated with the “up-and-down method for small samples” [9]. This method has been adopted by both ISO 4589 [10] and ASTM D 2863 for determining the “minimum oxygen concentration required to support combustion of plastics” [8]. WebThe purpose of the Limiting Oxygen Index (LOI) test, sometimes referred to as Oxygen Index (OI) or Critical Oxygen index (COI), is to measure the relative flammability of plastics and composite materials by burning them in a controlled atmosphere consisting of a mixture of oxygen and nitrogen.

The higher limit rose from 65 percent hydrogen in air to 81 percent in a 40-percent oxygen mix-ture, 86 percent in a 56-percent oxygen mixture, and 91.6 percent in nearly pure oxygen (323). In a mixture of equal volumes of oxygen and nitrogen, 91.35 percent hydrogen inflamed at 5370 C. (216).

WebOxygen is not flammable, though it acts as an oxidizer and can intensify fires. There is more oxygen in an ozone molecule than there is in a standard oxygen molecule, and this can mean it burns even more intensely than standard oxygen. WebFlammability limits also depend on the type of atmosphere (for example, limits are much wider in oxygen than in air), the pressure, and the temperature of atmosphere. Explosion limits usually refer to the range of pressure and temperature for which an explosive reaction at a fixed composition mixture is possible.
