国外建筑外墙外保温系统防火性能评价方法与测试标准

Foreign evaluation method and test standard of building exterior insulation system

介绍美国、德国、英国、日本关于外墙外保温系统的防火性能试验方法以及材料燃烧性能分级的相关情况。可排水的薄抹灰式外墙外保温系统和干挂式外墙外保温系统已经发展为主要的体系。保温层临近部位总有一定的空气间隙,为防止烟囱效应,应至少每隔两层采用防火隔离带。各国都是将材料的燃烧性能检测与系统的大尺度燃烧测试相结合综合判定建筑外保温系统的防火性能。

The fire performance test methods of exterior insulation systems and classification for burning behavior of materials in the United States, Germany, Britain and Japan were intro duced briefly. Drainage thin plaster exterior insulation system and dry hanging exterior insulation system are major system now. The fire barrier should be set every 3 floors in gap of insulation layer to prevent the chimney effect. The fire perform ante of building exterior insulation system in those countries was tested by combining the combustion performance test and big size combustion test of materials.
