This method can only be used for comparing adhesives, and the results cannot be used for design purposes. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 291 :1 997, Plastics — Standard atmospheres for conditioning and testing .

ISO 1 3895:1 996, Adhesives — Guidelines for the surface preparation of plastics . 3 Principle The time to rupture of a bonded lap-shear specimen is measured under a specific load. 4 Apparatus 4.1 Test rig, capable of holding specimens securely at one end, in the vertical position, the other end of each specimen being linked to a fixture capable of receiving different weights in order to vary the load. The direction of the load shall coincide with the longitudinal axis of the specimen. The rig shall be capable of loading several specimens simultaneously. It shall be designed such that any vibration associated with breakage of one specimen will not influence the remaining specimens. The rig shall be placed in an environmentally controlled cabinet or be designed such that the specimens are tested under controlled conditions. 5 Specimens 5.1 Adherend material The adherends shall be made of metal, rigid plastic, rigid fibre-reinforced plastic, wood or wood-based material. 5.2 Shape and dimensions Specimens shall be as shown in figure 1 for all materials except wood and as shown in figure 2 for wood. The thickness of the adherends shall be sufficient to avoid significant plastic deformation.5.3 Cleaning and surface treatment of adherends The cleaning and surface treatment of adherends...
