摘要
用两种不同的实验方法系统地研究了三种常用的聚氯乙烯装饰材料的着火特性，探讨了不同的辐射热通量对其着火时间的影响．若用１／ｔｉｇ 对辐射热通量作图，则可得到最小辐射热通量，并且两种实验方法所得到的实验结果具有较好的相关性．
The ignition characteristics of three commercially available PVC materials, i.e. PVC floor coverings, tiles and sheets were tested using an ignition apparatus and the Cone Calorimeter at different heat fluxes. Some correlation is found between the two methods. The minimum heat flux for piloted ignition for the PVC materials has been obtained through the extrapolation of the plot of 1t ig vs. heat flux.
