ASTM E108  Standard Test Methods for Fire Tests of Roof Coverings

Standard Scope:

1.1 This fire-test-response standard covers the measurement

of the relative fire characteristics of roof coverings exposed to

simulated fire sources originating outside the building. It is

applicable to roof coverings intended for installation on either

combustible or noncombustible roof 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.

Three classes of fire test exposure are described:

1.2.1 Class A Tests are applicable to roof coverings that are expected to be effective against severe fire exposure, afford a high degree of fire protection to the roof deck, do not slip from position, and are not expected to present a flying brand hazard.

1.2.2 Class B Tests are applicable to roof coverings that are expected to be effective against moderate fire exposure, afford a moderate degree of fire protection to the roof deck, do not slip from position, and are not expected to present a flying brand hazard.

1.2.3 Class C Tests are applicable to roof coverings that are effective against light fire exposure, afford a light degree of fire protection to the roof deck, do not slip from position, and are not expected to present a flying brand hazard.
