Principle Of Operation
The test fixture consists of two steel specimen holders. The upper holder is attached to the load cell of the test system via a flexible coupling to provide optimum alignment. The lower holder mounts directly to the test machine base adaptor.
The prepared specimen is simply inserted from the front into the holders, which are designed to apply the test load to the specimen shoulders.
The force required to break the adhesive bond is applied by moving the crosshead in the tensile direction.
- Adhesive bond strength of wood according to ASTM D 897
