摘要：

This project offers a methodology for the analysis of resistographic profiles obtained from samples of wood and the extraction of precise data from these profiles. Tests were conducted on healthy samples of wood from six different species, as well as on "old" wood in use as part of timber structures with an age of 80-120 years. Based on the data collected using the resistograph, a series of variables was determined, and statistically analysed. An analysis of the data reveals the close relation between the resistographic variables and wood density (R(2) > 90%). Equally, in the case of healthy wood, an analysis of the defined variables permits the identification of the species of the sample with a very high probability and, therefore, its indirect resistance values.
