Peel test fixture 2820 series

specimen

The fixtures consist of two roller bearings in a frame that is connected to the test system via a pivoting adapter. This design ensures that alignment between the fixture and the test specimen occurs as soon as force is applied and that the direction of the applied force is through the centerline of the fixture. As the crosshead is driven in the tensile direction, the load weighing system measures the force required to peel the flexible adherend from the rigid adherend. There are two different versions of the fixture. One complies with the ASTM D3167 and the other with ISO 4578, EN 2243-2 and EN 1464 standards. While the standards are very similar there are slight differences in the specified peel area dimensions and the diameter of the roller bearings. While the differences are small, there is a risk of getting variation in the test results.
