减少火灾烟气毒性危害最基础的工作离不开材料产烟毒性评价，然而试验方法的标准化工作进展缓慢。
The assessment of the fire effluent of the materials is the basic research item to reduce the toxicity to human beings, however, the standardization of the test method has got a very slow progress.
为了火灾全过程试验需要，以iso- 834标准降温曲线为参考对试验降温曲线进行控制。
The furnace heating can be controlled to make the average temperature in the furnace to follow as closely as possible the ISO-834 standard fire curve.
