ASTM E84美标表面燃烧测试-等级分类:
高层建筑和楼道,要求FSI<25,FSI=25-100的材料只能用于防火要求不高的场所,FSI>100的材料不符合阻燃要求。ASTM E84将实验测得的Flame Spread Index (FSI值)和烟雾密度将材料防火等级分成三个等级:A级为0-25;B级为26-75 ;C级76-200,烟指数小于450。

ASTM E84美标表面燃烧测试-英文标准简介:
ASTM E84 fire-test-response standard for the comparative surface burning behavior of building materials is applicable to exposed surfaces such as walls and ceilings. The test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source. The material, product, or assembly shall be capable of being mounted in the test position during the test. Thus, the specimen shall either be self-supporting by its own structural quality, held in place by added supports along the test surface,or secured from the back side.
