In this paper the trend of correlations between compressive strength parallel and perpendicular to fibers is studied, obtained by standard destructive tests, and parameters of the esclerometer tests. For purposes of comparison with other non-destructive ultrasound tests were also carried out. Three series of specimens were taken from a log of Eucalyptus saligna and tested in wood saturated condition. Results of the esclerometer impacts for the three directions evaluated (parallel to fiber, radial and tangential) coefficients of variation less than 9% were observed. From the analysis of trend of correlations of compressive strength with the results of esclerometer and ultrasound, better adjustments for the direction parallel to the fibers were observed. Considering the results, it can be concluded that the esclerometer technique was able to identify the homogeneity of the batch tested, justifying to have possibilities of applications to the timber.153322328NBR7190 -Projeto de estruturas de madeira (1997), p. 197. , ABNT -Associação Brasileira de Normas Técnicas.
