Imont project (2004-2006): research for a machine stress grading of sawn timber for structural use obtained from lumber of various species (fir, spruce, larch, Douglas fir, black pine and chestnut) coming from Trentino Alto-Adige, Toscana and Calabria. This study allowed the adjustment of an efficient method of machine grading, the increment of visual grading efficiency, the publication of resistant profiles for the Italian structural lumber by wood species, geographic origin and category of classification. The results of the project have been used to update the Italian standard UNI 11035 "Structural timber - Visual strength grading for italian structural timbers: terminology and measurement of features".
