The result shows that the requirements and testing methods for flammability of building materials are similar between the United State and Canada, and they mainly are engaged in the test of combustibility and flame spread. In European Union, a new classification system for flammability of building materials was implemented in 2001, which includes two systems; one is for floor coverings and the other for all other building units. In Japan, the interior materials are classified into non-combustible, quasi noncombustible and fire-retardant materials according to Cone Calorimeter method (ISO 5660). China has established a non-combustible test, a three-class classification system for combustible wall and ceiling interior finishing materials and a two-class classification system for combustible floor coverings.

通过研究认为：美国和加拿大对建筑材料燃烧性能的要求和试验方法基本相似，他们主要针对材料的燃烧性、火焰传播进行检测；欧盟于2001年颁布了新的燃烧性分级体系，该分级体系包括专门针对铺地材料部分和针对其他所有建筑构件材料和产品部门；日本采用锥形量热计法(ISO 5660)将内装饰材料分为不燃、准不燃和阻燃材料3个等级；我国对建筑材料的试验方法包括不燃性试验方法、墙和天花板内装饰材料的三级分级体系和铺地材料两级分级体系。
