Standards Include:
ASTM E 108
NFPA 256
UBC 15-2
UL 790
This test standard examines the performance of roof-covering materials when
exposed to fire originating from sources outside a building on which the
coverings may be installed. It is applicable to roof coverings intended for
installation on either combustible or noncombustible decks when the roof
coverings are applied as intended. The following test methods are included in
this standard: the intermittent flame exposure test, the spread of flame test,
the burning brand test, the flying brand test, and the rain test.
Three classes of fire test exposure are described in this standard.
Class A roofing assemblies are effective against severe fire test exposures.
Under such exposures, roofing assemblies of this class are not readily
flammable, afford a fairly high degree of fire protection to the roof deck, do
not slip from position, and are expected not to produce flying brands. Class B
roofing assemblies are held to the same standards as Class A, but are exposed
to moderate flame, Class C roofing assemblies are exposed to light flame.

Standards Include:
ASTM D 2898
UBC AC-107
These test methods cover the durability of a fire-retardant treatment of wood under exposure to accelerated weathering. It is intended that fire-retardant treatment of the specimen be by pressure impregnation, rather than being simply by a surface coating with or without a protective layer. Two conditioning methods are described, both suitable for application to a test specimen prior to subjecting that specimen to an appropriate fire test. These methods are applicable to treated wood products or assemblies thereof. The test specimens will be in the form of, or suitable for fabrication into, fire test specimens, such as those described in Test Methods E 84, E 108, and E 286.
