The material spreadofflame along the surface of a product orientated in a vertical plane, is determined by this test method using the apparatus shown below.
材料的火焰沿着在定位在垂直面上的产品的表面传播，是由使用以下的实验装置的测试方法所确定的。
2
Effects of solid surface radiation heat losses on the flamespread characteristics are studied at different ambient oxygen concentrations and ambient pressures.
着重研究了表面辐射热损失、环境压力对火焰传播特性的影响。
