Abstract
Autoignition characteristic is an important factor of all combustible substances, and a critical determinant in assessing the effectiveness of fire hazard prevention. This study investigated the autoignition characteristic of mixtures of Ethylene Glycol and water using an ASTM D2155 type ignition temperature measuring apparatus. It was possible to get the minimum temperature as $\small{434^{\circ}C}$ from 100% Ethylene Glycol within range of $\small{75{\sim}160{\mu}l}$. A volume of $\small{100{\sim}125{\mu}l}$ of a mixed sample of Ethylene Glycol and water (80 : 20) was ignited at the same temperature ($\small{434^{\circ}C}$). Also it was possible to get the auto ignition temperature as $\small{437^{\circ}C}$ from a mixed sample of Ethylene Glycol and water (60 : 40) within range of $\small{120{\sim}160{\mu}l}$. The instantaneous ignition temperatures determined for $\small{125{\mu}l}$ of each of the three samples were $\small{579^{\circ}C}$, $\small{595^{\circ}C}$ and $\small{611^{\circ}C}$, respectively. Both auto ignition temperatures and instantaneous ignition temperatures were increased through the addition of water to the samples.
