Thermally thin material is more easily ignited than thermally thick material does in the initial stage of fire disaster, so studying the ignition models of thermally thin material has important significance to preventing fire. Cone calorimeter （CONE） was used to test the ignited time of copy papers in different heat fluxes. And the tested ignited time was contrasted with that computered by the theoretical models. The ignition model of linear processing heat loss was well consistent with the test result,which can provide the calculating formul...
