Pull-off testing according to DIN EN ISO 4624 Method B

With pull-off testing, the adhesive strength of a single- or multi-layer system can be determined quantitatively. In Method B, which is particularly suitable for rigid structures, a standardised die made of aluminum is glued to the surface and mechanically torn from the sample after the curing process of the adhesive. The force required for this is measured and normalised on the tested surface. The given results are the tensile stress, as well as a fracture pattern which provides insight whether it ruptured between two layers (adhesive fracture) or within a layer (cohesive fracture).
