The blister test is used to determine the interfacial fracture energy (IFE) of hot-poured crack sealant at the application temperatures. The blister test is a test of fracture. The object of the test is to apply tensile forces using hydrostatic pressure at the interface between sealant and aluminum. Sealant is molded on top of an aluminum disk. The applied hydrostatic pressure and displacement can be recorded as functions of time. Interfacial fracture energy required to break the bond can be calculated using the loaddisplacement curve through the fracture energy concept. This energy can be considered a measure of bonding. This standard does not purport to address all of the safety concerns@ if any@ associated with its use. It is the responsibility of the user of this standard to establish and follow appropriate health and safety practices and to determine the applicability of regulatory limitations prior to use.
