Abstract: The invention relates to a method and device for testing the adhesion of an adhesive, planar body on a planar substrate, wherein the planar body is applied adhesively on the substrate, the substrate is moistened, and a mechanical force is exerted on the substrate by means of an element in the form of a dumbbell-shaped magnetic stirring rod acting on the side of the substrate facing away from the adhesively applied body, wherein the substrate is repeatedly reversibly deformed at least in parts of the adhesive region of the planar body by means of the exertion of force, and, after a period of time, exertion of the mechanical force is ended, and the remaining adhesion of the planar body is assessed in qualitative and/or quantitative terms. A testing device is likewise disclosed, in which a force is exerted on the planar substrate by means of a movable element in the form of a dumbbell-shaped magnetic stirring rod acting on the side of the planar substrate facing away from the applied adhesive planar body and rotating below the substrate, deforming same.

Abstract: In a dynamic mechanical analysis, a test specimen (2) is coupled to an excitation device (4) by means of a holder device (3). The excitation device (4) applies an excitation force comprised of a static pre-tensioning force component and a time-variable force component to the test specimen, and a deformation of the test specimen (2) is measured by means of one or more displacement sensors (5). The method includes a test phase with the steps: applying the excitation force to the test specimen; while said excitation force is in effect, determining at least one decision parameter, said decision parameter being indicative of a degree of slack in said coupling of the test specimen; comparing said decision parameter to at least one reference value; based on said comparison, determining whether or not the test specimen is coupled to the excitation device in a completely slack-free state, so that physical values derived from said measurements of the deformation will not be subject to errors caused by an insufficient amount of said pre-tensioning force component.

Abstract: A plurality of fatigue life test strips (16, 18, 20, 22) has each of the strips anchored to a base (12) which is subject to thermal cycling and consequent dimensional change which causes fatigue. The base is, at best, semiconductive, and the strips are conductive. The conductivity of each of the strips is measured by test circuit (52) so that, when one fails due to fatiguing, the failure is signaled.
