Ignition Test is to clip the fabric vertically, flame burns at the bottom, then observe if fabric debris occurs and the flame is extinguished itself before fabric burned out. The test aims to evaluate whether the fabric/materials is combustible.

Generally, this test is intended to determine the content of inorganic substances contained as impurities in an organic substance, and, occasionally, to determine the amount of inorganic substances contained as components in an organic substance.
