摘　　要：采用ISO 9705标准墙角火试验装置对2种火灾试验用标准燃烧物开展了定量试验研究。研究结果表明:控制瓦楞纸箱含水率和燃烧环境条件下,采用4角点火方式,2种内部蜂窝状结构的典型标准燃烧物热释放速率曲线均呈单峰分布,燃烧过程中无明显平稳燃烧段;塑料杯组合体、纸杯组合体标准燃烧物火灾荷载密度分布约600MJ/m2和200MJ/m2,单体燃烧火灾增长速率分别接近中速火和慢速火。In order to study the combustion characteristic of 2 kinds of standard combustion material, series of colorimetric experiments have been carried out using ISO 9705 standard cor her fire experimental device. And the research result shows that when the moisture content of corrugated box and combustion environment is under control, the heat release rate curves of the 2 standard combustion material both have the shape with single peak by ignited from 4 corners, and there is no obvious stable stage during the whole burning process. The fire load densities of plastic-cup and paper-cup standard commodities are 600 M J/ m2 and 200 MJ/m2 respectively, while their fire growth rates are close to medium fire and slow fire respectively.
