纤维素火点火后有缓慢的火焰温度上升.。标准的纤维素火灾温度与时间曲线应是参考文献:bs476,imo决议a517(13),iso r834和国际海上人命安全公约。典型的辐射值5分钟后点火为50千瓦/平方米。4.10 在校准实验中火环境应满足3.1条款要求,校准实验的时间应为60分钟.
纤维素火灾温度与时间曲线的美国(astm e119,nfpa251,ul263)稍快。
hydrocarbon firethermocouples located at each of four levels (minimum of 12 thermocouples). the upper and lower levels are to be 2 ft (610 mm) from the ends of the steel column, and the other two intermediate levels are to be equally spaced between the upper and lower levels. the thermocouples at each level are to be placed to measure significant temperatures of the
烃类火灾a hydrocarbon fire has a rapid flame temperature rise after ignition. the standard hydrocarbon fire碳氢化合物火灾燃烧后火焰温度迅速上升。标准烃火 temperature vs. time
温度与时间曲线应是bs476 20和ul1709。典型的稳态温度为1100 oc。curve shall be that of bs476 part 20 and ul1709. typical steady-state temperature is 1100 oc.
typical radiation value 5 minutes after ignition is 160 kw/m2.
典型的辐射值5分钟后点火为160千瓦/平方米。喷射火 jet fire
jet fire is a turbulent diffusing flame, resulting from the combustion of a steady release of pressurised liquid
喷火是湍流扩散火焰,一个稳定的释放加压液体燃烧产生的
