Abstract

The flash points and the fire points are one of the most important combustible properties used to determine the potential for the fire and explosion hazards of flammable substances. In this study, the flash points of aromatic hydrocarbons, were measured by using Pensky-Martens Closed Cup apparatus(ASTM-D93) and Tag Open-Cup apparatus(ASTM D 1310-86). Also the fire points of aromatic hydrocarbons, were measured by using Tag Open-Cup apparatus. The measured flash points were in good agreement with reference values. The measured fire points compared with the estimated values based on 1.23 times stoichiometric concentration. The values calculated by the proposed equation were in agreement with measured values.

인화점과 연소점은 가연성 물질의 화재 및 폭발 위험성을 결정하는데 가장 중요한 연소 특성치 가운데 하나이다. 본 연구에서는 방향족탄화수소에 대해 Pensky-Martens 밀폐식 장치(ASTM-D93) Tag 개방식장치(ASTM D1310-86)를 이용하여 인화점을 측정하였고, Tag 개방식 장치를 이용하여 연소점을 측정하였다. 측정된 인화점은 문헌값들과 일치하였으며, 연소점은 화학양론계수의 1.23배를 근거로 예측 값과 비교한 결과, 제시된 식은 실험값과 잘 일치하였다.
