ASTM E 108 是针对建筑屋顶覆盖物的阻燃性能测试,要申请该测试,首先要先确定要执行的级别,级别分类不同,样品规格跟测试方法不同。
ASTM E108 阻燃测试- 标准全称:
ASTM E108 Standard Test Methods for Fire Tests of Roof Coverings
ASTM E108屋顶覆盖物防火试验标准试验方法
三个级别分类的火灾试验适用范围:
A级试验适用于以下屋顶覆盖物:预计可有效抵御严重火灾,为屋顶甲板提供高度防火保护,不会从位置滑落,预计不会造成飞火危险。
B级试验适用于预期能有效抵抗中度火灾暴露、对屋顶甲板提供中度防火保护、不会从位置滑落且不会造成飞火危险的屋顶覆盖物。
C级试验适用于能够有效抵御轻度火灾、为屋顶甲板提供轻度防火保护、不会从位置滑落且预计不会造成飞火危险的屋顶覆盖物。
因为三个级别测试方法跟适用范围不同,所以测试前需要确认要申请的级别。
ASTM E108 阻燃测试- 标准范围:
本防火测试标准主要是测量暴露于建筑物外部在模拟火源下的屋顶覆盖物的相对防火特性它适用于用于安装在可燃或不可燃屋顶甲板上的屋顶覆盖物。
