A method for testing poles ( 1 ) including the steps of applying a first load to a pole ( 1 ), measuring the movement of the pole ( 1 ), at least partially de-loading the pole ( 1 ) to a second load, measuring the movement of the pole ( 1 ), and using the change in the movement measurements under the respective loads to calculate the pole ( 1 ) stiffness.
