利用小尺寸轰燃实验台对松木和杉木的点燃性能进行了研究。该实验台能够提供接近实际火灾的燃烧环境，实验具有较好的可重复性。在锥形量热计实验的基础上提出了一种新的材料热辐射引燃判据。采用实验测得的轰燃实验台上层热烟气温度的平均值，结合热辐射引燃判据计算了木材在轰燃实验台中的点燃情况。

The ignition of both deal and fir blocks were tested with a bench-scale flashover test apparatus. Tests results showed that the bench-scale flashover test apparatus could offer a test environment similar to the true fire environment and tests executed with the apparatus had good repeatable property. Based on the cone calorimeter test results, a new ignition criterion of wood was presented in the paper. Ignition time of wood block in the bench-scale flashover test apparatus were calculated with the tested average temperature of the upper smoke layer and the new ignition criterion. The calculation results showed that the new approach was facile and available for the purpose of forecasting the ignition time of wood blocks in the bench-scale flashover test apparatus.
