노말언데칸의 안전한 취급을 위해서 하부인화점, 상부인화점, 연소점 그리고 발화지연시간에 의한 발화온도를 측정하였다. 또한 노말언데칸의 하부와 상부인화점의 측정값을 이용하여 폭발하한계와 상한계를 예측하였다. 밀폐식 장치에 의한 노말언데칸의 하부인화점은 $59^{circ}C$와 $67^{circ}C$로 측정되었고, 개방식 장치에 의한 하부인화점은 $67^{circ}C$와 $72^{circ}C$로 측정되었다. 클리브랜브 장치에 의한 노말언데칸의 연소점은 $74^{circ}C$로 측정되었다. ASTM E659-78 장치를 사용하여 자연발화 온도와 발화지연시간을 측정하였고, 여기서 측정된 최소자연발화온도는 $198^{circ}C$였다. 측정된 하부인화점 $59^{circ}C$와 상부인화점 $83^{circ}C$를 이용하여 예측된 폭발하한계는 0.65 Vol.%, 폭발상한계는 2.12 Vol.%였다.
For the safe handling of n-undecane, the lower flash points and the upper flash point, fire point, AITs (auto-ignition temperatures) by ignition delay time were experimented. Also lower and upper explosion limits by using measured the lower and upper flash points for n-undecane were calculated. The lower flash points of n-undecane by using closed-cup tester were measured $59^{circ}C$ and $67^{circ}C$. The lower flash points of n-undecane by using open cup tester were measured $67^{circ}C$ and $72^{circ}C$, respectively. The fire point of n-undecane by using Cleveland open cup tester was measured $74^{circ}C$. This study measured relationship between the AITs and the ignition delay times by using ASTM E659 apparatus for n-undecane. The experimental AIT of n-undecane was $198^{circ}C$. The estimated lower and upper explosion limit by using measured lower flash point $59^{circ}C$ and upper flash point $83^{circ}C$ for n-undecane were 0.65 Vol.% and 2.12 Vol.%.
