The '''limiting oxygen index (LOI)''' is the minimum concentration of [[oxygen]], expressed as a percentage, that will support [[combustion]] of thea [[polymer]]. It is measured by passing a mixture of O₂oxygen and [[Nitrogen|N₂nitrogen]] over a burning specimen, and reducing the O₂oxygen level until a critical level is reached. <ref>Definition taken from Principles of Polymer Engineering (2nd edition) by N.G.
