Method and means for testing the strength of a bonding between two specimen elements

A method for testing the tensile strength of a bonding between two elongated shaped specimen elements comprising the steps of:

• a) providing two essentially U-shaped transmission elements having two legs and a connecting element, wherein the two legs are arranged essentially parallel and spaced apart to each other and connected by the connecting element forming a groove, wherein the legs of each transmission element are engageable with one of the specimen elements and the connecting element is engageable with a press;
• b) bonding said two elongated shaped specimen elements crosswise at bonding areas by means of a bonding agent, wherein the bonding area of each specimen element is situated between two protrusion areas on the specimen element and wherein in the bonding areas the specimen elements overlap each other;
• c) engaging each transmission element with one specimen element by means of the legs of the transmission element via the protrusion areas of the specimen element, so that each specimen element is placed with its bonding area in the groove of one transmission element;
• d) applying a force on the connecting element of each transmission element with a press, wherein the forces are directed towards each other essentially in one action line forcing the transmission elements towards each other and applying a tensile force on the adhesive;
• and
• e) measuring at least one force applied with a force measurement device.
