Anotácia

Description / Abstract: This document specifies a method for the rapid permeation of water to an adhesive layer using a specimen with one side open, the secondary bonding of the specimens with the adhesive layer that is still moistened, and a shear strength test of the secondary bonded specimen, for the selection of water-resistant adhesives and the determination of suitable surface treatments. It does not assess the water resistance of the actual joint itself, as the distribution of water in the adhesive layer is different. This test procedure does not provide design information.
