<p>Method for testing the stability of metal masts mounted in the ground, where reduction of stability is especially due to corrosion damage. According to the method, the mast is set vibrating, the vibration is measured with measurement means and the vibration measurement data are compared with recorded reference measurement data. - The inventive method is based on the idea that frequency of mast vibrations yields information relating to the corrosion impairment of the mast.</p> |
