1. Bend test - is a simple and inexpensive qualitative test that can be used to evaluate both the
ductility and soundness of a material. It is often used as a quality control test for butt-welded
joints, having the advantage of simplicity of both test piece and equipment.

5. ISO 13910 – Timber structures – Bending strength and stiffness:
Test methods within the specification include flexure, compression, tension, shear, and torsion
testing. The bending strength and stiffness test setup involves a four-point bend fixture.
Procedure:
1. Prepare your test specimen in accordance with the standard, noting all relevant
histories of the treatment, conditioning, etc. of the wood specimen that could affect its
strength.
2. Adjust the flexure fixture in accordance with the specimen size and desired purpose of
the testing.
3. Insert the test specimen into the flexure fixture.
4. Apply the flexure load to the specimen at the constant rate of speed defined in the
standard.
5. Continue the test until failure, while recording load & deflection data at first failure,
maximum load, and other points of sudden change.
