4.1 This test method is used to determine the dimensional changes and physical stability of the product upon exposure to specified cyclic thermal conditions. It is also useful in determining the integrity of the bond between the metal foil and the SBS-modified bituminous compound.
1.1 This test method covers the measurement of movement due to cyclic thermal exposure of SBS (styrene-butadiene-styrene)-modified bituminous sheets with a factory-applied metal foil surface.
