Sources: R.L. q 158°-168° {\displaystyle t_{\text{ig}}} The values stated in SI units are to be regarded as standard. The temperature of the spark generated is normally higher than the ignition temperature of the conventional combustible materials (such as for sparks from steel, 1,400-1,500 °C; sparks from copper-nickel alloys, 300-400 °C); however, the ignition ability depends on the whole heat content and the lowest ignition energy of the material and substance to be ignited, respectively. The autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. Ignition Temperature . This temperature is required to supply the activation energy needed for combustion.The temperature at which a chemical ignites decreases as the pressure or oxygen concentration increases. ig As such, those plastic materials used in construction contain fire-retarding compounds to increase the temperature necessary before ignition and/or to lower the rate of burning.
