ASTM E108 Standard Test Methods for Fire Tests of Roof Coverings
ASTM E108 屋顶覆盖物的防火试验的标准试验方法

ASTM E108屋顶材料防火试验标准－适用范围
1.1 This fire-test-response standard covers the measurement of the relative fire characteristics of roof coverings under simulated fire originating outside the building. It is applicable to roof coverings intended for installation on either combustible or noncombustible decks when applied as intended for use. The following test methods are included:
1.1.1 Intermittent flame exposure test.
1.1.2 Spread of flame test.
1.1.3 Burning brand test.
1.1.4 Flying brand test.
1.1.5 Rain test.

ASTM E108屋顶材料防火试验－防火等级 Class A/Class B/Class C
1.2.1 Class A Tests are applicable to roof coverings that are effective against severe test exposure, afford a high degree of fire protection to the roof deck, do not slip from position, and do not present a flying brand hazard.
1.2.2 Class B Tests are applicable to roof coverings that are effective against moderate test exposure, afford a moderate degree of fire protection to the roof deck, do not slip from position, and do not present a flying brand hazard.
1.2.3 Class C Tests are applicable to roof coverings that are effective against light test exposure, afford a light degree of fire protection to the roof deck, do not slip from position, and do not present a flying brand hazard.
