A method for testing the adhesion of elastic adhesives or elastic sealing materials on surfaces of components including: a) applying the adhesive/sealing material to a component surface, b) attempting by exerting a peeling force to detach the applied adhesive/sealing material from the component surface, and c) assessing the adhesion of the adhesive/sealing material on the basis of fractures caused in the adhesive/sealing material and the detachment of the adhesive/sealing material from the component surface by the exertion of the peeling force. Prior to and/or during step a), an anti-adhesion material layer is applied to at least one first part of the component surface, which causes poorer adhesion of the adhesive/sealing material to the component surface and therefore can be detached from the component surface with less peeling force than directly from the component surface.
