The paper deals with the mechanical assessment and diagnosis of structural timber based on Non Destructive Testing (NDT) evaluation. An experimental campaign has been developed on old chestnut elements, including the following NDT methods: hygrometric tests to estimate wood moisture content, ultrasonic investigations to determine stress wave properties, sclerometric tests to assess material hardness and superficial consistence, resistographic measurements to detect internal defects and density variations. The data are statistically examined, providing reasonable correlations among results of the different non destructive tests, using the linear regression model.
